Most basic javascript templating solution...?

I am looking to create a variable that is a template for repatative elements of my site. I however am only using it infrequently so I do not wish to use a javascript templating engine or library.

I am using jquery... if that effects anyones approach.

This is one of my templates.

$html_template = json_encode("
var html = '<a href=\"javascript:ajax(\'#content\',\'{$conf['dir']['web_url']}profile.php?user_id='+data.id+'\');\">
<div id=\"'+data.id+'\" class=\"fb_user\">
    <img alt=\"'+data.n开发者_开发百科ame+'\" height=\"50\" width=\"50\" />
    <p>
        '+data.first_name+'
        <br/>
        '+data.last_name+'
    </p>
</div>';");

I have gotten so lost in escaping I can't work out where I have gone wrong. The plan is to use eval within the templating function to replace the variables.

Hope someone can help

1. Use an editor with good highlighting and you will see where to escape.
2. The apostrophes (') that are inside the javascript code shouldn't be escaped, use double backslash (\) instead, so the javascript will see a single backslash and therefore will escape the apostrophe.
3. In the anchor don't use javascript code as href, use "#" for link and add onClick="...".
4. I don't think "ajax" is a jQuery function, perhaps you meant "$.ajax", but it has different parameters, may be you should read its manual.
5. Try to implement it in pure html and js before writing it in php and you'll know where to escape (after it works in first place).
