jQuery Template Sample
This code sample demonstrates how to use jQuery Template Plugin on the Force.com platform. This sample uses a SOQL query to select user data. The rendered template is switched onclick to an editable row. The updates are then persisted back to salesforce using the .update() javascript method.

Developing on Salesforce
I’ve had a healthy amount of exposure to the Salesforce.com platform from an integration standpoint, and I’ve done some tinkering with the web front-end and eclipse IDE in the past, but recently I’ve been involved in a project that’s going to be developed directly on the SFDC platform. Here are some of my initial thoughts on it…

jQuery Combobox
Jörn Zaefferer writes a good summary about creating a jQuery Widget: A jQuery UI Combobox: Under the hood, which was the basis of this official autocomplete demo.
Some customizations I made from here include:
- Automatically open menu on focus-in, which can also allowed for removal of the button (this needs a little UX feedback from our customers.)

1/26/2011 Update
The majority of my work the last few weeks has been HTML + JQuery + JSON… once work calms down a bit, these are some things I want to share:
- Extending an html select with a jquery autocomplete widget, including some UX considerations.
- Using Jquery $.data() to tag data to a DOM element.
- Reposting JSON data to a server, after it was rendered with jQuery Templates.
- Updating a jQuery Template by updating its underlying JSON data, its easy, and you should use it to save on expensive postbacks.
Have fun in the snow.

Tip: stringify your cookies
This simple example shows how you can stringify a simple array to store search history in a cookie, but the same principle can be used for complex data too.

JSON postbacks with MVC
Complex JSON post data was possible with MVC2, but it comes out of the box with MVC3, and it couldn’t be much easier. This code sample should sum it all up, you’ll just need the json2.js library, which gives you JSON.stringify(), and JSON.parse().

jQuery Template Helper with Error Handling
In an effort to clean up some of our ajax code, I wrote a helper to load json from a given url (using http get), render a template with the data, and invoke a callback. The nice part about the helper is that it wraps the error handler (something a simple $.get() doesn’t give you access to.)

jQuery Template - $index Patch
This git branch shows a simple change to the jQuery Template tmpl() function to add an $index property to the dataItem.
Usage:
<!— jQuery UI Tabs —>
<script id=”tabTemplate” type=”text/x-jquery-tmpl”>
<div id=“tab-${$index + 1}”>
<!— render tab contents here… —>
</div>
</script>

Posting JSON to an MVC2 Controller
Good post I came across the other day on how to post JSON data to an MVC2 controller. Also, just noticed the modification to the JsonModelBinder someone posted in the comments that I want to pull into my project today.
