AppJS - Unsafe JavaScript attempt to access frame with URL

Question

I'm making a desktop app where i can filter some specificed div inside of iframe with AppJS. I'm having a problem i couldn't hide some divs, there is a code:

    <!DOCTYPE html>
<html>
<style>

</style>
<head>
<link type="text/css" rel="stylesheet" href="style.css" />
<script>
function resizeIframe(newHeight)
{
    document.getElementById('iframe1').style.height = parseInt(newHeight,10) + 10 + 'px';
}
</script>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.js"></script>



</head>
<body onload='parent.resizeIframe(document.body.scrollHeight)'>
<h1>hello world</h1>
<iframe name='iframe1' id="iframe1" src="http://www.example.com" frameborder="0" border="0" cellspacing="0" style="border-style: none;width: 100%; height: 100%;"></iframe>


<script>
$(function(){
            var f=$('#iframe1')
            f.load(function(){ 
                f.contents().find('div').hide(); 
            })



        })

</script>
</body>
</html>

I got errors from console Unsafe JavaScript attempt to access frame with URL

Is possible to fix that?

js cannot accomplish task under normal condition....

You cannot do it directly because of Cross-Domain Policy.

However, you can first get content of the targeted url using php script from your own server (proxy) and then load its content in javascript/jquery. This is just a little fix and is not suitable for all kind of page you wish to load.

For example:

<iframe src="path_to_my_server_php_script/iframe.php?url=http://example.com"></iframe>

iframe.php basic code: {You could set headers or manipulate html code here too}

<?php
    $url = $_GET['url'];
    $html = file_get_contents($url);
    echo $html;
?>

Add an option to the create window call to turn off security:

disableSecurity:true

See wiki page for an example: https://github.com/appjs/appjs/wiki/app-object

This setting should turn off the cross-domain policy.
