i'm unable to call the parent function from within iframe
Question
i've seen the other posts in regard to this, but the following method is not working for some reason.
onclick="parent.testing();"
now for the full story. i have an index.html that houses all the JS files. also within the index, i have an empty 'div' tag. with jQuery, i'm appending a page1.html file to the empty 'div'. so the index kinda looks like this:
<html>
<head>
<script files>
<script>
ready { function testing(){do stuff;} }
</script>
</head>
<body>
<div><iframe src="page1.html" (added via jQuery)></div>
</body>
</html>
now in the page1.html file, i'm trying to call a function when a link is clicked. but i'm receiving the following error:
Uncaught TypeError: Cannot call method 'testing' of undefined
i've also tried the following but they didn't work:
onclick="window.testing();"
onclick="window.frames[0].testing();"

Your parent page script isn't valid JavaScript, but assuming ready { ... } :
<script>
ready { function testing(){do stuff;} }
</script>
...is a simplification supposed to represent a document ready handler you are declaring testing() as a local function within that ready handler so it can only be accessed from within that ready handler. You need to make testing() global in the parent page:
<script>
$(document).ready({ /* your on ready stuff here */ });
function testing(){ /* do stuff; */ }
</script>
...and then you should be able to call it from the iframe using parent.testing() .

If I understand your question, your problem it's your function is not called, right? So maybe a solution is to put this in your "page1.html"
<script type="text/javascript" src="your_js_file"></script>
