How to define mustache partials in HTML?

this is my html: 

<script type="text/html" id="ul-template">
    <ul id="list">
        {{> li-templ}}
    </ul>
</script>  

<script type="text/html" id="ul-template2">
    <div id="list2">
        {{> li-templ}}
    </div>
</script>    

<script type="text/html" id="li-templ">
    <p>{{ name }}</p>
</script>

as you can see, I want to reuse the #li-templ part, but it seems that I have to write it into a file called li-templ.mustache then I can include it as partial?
can I just define them in the single html file?

ICanHaz.js (ICH) can help you with this.

ICanHaz.js: A simple/powerful approach for doing client-side templating with Mustache.js.

I've found that mixing templates (in scripts tags) with the ordinary HTML in the page messes with my code editor (syntax highlighting, indenting etcetera). Loading them as a separate server keeps your HTML clean.

Check out this ICH pull request for automatic loading of <script type="text/html" src="my-templates.html"></script> from your server to one template per file.

You could also load more than one template per remote HTML file this using simple code like:

function getTemplates(url) {
    $.get(url, function (response) {
        $('template', response).each(function () {
           ich.addTemplate(this.id, $(this).text());
        });
    });
}

Or, if you'd like ICH to load them automatically from urls in your page:

<head>
    <link rel="templates" type="text/html" href="my-templates.html">
</head>

$("link[type=templates]").each(function (index, link) {
    getTemplates(link.attr("href"));
});

In your my-templates.html

<templates>
    <template id="ul-template">
        <ul id="list">
            {{> li-templ}}
        </ul>
    </template>  

    <template id="ul-template2">
        <div id="list2">
            {{> li-templ}}
        </div>
    </template>    

    <template id="li-templ">
        <p>{{ name }}</p>
    </template> 
</templates>

I'm assuming you're using the JS flavor of Mustache.

In mustache.js an object of partials may be passed as the third argument to Mustache.render. The object should be keyed by the name of the partial, and its value should be the partial text.

You need to:

  1. Define some dummy data for name
  2. Get your partial template by getting the HTML of #li-templ
  3. Create an object with the name of the partial (li-templ) as the key
  4. Tell Mustache to render each template with the view data including your partial

Here's some jQuery to do just that:

var view = {"name" : "You"},
li = $('#li-templ').html(), 
partials = {"li-templ": li},
ul1 = Mustache.to_html($('#ul-template').html(), view, partials),
ul2 = Mustache.to_html($('#ul-template2').html(), view, partials);;

document.write(ul1, ul2);

Here's a jsFiddle of it all working- http://jsfiddle.net/maxbeatty/EYDfP/
