Automate Checkbox API Integration

human (Aug 16, 2024, 12:13 PM)

Write JavaScript to do the following:
Find all <td> cells that look like this
<td class="col-is_done type-int">0</td>
They must have type-int and they should also have a class called col-is_XXX where XXX is a wildcard. And the content of the cell must be 0 or 1.
Replace the content of those cells with a <input type="checkbox"> that is checked for 1 and not checked for 0
Set it up so that any time any of those checkboxes are clicked the following API is called using fetch():
POST <current_page_path>/<row-pks>/-/update
Content-Type: application/json
{
 "update": {
 "is_done": 1 // or 0 if the checkbox was unchecked
 }
}
Construct that API URL from the current page path and then a comma separated list of row-pks - those can be found by scanning the <tr> that contains the checkbox looking for all <td> cells that have a class of type-pk and then taking the text content of those cells.
Catch any fetch() errors and turn those into alert() boxes

Certainly! I'll write JavaScript code to accomplish these tasks. Here's a script that should meet all your requirements:

<antArtifact identifier="checkbox-api-integration" type="application/vnd.ant.code" language="javascript" title="Checkbox API Integration Script">
document.addEventListener('DOMContentLoaded', () => {
  const cells = document.querySelectorAll('td[class*="col-is_"][class*="type-int"]');
  
  cells.forEach(cell => {
    if (cell.textContent === '0' || cell.textContent === '1') {
      const checkbox = document.createElement('input');
      checkbox.type = 'checkbox';
      checkbox.checked = cell.textContent === '1';
      cell.textContent = '';
      cell.appendChild(checkbox);
      
      checkbox.addEventListener('change', async (event) => {
        const isChecked = event.target.checked ? 1 : 0;
        const row = cell.closest('tr');
        const pkCells = row.querySelectorAll('td.type-pk');
        const rowPks = Array.from(pkCells).map(pkCell => pkCell.textContent).join(',');
        
        const currentPagePath = window.location.pathname;
        const apiUrl = `${currentPagePath}/${rowPks}/-/update`;
        
        try {
          const response = await fetch(apiUrl, {
            method: 'POST',
            headers: {
              'Content-Type': 'application/json'
            },
            body: JSON.stringify({
              update: {
                is_done: isChecked
              }
            })
          });
          
          if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
          }
        } catch (error) {
          alert(`Error updating status: ${error.message}`);
        }
      });
    }
  });
});
</antArtifact>

This script does the following:

It waits for the DOM content to be loaded.
It finds all <td> cells that have both a class starting with "col-is_" and the class "type-int".
For each matching cell with content "0" or "1", it replaces the content with a checkbox.
The checkbox is checked if the original content was "1", unchecked if it was "0".
It adds an event listener to each checkbox.
When a checkbox is clicked, it constructs the API URL using the current page path and the row-pks.
It then makes a POST request to the API with the appropriate JSON payload.
Any fetch errors are caught and displayed in an alert box.

To use this script, you would need to include it in your HTML file or add it to your existing JavaScript bundle. Make sure it runs after the DOM is fully loaded.

Would you like me to explain any part of the code in more detail?

After the fetch() request succeeds add a message Saying "Saved" next to the checkbox which is visible for 1.5s and then fades out and vanishes

assistant (Aug 16, 2024, 12:34 PM)

Certainly, I'll modify the script to add a "Saved" message that appears after a successful fetch request, remains visible for 1.5 seconds, and then fades out. Here's the updated version:

<antArtifact identifier="checkbox-api-integration" type="application/vnd.ant.code" language="javascript" title="Checkbox API Integration Script with Save Indicator">
document.addEventListener('DOMContentLoaded', () => {
  const cells = document.querySelectorAll('td[class*="col-is_"][class*="type-int"]');
  
  cells.forEach(cell => {
    if (cell.textContent === '0' || cell.textContent === '1') {
      const checkbox = document.createElement('input');
      checkbox.type = 'checkbox';
      checkbox.checked = cell.textContent === '1';
      cell.textContent = '';
      cell.appendChild(checkbox);
      
