How Can I Execute Greasemonkey Scripts Multiple Times on a Single Page Without Refreshing?

Executing Greasemonkey Scripts Multiple Times on a Single Page

In Greasemonkey, we often encounter scenarios where we need to execute the same script multiple times on the same page without a page refresh. This can be achieved using the waitForKeyElements() utility.

Implementing Multiple Script Execution

Here's a complete script that demonstrates how to use waitForKeyElements() to alter Amazon search results:

// ==UserScript==
// @name     _Amazon Search, alter results
// @include  http://www.amazon.com/s/*
// @require  http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// ==/UserScript==

function addCustomSearchResult (jNode) {
    //***** YOUR CODE HERE *****
    jNode.prepend (
        '<div>

Explaining the Code

• waitForKeyElements is an event-checking utility that ensures the script only runs after specific elements have been loaded on the page.
• In this case, the script waits for the element with the ID #atfResults, which contains the search results.
• Once the element is present, the addCustomSearchResult function is executed, which adds a custom search result to the top of the results list.

Customizing the Script

The included code provides a simple example of altering search results. However, you can modify the script to perform any custom actions you require, such as embedding elements, modifying content, or rearranging search results.
