Checking Element Visibility in jQuery
In jQuery, you can toggle an element's visibility using the .hide(), .show(), or .toggle() methods. To determine whether an element is currently visible or hidden, you can leverage the following approaches:
Single Element Check:
The provided answer suggests using $(element).is(":visible") or $(element).is(":hidden") to check the CSS "display" property of a single element. This ignores the "visibility" property, which may be set to hidden or visible while the element remains on the screen.
Example:
// Check if the element is visible
if ($(element).is(":visible")) {
console.log("The element is visible.");
} else {
console.log("The element is hidden.");
}
Element Collection Check:
You can also use the $.grep() function to determine which elements in a collection are visible or hidden. This checks both the "display" and "visibility" properties.
Example:
// Get an array of visible elements
var visibleElements = $.grep($(".elements"), function(element) {
return $(element).is(":visible");
});
Note:
The jQuery documentation recommends using is(':visible') instead of is(':hidden'), as the former is more accurate and eliminates false positives that can occur due to specific CSS rules.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
