Storing HTML into a javascript variable

I'm having some trouble with some javascript. I'm using jQuery to dynamiclly add rows to a table. Additionally the javascript is being generated from some PHP and Kohana code.

Here is the script.

<script type="text/javascript">   
    function delExtensionNumber(element){
        $(element).prev().attr('value', 'X'); 
        $(element).parent().parent().hide();
    }

    function addExtensionNumber(){
        lines = <?php echo form::dropdown($ext_id."[did]", $lines, ''); ?>;
        extensions = <?php echo form::dropdown($ext_id."[extension]", $phones, ''); ?>;

        $('#line-extensions > tbody:last').append('<tr><td>'+lines+'</td><td>'+extensions+'</td><td><input type="hidden" name="'+<?php echo $ext_id;?>+'[state]" value="0" /><a class="hide" onclick="delExtens开发者_开发知识库ionNumber(this)"></a></td></tr>');

        <?php $ext_id++; ?>
    }
</script>

This works fine in Firefox. But in IE and Chrome it doesn't work. Nothing happens in google Chrome. In IE I get an error on the page. The error is a syntax error. It doesn't like the < character after the word line.

Ok, so I thought I better put some quotes around this string. But... when I do that nothing works.

I'm just going to assume that form::dropdown is spitting out plain HTML. In Firefox, this is being interpreted with E4X, and then turned back into a string when concatenated. IE and Chrome do not support E4X. To make it work, you could do something like this:

lines = <?php echo json_encode(form::dropdown(...)); ?>;

Edit: The reason it's not working when you're putting quotes around it is because the HTML contains quotes. The code above will escape the quotes correctly.

Chrome does not support XML literal syntax, you can't write e.g. line = <div>foo</div>, you have to enclose the data into a string.

lines = '<?php echo form::dropdown($ext_id."[did]", $lines, ""); ?>;'

could work (and you should possibly also escape ')

I strongly recommend you to use Jquery DOM Creation Plugin

• Easy DOM creation for jQuery

it would be a lot, easier.
