Question

I’m trying to have adsense javascript code added to a designated div location using jquery but it seems javascript code does not sit well inside a jquery variable. It executes. I’ve tried using php’s htmlentities to encode it for storage, but I can’t get it to decode naturally. What should I do? Do I need a javascript based replacement for htmlentities_decode?

This is how far I’ve gotten, and .html() is not automatically decoding the htmlentities encoded html.

var html_1 = "<?php echo htmlentities('<script>adsense ad code here</script>'); ?>";
if (html_1)
{
    jQuery('#id_wpt_adblock_1').html(html_1);
}

Answer 1

<script> tags are automatically executed when they are added to the DOM. So, when the string is added via html(), the <script> is added to the DOM, and than ran.

The issue here, is the <script> tags in the string. When the browser sees ’em, it may try to run the script. Try to change the string to this:

var html_1 = "<?php echo '<scr"+"ipt>adsense ad code here</scr"+"ipt>'; ?>";

This should output:

var html_1 = "<scr"+"ipt>adsense ad code here</scr"+"ipt>";

Which should work.

EDIT: You said this string is in a variable, try using str_replace to replace the tags.

var html_1 = "<?php echo str_replace(array('<script>','</script>'), array('<scr"+"ipt>', '</scr"+"ipt>'), $_SESSION['wpt_ad_content_1']); ?>";
