To hide rows in a grid based on the value of a dropdown column, you can utilize JavaScript to dynamically manipulate the grid's DOM elements. Here's a step-by-step approach:
Identify the Dropdown Column: Determine the ID or class of the dropdown column that will be used as the criteria for hiding rows.
Capture Dropdown Value Changes: Implement an event listener that detects changes in the dropdown selection. This event listener will trigger the function responsible for hiding or unhiding rows.
Loop through Grid Rows: Iterate through all rows of the grid using JavaScript's DOM manipulation methods.
Compare Dropdown Value: For each row, compare the value of the dropdown cell with the value that triggers row hiding.
Hide or Unhide Rows: Based on the comparison, hide or unhide the current row using JavaScript's DOM manipulation methods.
Here's an example JavaScript code snippet https://echat.date that demonstrates the concept:
JavaScript
// Identify the dropdown column ID
const dropdownId = 'dropdown-column-id';
// Capture dropdown value changes
document.getElementById(dropdownId).addEventListener('change', handleDropdownChange);
function handleDropdownChange() {
const selectedValue = document.getElementById(dropdownId).value;
// Loop through grid rows
const gridRows = document.querySelectorAll('.grid-row');
for (const row of gridRows) {
const dropdownCellValue = row.querySelector('.dropdown-cell-class').textContent;
// Hide or unhide rows based on comparison
if (dropdownCellValue === selectedValue) {
row.style.display = 'none';
} else {
row.style.display = 'block';
}
}
}
This code snippet assumes https://www.developerbook.net/ the grid has a CSS https://koows.com/omegle class grid-row for each row and the dropdown cell has a CSS class dropdown-cell-class. Adjust the selectors as needed for your specific grid structure.
