Like others I'd never seen that URL format before. I'm just nervous about 3rd party hosting I guess, particularly with scripts. If they change the script to something malicious, or get hacked by someone else who does, your site is also then wide open for attack. Also if they changed the caching policy they could get all those lovely referrers and google.com cookies. Not that I'm paranoid! *8-} Nice post! Like others I’d never seen that URL format before.

What if we need to do a client side validation using javascript before disabling and posting back the page. I read the comment section where people talk about similar scenario. But what I am asking is different. I cannot have validators but need to write a javascript function which does a initial client side validation. So, say if one of the text box in my form has value greater than certain amount, disable the button and do a post back, else show an error message and not post back? Thank you for the post, but I have a question.

I cant figure out how to solve this problem. The problem i have is, when btnSubmit is clicked, everything is working fine. But when i click btnClear, jquery stops working. This is a simplied version, the actual code has a gridview instead of lblMessage. Also in actual code btnClear is in each row in the gridview.

Just one note, your example won't work properly because you set the updatepanel id to "up1" and then call the postback as "__doPostBack('UpdatePanel1', '');" This way it will cause a full postback, the postback line must be: __doPostBack('up1', ''); Thanks Hi Dave,

thanks for the article, it helped me a lot.

Just one note, your example won’t work properly because you set the updatepanel id to “up1″ and then call the postback as “__doPostBack(‘UpdatePanel1′, ”);”

This way it will cause a full postback, the postback line must be:

__doPostBack(‘up1′, ”);

Thanks

People have been discussing "large JavaScript" development for several years now, and there's not a lot of consensus or "right" approaches. In my projects, using the revealing module pattern and breaking my JavaScript into many files (e.g. project.data.js, project.ui.js, project.ui.slider.js) are two of the most useful tools in keeping the projects manageable. There are MVC frameworks for JavaScript. Backbone is a popular one. However, that's not necessarily something you need to graft into your project if you're still using many ASP.NET pages and a traditional navigation model. Client-side MVC is more targeted to single page applications (e.g. GMail, most of Facebook, new Twitter). That’s a big question.

In order to reliably serve up the latest version for /1 or /1.n, the CDN responds with <em>very</em> short caching expiration headers. So, you lose almost all of the caching benefit. At that point, serving jQuery from your own site with proper caching headers would actually be faster for returning visitors. You shouldn’t do that in production.

Because if a website links to jquery 1.6.0, the other to 1.6.1, the other to 1.6.4 then it will be the same as linking to your server one. So e.g. instead of linking to ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js we should all link to ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js... see the difference? Asap jquery is updated everybody is pointing already to the last version and the caching is there and no need to update your website. Disadvantage: if jquery breaks something you have to correct your scripts or link to an older version. But I would risk that, after all if something stops working then you just link to the older version and voila: fixed.

The keyboard issues are a little troubling, for me that's one of the most important parts to get "right", but like you said one can probably adjust. Great pictures, by the way.
