So I wanted to create a super small string interpolator for JavaScript. I really didn’t need a full on JS template library. Just a simple helper method that would let me pass an object to a string. You can write a string with “a #{placeholder}” then pass an object to the string with a placeholder key and value..

Example :

"Hi, #{name} you have #{count} credits left".tmpl({name : "John", count : 10});

Of course this is somewhat of a contrived example. However, one can see how useful it becomes when you have a long string that you want to reuse with many records.

I borrowed the placeholder syntax from CoffeeScript/Ruby. I am using forEach so some JS engines will not recognize that as a native Array method. Perhaps someone want to commit a more vanilla loop instead!

I’m interested to see other super powerful prototype helpers developers have created. What’s your favorite?



Sidd, short for Siddhārtha Gautama, is a plug-in for jQuery. It allows you to integrate Zendesk forum posts into your web site/application.


I put most of my initial development into building an extensible & flexible plugin so the demos are a little paltry right now. Here’s a small demo

Configuration Options:


Set the current state to either 0 or 1. This is used for the showMenus method. I suggest leaving it to 0


The URL of your Zendesk. This could be your custom domain, e.g., or just This is a required parameter and no default is set


To save on http requests & increase performance, you can use json method to copy your entire Zendesk forum posts model to a json string to be saved in a local server file. Must have window.JSON support

Methods :


Use the init method first! This will bind all the sidd plugin methods and data to a desired “scope” element In the below example we are using document as our scope, I recommend using a SINGLE element for the scope.

Init Example :

        url : "" 
        // or your mapped domain ""
        //do something


This is your model “getter” method. Use this to filter and return desired Zendesk forum entries saved in $.data(scope).sidd You can filter by any key in forum entry json object! As of 6/2011 that’s [body,created_at,flag_type_id, forum_id, hits, id, is_highlighted, is_locked, is_pinned, is_public, organization_id, pinned_index, position, posts_count, submitter_id, title, updated_at, votes_count], AND!.. dom_tag (more about dom_tags later)

Example :

var data = $(document).sidd("data",{
                current_tags : ["login", "access"],
                forum_id : 23422

A Note about the domtag filter.. This is a wonderful feature! Here’s how it works. You add tags to your Zendesk forum posts like _wrapper, _nav, _my_other_id and so on. The “" prepended tags (optional) represent id’s IN YOUR DOM. Now you have a way to attach zendesk forum data or tooltips to specific parts of your application.

Example :

var data = $(document).sidd("data",{
                         dom_tag : "_"  //or a full id like "_wrapper"

          $.each(data.dom_tags, function(index,selector){

                //get the element by dom_tag
            var el = _this.find(selector+":visible").eq(0), 

                //get the entries containing this dom id
                entries = $.grep(data.filtered,function(obj){
                                return obj.dom_tags.indexOf(selector) !== -1;

Check out the showMenus code to see how the dom_tag filter is used.


This method builds on top of the data method and adds an easy way to perform an action after filtering your posts.

Example :

            body : "password"
    .data("chainable",true); //you can still chain from sidd ;)


This method takes advantage of the “dom_tag” filter. (Read more above under the data method for an in depth explaination.) The showMenus method will create tooltips next to each element with an DOM id that MATCHES a zendesk tag! It’s easiest to understand with a demo.

Example : $(document).sidd(“showMenus”,{dom_id : “_wrapper”});

The above example will… * filter your zendesk entries that have a tag of “_wrapper” * attempt to find $(“#wrapper:visible”) * Create a tooltip containing a menu of forums/entry links with an page offset near the $(“#wrapper:visible”) element!

Note : each menu get’s a class of ‘sidd-menu’. (See the sidd-menu css file for some nice tooltip styling.) However, You can pass your own $(menu) to the showMenus configuration object to be cloned for each tooltip! So you don’t have to use the sidd-menu class.


    dom_id : "_wrapper", 
    menu : $("<div/>",{"class" : "myownClassName", title : "zendesk-help"})


Removes all of the current menus on the page. Currently there is now way to remove only certain items from the menu stack




Toggles the menus in the given scope.




Returns an array of all of sidd’s public methods for easy reference


returns a json string of your entire Zendesk forum model to teh console. The purpose of this is to reduce the number of http requests you make to zendesk upon invoking the init function. The number of requests is based on the number of forums you have.


    //then c&p the output to say sidd.json

    //then init sidd using the local json model file..
            url : "", //you pass the url anyways for menu links
            data : json

    //or you could use localstorage, amplify.js, or lawnchair to save and recover later!

    localstorage["sidd"] = $(document).sidd('json');

    var data = JSON.parse(localstorage["sidd"] || "[]"), 
        config = {url : ""};
    if(data.length !== 0)
        config[data] = data;

It’s a well known jQuery no-no to constantly recall jQuery selectors like so..

    //do something  
//way later in the project  
    //do something      

But, what I consider an even bigger no-no is having all your jQuery collection variables just dumped out right after a .ready() call.

    var $wrapper = $("#wrapper"),           
        $col1 = $wrapper.children("#col1"),             
        $col2 = $wrapper.children("#col2"),             
        $a = $wrapper.find("a.action"); //end so on     

The problem with declaring your collections are…

  • You are making your functions that deeper in the call stack look waaaay up the scope to find the variable you reference.
  • As your project grows so does your need for selectors and this lack of name-spacing makes your declarations VERY confusing.

My favorite way of keeping track of these selectors is by putting them into objects that I then append to the jQuery object. Like this…

    dom : { 
        window : $(window).scroll(doSomthing),          
        rep_grid : $("#rep_grid").click(doSomething),           
        buttons : {                 
            blue : $("").data("off",true),                
            red : $("").data("off",false)          
//Not to far off your Hungarian Notation style you 
//can now use your selectors like this..    
//NOTE: This is just an example. It means nothing. 
//It's just an example...       
    var window_height = $.dom.window.height();      

Perhaps, you don’t like the Java’esque verbose name-spacing syntax that this sort of practice creates. But, I’m confident you will change your mind as your project grows. By the way consider the added benefits of having your selectors in an object. You can use hasOwnProperty, for in loops, etc.

I’m going to be adding some “snapshot” functionality to our web app “WebPDI”. I found these resources useful.