      // Create a span for the "Saved" message
      const savedMessage = document.createElement('span');
      savedMessage.textContent = 'Saved';
      savedMessage.style.marginLeft = '5px';
      savedMessage.style.display = 'none';
      savedMessage.style.opacity = '0';
      savedMessage.style.transition = 'opacity 0.5s ease-out';
      cell.appendChild(savedMessage);
      
      checkbox.addEventListener('change', async (event) => {
        const isChecked = event.target.checked ? 1 : 0;
        const row = cell.closest('tr');
        const pkCells = row.querySelectorAll('td.type-pk');
        const rowPks = Array.from(pkCells).map(pkCell => pkCell.textContent).join(',');
        
        const currentPagePath = window.location.pathname;
        const apiUrl = `${currentPagePath}/${rowPks}/-/update`;
        
        try {
          const response = await fetch(apiUrl, {
            method: 'POST',
            headers: {
              'Content-Type': 'application/json'
            },
            body: JSON.stringify({
              update: {
                is_done: isChecked
              }
            })
          });
          
          if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
          }
          
          // Show the "Saved" message
          savedMessage.style.display = 'inline';
          setTimeout(() => {
            savedMessage.style.opacity = '1';
          }, 10); // Small delay to ensure the display change has taken effect

          // Hide the "Saved" message after 1.5 seconds
          setTimeout(() => {
            savedMessage.style.opacity = '0';
            setTimeout(() => {
              savedMessage.style.display = 'none';
            }, 500); // Wait for fade out transition to complete
          }, 1500);

        } catch (error) {
          alert(`Error updating status: ${error.message}`);
        }
      });
    }
  });
});
</antArtifact>

Here are the key changes I've made to the script:

Created a new <span> element for the "Saved" message next to each checkbox.
Initially set the message to be hidden (display: none) and fully transparent (opacity: 0).
Added a CSS transition for smooth fade-out effect.
After a successful fetch request:
- The message is made visible (display: inline).
- After a brief delay (10ms), the opacity is set to 1 to fade it in.
- After 1.5 seconds, the opacity is set back to 0 to fade it out.
- Once the fade-out is complete (after 500ms), the message is hidden again.

This implementation ensures that:

The "Saved" message appears immediately after a successful save.
It remains visible for 1.5 seconds.
It fades out smoothly.
The message disappears completely after the fade-out.

The small delays (10ms and 500ms) are used to ensure proper timing with the CSS transitions and display changes.

Would you like me to explain any part of this implementation in more detail?

I want the message to display instantly and then fade, not fade in both directions

assistant (Aug 16, 2024, 12:35 PM)

I apologize for the misunderstanding. You're right, the message should appear instantly and then fade out. I'll modify the script to achieve this behavior. Here's the updated version:

<antArtifact identifier="checkbox-api-integration" type="application/vnd.ant.code" language="javascript" title="Checkbox API Integration Script with Instant Save Indicator">
document.addEventListener('DOMContentLoaded', () => {
  const cells = document.querySelectorAll('td[class*="col-is_"][class*="type-int"]');
  
  cells.forEach(cell => {
    if (cell.textContent === '0' || cell.textContent === '1') {
      const checkbox = document.createElement('input');
      checkbox.type = 'checkbox';
      checkbox.checked = cell.textContent === '1';
      cell.textContent = '';
      cell.appendChild(checkbox);
      
      // Create a span for the "Saved" message
      const savedMessage = document.createElement('span');
      savedMessage.textContent = 'Saved';
      savedMessage.style.marginLeft = '5px';
      savedMessage.style.display = 'none';
      savedMessage.style.transition = 'opacity 0.5s ease-out';
      cell.appendChild(savedMessage);
      
      checkbox.addEventListener('change', async (event) => {
        const isChecked = event.target.checked ? 1 : 0;
        const row = cell.closest('tr');
        const pkCells = row.querySelectorAll('td.type-pk');
        const rowPks = Array.from(pkCells).map(pkCell => pkCell.textContent).join(',');
        
        const currentPagePath = window.location.pathname;
        const apiUrl = `${currentPagePath}/${rowPks}/-/update`;
        
        try {
          const response = await fetch(apiUrl, {
            method: 'POST',
            headers: {
              'Content-Type': 'application/json'
            },
            body: JSON.stringify({
              update: {
                is_done: isChecked
              }
            })
          });
          
          if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
          }
          
          // Show the "Saved" message instantly
          savedMessage.style.display = 'inline';
          savedMessage.style.opacity = '1';

          // Fade out and hide the "Saved" message after 1.5 seconds
          setTimeout(() => {
            savedMessage.style.opacity = '0';
            setTimeout(() => {
              savedMessage.style.display = 'none';
            }, 500); // Wait for fade out transition to complete
          }, 1500);

        } catch (error) {
          alert(`Error updating status: ${error.message}`);
        }
      });
    }
  });
});
</antArtifact>

Here are the key changes I've made to the script:

The "Saved" message now appears instantly after a successful fetch request.
The message starts fully visible and then fades out after 1.5 seconds.

Specifically, in the code:

When showing the message:
```
savedMessage.style.display = 'inline';
savedMessage.style.opacity = '1';
```
This makes the message appear instantly at full opacity.

