Run Greasemonkey script on the same page, multiple times?

rated 0 times [ 26] [ 4] / answers: 1 / hits: 19638 / 12 Years ago, mon, june 25, 2012, 12:00:00

I'm totally new to Greasemonkey, javascript, in fact all the UI stuff.

Requirement: Userscript is run by GS once after the page loads. However, I need the same script to be run multiple times without refresh

Use case: For ex, Amazon.com search happens using Ajax. I need to embed a custom element in the search results.

I need to inject my content to the search-results-div along with the results every time a search happens in the same page (there's no page refresh)

My current script runs only with the page refresh.

I hope above explanation is clear. Please help.

The simplest, most robust way is to use the waitForKeyElements() utility.

Here is a complete script that uses jQuery and 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==

/*- The @grant directive is needed to work around a design change

    introduced in GM 1.0.   It restores the sandbox.

*/



function addCustomSearchResult (jNode) {

    //***** YOUR CODE HERE *****

    jNode.prepend (

        '<div id=result_000 class=fstRow>Buy my stuff, instead!</div>'

    );

}



waitForKeyElements (#atfResults, addCustomSearchResult);
