ICanHaz.js - Possible to put a while loop in template?

Question

Let's say I have a element, and inside it want to put an indefinite number of

items (based on the user's choices). Is there a way to create an ICanHaz template that allows for some sort of while loop. For instance:

    <ul>
     for(i = 0; i < numOfLi; i++)
       <li> {{ stuff }} </li>
    </ul>

Answer 1

icanhaz (moustache) does include a way to loop.

In javascript:

var listOfStuff = {stuff: [ 
                      {key: "1", desc: "First"},
                      {key: "2", desc: "Second"}
                  ]};
$("#mySelectBox").append(ich.myTemplate(listOfStuff));

In your view:

<script id="myTemplate" type="text/html">
  {{#stuff}}
    <option value="{{key}}">{{desc}}</option>
  {{/stuff}}
</script>

<select id="mySelectBox">
</select>

The {{#stuff}} and {{/stuff}} delimit the list. Look at the Sections part of moustache for details.

Answer 2

I'm not sure about iCanHaz, but John Resig (creator of JQuery) posted this method on his blog:

See JavaScript Micro-Templating

A sneak peak...

<script type="text/html" id="user_tmpl">
  <% for ( var i = 0; i < users.length; i++ ) { %>
    <li><a href="<%=users[i].url%>"><%=users[i].name%></a></li>
  <% } %>
</script>

Nope. Can't be done. You need to render the html dynamically.
