So let's say we have this code in an iFrame. I'm pretty sure the iFrame is from the same domain, that matters I think.
<div id="10">You become 1 best coder</div>
I want a Greasemonkey script which will run a script only if both "div id=10" and the text (or part of the text) is true.
I tried this:
// ==UserScript==
// @name Script
// @include https://www.somesite.com/*
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.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.
*/
var intv = setInterval(function() {
const sp = document.querySelector('#10'); // find id (some)
if (sp && sp.textContent === 'You become 1 best coder') {
alert('Hello world!');
}
}, 5000);
And this works on a regular page with regular content. But when the content I need the script to identify in order to run loads inside an iFrame, the script doesn't run.
Here is an example of the iFrame code:
<iframe src="something.php?text=M0000310y100g190e500A78014607601&lalala=tT6&ctrl=032a4c3342e76e97ea21821a5c5f800e&mamama=c2ed5535532cc20aef064db2b4" width="100%" height="100%" frameborder="0"></iframe>
I assume the iFrame is from the same domain, because if it was from a different domain the src="" would be different, I think...
Can anyone help? Thanks
First you need to get the iframe. If that is the only one then you can try ....
Note: Updated based on comment
// ==UserScript==
// @name Script
// @include https://www.somesite.com/*
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.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.
*/
const intv = setInterval(function() {
const iframe = document.querySelector('iframe[src*="something.php"]');
const sp = iframe && iframe.contentWindow.document.body.querySelector('#10'); // find id (some)
if (sp && sp.textContent === 'You become 1 best coder') {
alert('Hello world!');
}
}, 5000);
Update
iframe content are also document. If the code doesn't need to interact with the parent frame, you can inject the userscript in the target iframe document and run it there.
