HTML到Haml的转换javascript

Question

I have this html code. I want it to convert to haml format. -->

    <script type="text/javascript">
        window.jQuery || document.write("<script src='assets/jquery-2.0.3.min.js'>"+"<"+"/script>");
    </script>

    <!--<![endif]-->

This is how I convert it to haml.

/ [if !IE]>
  :javascript
    window.jQuery || document.write("<script src='assets/jquery-2.0.3.min.js'>"+"<"+"/script>");
/ <![endif]

but I got this error Illegal nesting: nesting within a tag that already has content is illegal. Any idea why? or what is the right way to convert this code to haml?

Answer 1

Haml includes support for IE conditional comments , the sytax is / [cond] , without the closing >

In your first line:

/ [if !IE]>

the last > is being treated as content, and you also nest the :javascript filter as content. This is why you get the nesting within a tag that already has content is illegal error.

However, you can't use the !IE condition this way , you'll end up with a single comment that all browsers will ignore. You'll need to no something like this, using literal HTML:

<!--[if !IE]> -->
:javascript
  window.jQuery || document.write("<script src='assets/jquery-2.0.3.min.js'>"+"<"+"/script>");
<!-- <![endif]-->
