Including jQuery in Browser JavaScript Console for Non-jQuery Websites
Including jQuery in a browser's JavaScript console can be useful for debugging or quickly accessing jQuery functions. This is particularly helpful on websites that do not use jQuery.
Method:
To include jQuery in the JavaScript console, simply run the following code:
<code class="javascript">let jq = document.createElement('script');
jq.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(jq);
jQuery.noConflict();</code>
Explanation:
- The first line creates a new script element and sets its source as the jQuery library URL.
- The second line appends the script to the HTML head element.
- The third line includes jQuery into the console by calling the jQuery.noConflict() method. This ensures that any other JavaScript libraries on the page don't interfere with jQuery.
Additional Tips:
- If the website uses scripts that conflict with jQuery, you may encounter problems.
- To avoid the wait time for the script to load, you can modify the code as follows:
<code class="javascript">let jq = document.createElement('script');
jq.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js";
jq.onload = function() {
jQuery.noConflict();
console.log('jQuery injected');
};
document.getElementsByTagName('head')[0].appendChild(jq);</code>
- As an alternative, you can create a bookmark with the following code to inject jQuery with ease:
<code class="javascript">javascript: (function(e, s) {
e.src = s;
e.onload = function() {
jQuery.noConflict();
console.log('jQuery injected');
};
document.head.appendChild(e);
})(document.createElement('script'), '//code.jquery.com/jquery-latest.min.js')</code>The above is the detailed content of How to Include jQuery in Browser JavaScript Console for Non-jQuery Websites?. For more information, please follow other related articles on the PHP Chinese website!

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.
