JavaScript Micro-Templating from John Resig JavaScript Micro-Templating
Super-simple templating function that is fast, caches quickly, and is easy to use in the browser or nodejs.
<script type="text/html" id="tmpl">
<div id="<%= id %>" class="<%= (i % 2 == 1 ? "even" : "odd") %>">
<div>
<img src="<%= profileImageUrl %>"/>
</div>
<div class="contents">
<p><b><a href="/<%= fromUser %>"><%= fromUser %></a>:</b> <%= text %></p>
</div>
</div>
</script>
You would use it from script like so:
var resig = require('resig');
var results = document.getElementById('results');
results.innerHTML = resig('tmpl', dataObject);
You could pre-compile the results for later use. If you call the templating function with only an ID (or a template code) then it’ll return a pre-compiled function that you can execute later:
var userTmpl = resig('tmpl'), html = '';
for (var i = 0; i < users.length; i++ ) {
html += userTmpl(users[i]);
}
Finally, here's the code in full:

(function(){
var cache = {};
this.tmpl = function tmpl(str, data){
// Figure out if we're getting a template, or if we need to
// load the template - and be sure to cache the result.
var fn = !/\W/.test(str) ?
cache[str] = cache[str] ||
tmpl(document.getElementById(str).innerHTML) :
// Generate a reusable function that will serve as a template
// generator (and which will be cached).
new Function("obj",
"var p=[],print=function(){p.push.apply(p,arguments);};" +
// Introduce the data as local variables using with(){}
"with(obj){p.push('" +
// Convert the template into pure JavaScript
str
.replace(/[\r\t\n]/g, " ")
.split("<%").join("\t")
.replace(/((^|%>)[^\t]*)'/g, "$1\r")
.replace(/\t=(.*?)%>/g, "',$1,'")
.split("\t").join("');")
.split("%>").join("p.push('")
.split("\r").join("\\'")
+ "');}return p.join('');");
// Provide some basic currying to the user
return data ? fn( data ) : fn;
};
})();
