Can Multiple jQuery Versions Coexist on a Single Webpage?

Can jQuery Versions Coexist on a Webpage?

Numerous web projects rely on jQuery, and sometimes, multiple versions of this library may be required on a single webpage. This scenario arises when customers have pre-existing jQuery installations on their sites, but a project needs to use a newer version. Can these different versions coexist harmoniously?

A Straightforward Solution Using noConflict Mode

Fortunately, jQuery offers a solution to this dilemma: noConflict mode. By invoking this mode, you can isolate multiple jQuery versions on the same page without interference.

Here's how it works:

  1. Load multiple jQuery versions.
  2. Use var jQuery_X_Y_Z = $.noConflict(true); to store each version in a separate variable.
  3. To interact with a specific jQuery version, use jQuery_X_Y_Z(selector).function(); instead of $(selector).function();

This method allows each jQuery version to operate independently within its designated scope, preventing conflicts.

Example:

<!-- Load jQuery 1.1.3 -->
<script src="http://example.com/jquery-1.1.3.js"></script>
<script>
  var jQuery_1_1_3 = $.noConflict(true);
</script>

<!-- Load jQuery 1.3.2 -->
<script src="http://example.com/jquery-1.3.2.js"></script>
<script>
  var jQuery_1_3_2 = $.noConflict(true);
</script>

Then, to manipulate DOM elements using jQuery 1.1.3, use jQuery_1_1_3(selector).function();, and for jQuery 1.3.2, use jQuery_1_3_2(selector).function();.

By utilizing this technique, you can seamlessly integrate multiple jQuery versions into your webpage, ensuring that both your code and your customers' existing jQuery installations coexist peacefully.

What is event bubbling and capturing in the DOM? 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? 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
