Working with url and strings in javascript

Question

I'm working with cordova 3.5

I've an iframe setup as following:

  <iframe src="http://localhost/test/index.html" style="width:100%;height:90%" onLoad="checkforclose(this);"></iframe>

And the JS is the following:

<script type="text/javascript">
function checkforclose(pageURL) { 
    var urlFrame = pageURL.contentWindow.location; //WORKS
    alert(urlFrame); //WORKS
    alert(urlFrame.indexOf('test')); //DOESN'T WORK EVEN FOR ANY VALUE - RETURNS UNDEFINED
}   
</script>

The snippet works, because the first two lines works. But the third don't. Even more, in JSFiddler works. I'm very lost with this.

Thanks in advance

yes but it won't work because the iframe is pointing to my localhost — Leandro Bardelli

Try alert(urlFrame.href.indexOf('test'));

The reason it doesn't work is you are calling indexOf on a window.location (urlFrame) Object. It is throwing an error because indexOf() is not a function property of window.location.

Sorry, I don't understand you. You mean that: pageURL.contentWindow.location.indexOf doesn't work?

Yes, that is correct. indexOf will only work on Arrays ( >IE8 ) and Strings

Even more, this was a Kobashi Maru to me, so easy for you and hard to solve to me :S I must have think out of the box more often.

I use the Chrome browsers developement tools to debug the JS you wrote. This way I can see errors in the console and set breakpoints to debug the code.

I was blocked in the android emulator :S Bad for me. I'll begin to work as you

Try this...

var urlFrame = pageURL.src

You are getting undefined because value of "urlFrame" is empty.
