Within my code, I am searching for the DIV element that has the class .se and also has the attribute display: block. Once found, I need to retrieve the ID of this particular DIV.
Unfortunately, it seems like my current approach is not correct.
var usedse = $(".se").filter(function() {
return $(this).css('display') === 'block';
}).attr("id");
Would you be able to assist me in resolving this issue? Thank you!
Here is my suggestion:
let visibleElementId = $('.se:visible').attr('id');
if(visibleElementId) {
alert(visibleElementId);
}
When working with .filter(), you have the ability to create custom logic... By targeting all elements with the class <div class='se'> and verifying that their CSS property display is set to block, you can retrieve the id of the first matching element.
var selectedSE = $("div.se").filter(function() {
return $(this).css('display') == 'block';
}).attr("id");
The method you have chosen to implement is inaccurate, consider the following alternative approach:
if ($("section.show").css('visibility') == 'visible') {
var sectionId = $("section.show").attr('id');
console.log(sectionId);
}
There are a couple of approaches you could take.
One option is to utilize the attribute selector, which will select all elements with the classes se and have the CSS property display set:
$(".se [style*='display']").attr('id');
Alternatively, you could use the .css() method to check the actual value of a specific CSS property:
var $possibles = $(".se"), id;
for ($el in $possibles)
if ($el.css('display') === 'block') id = $el.attr('id');
However, I'm curious about the reason behind this task. It feels like there might be a more optimal solution to the problem at hand... perhaps assigning a class to the element could simplify things (although this may not always be feasible depending on the situation)?
This could be the most effective way to achieve this task :)
id = $(".se[style*='display:block']").attr("id");
However, it is important to consider multiple instances when using classes as selectors, as there may be several div elements that need to be accessed. In such cases, try this approach instead:
$(".se[style*='display:block']").each(function(){
//You can perform actions on each element here
// Use `this` as a selector, for example
id = this.attr('id');
});
A quick note: Ensure that your selectors accurately target the desired item in terms of CSS. For instance,
style = $('element').attr('style');<div style="display:block".
To access style values set in the CSS, utilize the appropriate selector.
Remember that these are distinct aspects!
Here's another filtering version:
$('div.se').filter(function() {
return ( $(this).css('display') == 'block');
});
My main objective is to toggle the visibility of toggles while maintaining consistent formatting. However, I currently face an issue where using a filter achieves this but results in losing the current scroll position of the tabulator, which is not accepta ...
