How to Correctly Enable Input Elements with jQuery Using prop()
Oct 19, 2024 pm 07:05 PM
Removing "disabled" Attribute Using jQuery
In your query, you seek to first disable and then enable input elements upon clicking a link. However, your code fails to remove the "disabled" attribute.
jQuery's prop() Method
To effectively disable or enable elements in jQuery, invariably employ the prop() method. This distinction matters since prop() deals with properties, whereas attr()/removeAttr() handles attributes.
In your particular instance, the correct code would be:
$("#edit").click(function(event){
event.preventDefault();
$('.inputDisabled').prop("disabled", false); // Elements are now enabled.
});

Prop() vs. attr()/removeAttr()
While attr()/removeAttr() can technically enable/disable elements, it's not recommended due to potential inconsistencies. Prop() explicitly manages property values, providing more reliable behavior.
Pre-jQuery 3.0 (before 2016)
removeAttr() removed the disabled attribute entirely, setting the property to false. Conversely, prop() only modified the property's boolean value.
jQuery 3.0 and Later
prop() remains the recommended approach, as removeAttr() now no longer sets the corresponding property to false. This distinction is essential for modern browsers that differentiate between attributes (initial values) and properties (current values).

Java vs. JavaScript: Clearing Up the Confusion

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

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.

How can you reduce the payload size of a JavaScript application?
Jun 26, 2025 am 12:54 AM
If JavaScript applications load slowly and have poor performance, the problem is that the payload is too large. Solutions include: 1. Use code splitting (CodeSplitting), split the large bundle into multiple small files through React.lazy() or build tools, and load it as needed to reduce the first download; 2. Remove unused code (TreeShaking), use the ES6 module mechanism to clear "dead code" to ensure that the introduced libraries support this feature; 3. Compress and merge resource files, enable Gzip/Brotli and Terser to compress JS, reasonably merge files and optimize static resources; 4. Replace heavy-duty dependencies and choose lightweight libraries such as day.js and fetch
