YUI handlebars and IE8 IE7 compatibility

Post Posted: Mon Apr 02, 2012 3:11 pm

Hi everyone,

I can't get a simple handlebars example to work when I change the compatibility mode of IE to IE8 or IE7. it seems that the handlebars script tag 'text/x-handlebars-template' returns an empty string when Y.one('#list-template').get('text') is called. In IE9, it works fine. Am I doing something wrong?

Thanks.

Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
        "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
    <script src="http://yui.yahooapis.com/3.5.0pre5/build/yui/yui-min.js" type="text/javascript"></script>
    <script type="text/javascript">
        YUI().use('handlebars', 'node-base', function (Y) {
            // Extract the template string and compile it into a reusable function.
            var source   = Y.one('#list-template').get('text'),
                    template = Y.Handlebars.compile(source),
                    html;

            // Render the template to HTML using the specified data.
            html = template({
                items: [
                    {name: 'pie', url: 'http://pieisgood.org/'},
                    {name: 'mountain dew', url: 'http://www.mountaindew.com/'},
                    {name: 'kittens', url: 'http://www.flickr.com/search/?q=kittens'},
                    {name: 'rainbows', url: 'http://www.youtube.com/watch?v=OQSNhk5ICTI'}
                ]
            });

            // Append the rendered template to the page.
            Y.one('body').append(html);
        });
    </script>
</head>
<body>
<script id="list-template" type="text/x-handlebars-template">
    <p>YUI is brought to you by:</p>

    <ul>
        {{#items}}
        <li><a href="{{url}}">{{name}}</a></li>
        {{/items}}
    </ul>
</script>
</body>
</html>

So if I do
Code:
document.getElementById("list-template").innerHTML
Instead of use YUI to grab the contents of the template, then it works. I guess this might be a feature enhancement for the Y.Node module?

Have you tried waiting for the domready event with Y.on('domready', fn)?

Hi Juan,

Thank you for your suggestion. It's exactly what I needed. :)

Scratch that. I spoke too soon! I forgot to change the call from using document.getElementById() to Y.one().get('text').

Executing the logic within the 'domready' callback does not fix the issue.

Ok, I looked up the code. node.get('text') uses textContent or innerText. I don't have IE8 around at the moment so I can't check, but it's possible IE < 9 doesn't have innerText for script tags. Have you tried node.getContent() or node.get('innerHTML')?

Nice! Thanks a bunch!

Using the .getHTML() or .get('innerHTML') works fine across the IE versions. Guess you are correct about IE7 and IE8 not supporting .get('text').

.getContent() is deprecated so I wont use that one.

Thank you again!

Oh I just double checked the API doc. In stage, it's for YUI 3.5 pre5 that it has been deprecated :) For YUI 3.4.1, .getContent() is still good.

I have the same problem when I try to retrieve script content in a document fragment.

var script = content.all('script').toFrag().getHTML();

returns undefined.

Hmm,
var script = content.all('script').getHTML();
seems to work although it returns an array