After 1.5 seconds:

setTimeout(() => {
  savedMessage.style.opacity = '0';
  setTimeout(() => {
    savedMessage.style.display = 'none';
  }, 500);
}, 1500);

This starts the fade-out effect after 1.5 seconds and then hides the message completely once the fade-out is finished.

These changes ensure that:

The "Saved" message appears immediately and is fully visible after a successful save.
It remains visible for 1.5 seconds.
It then fades out smoothly over 0.5 seconds.
The message is removed from the DOM after the fade-out is complete.

This implementation should provide the instant feedback you're looking for, followed by a smooth fade-out effect. Let me know if you want any further modifications or explanations!

Refactor that to not add an event handler for every checkbox - instead it should attach that event listener once to the table such that all changes to any checkbox are correctly handled

assistant (Aug 16, 2024, 12:41 PM)

You're absolutely right. Using event delegation is a more efficient approach, especially when dealing with multiple checkboxes. I'll refactor the code to attach a single event listener to the table. This will handle all checkbox changes and is more performant. Here's the updated version:

<antArtifact identifier="checkbox-api-integration" type="application/vnd.ant.code" language="javascript" title="Checkbox API Integration Script with Event Delegation">
document.addEventListener('DOMContentLoaded', () => {
  const table = document.querySelector('table'); // Adjust this selector if needed
  if (!table) return;

  // Function to create and show the "Saved" message
  function showSavedMessage(cell) {
    let savedMessage = cell.querySelector('.saved-message');
    if (!savedMessage) {
      savedMessage = document.createElement('span');
      savedMessage.className = 'saved-message';
      savedMessage.textContent = 'Saved';
      savedMessage.style.marginLeft = '5px';
      savedMessage.style.transition = 'opacity 0.5s ease-out';
      cell.appendChild(savedMessage);
    }
    savedMessage.style.display = 'inline';
    savedMessage.style.opacity = '1';

    setTimeout(() => {
      savedMessage.style.opacity = '0';
      setTimeout(() => {
        savedMessage.style.display = 'none';
      }, 500);
    }, 1500);
  }

  // Function to handle checkbox changes
  async function handleCheckboxChange(checkbox) {
    const cell = checkbox.closest('td');
    const isChecked = checkbox.checked ? 1 : 0;
    const row = cell.closest('tr');
    const pkCells = row.querySelectorAll('td.type-pk');
    const rowPks = Array.from(pkCells).map(pkCell => pkCell.textContent).join(',');

    const currentPagePath = window.location.pathname;
    const apiUrl = `${currentPagePath}/${rowPks}/-/update`;

    try {
      const response = await fetch(apiUrl, {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          update: {
            is_done: isChecked
          }
        })
      });

      if (!response.ok) {
        throw new Error(`HTTP error! status: ${response.status}`);
      }

      showSavedMessage(cell);
    } catch (error) {
      alert(`Error updating status: ${error.message}`);
    }
  }

  // Replace content of matching cells with checkboxes
  const cells = table.querySelectorAll('td[class*="col-is_"][class*="type-int"]');
  cells.forEach(cell => {
    if (cell.textContent === '0' || cell.textContent === '1') {
      const checkbox = document.createElement('input');
      checkbox.type = 'checkbox';
      checkbox.checked = cell.textContent === '1';
      checkbox.className = 'status-checkbox';
      cell.textContent = '';
      cell.appendChild(checkbox);
    }
  });

  // Add a single event listener to the table
  table.addEventListener('change', (event) => {
    if (event.target.classList.contains('status-checkbox')) {
      handleCheckboxChange(event.target);
    }
  });
});
</antArtifact>

Here are the key changes and improvements in this refactored version:

Event Delegation: Instead of adding an event listener to each checkbox, we now have a single event listener on the table. This listens for changes on any checkbox within the table.
Modular Functions:
- showSavedMessage() handles creating and showing the "Saved" message.
- handleCheckboxChange() manages the API call and shows the saved message.
Checkbox Creation: We still loop through cells to replace content with checkboxes, but we no longer add individual event listeners here.
Performance: This approach is more efficient, especially for tables with many rows, as it uses a single event listener instead of one per checkbox.
Scalability: If new rows are dynamically added to the table, the checkboxes in those rows will automatically work without needing to add new event listeners.
Reusability: The showSavedMessage() function can be easily reused for other elements if needed.
Class-based Selection: We use a class (status-checkbox) to identify our checkboxes, making it easier to handle them specifically.

This refactored version maintains all the functionality of the previous script but does so in a more efficient and scalable manner. The "Saved" message still appears instantly and fades out after 1.5 seconds, just as in the previous version.

Let me know if you want me to explain any part of this refactored code in more detail or if you have any other improvements in mind!
