Hi Shankar,

I can think of using "Promises".

developer.mozilla.org/en-US/docs/Web/JavaScript/R… http://spion.github.io/promise-nuggets/ http://bluebirdjs.com/docs/getting-started.html

The code would look like.

call1()
.then( val => {
return call2();
})
.then(val => {
return call 3();
})
.then(val => {
//the end
})

I wrote an article on sequential task execution (using promises) in 2013. Take a look.

If you are using Nodejs, You can use Fibers and make it sequential. Looks much more elegant. If not, you can use this plugin!!! http://foliotek.github.io/AjaxQ/

Make the second AJAX call inside the callback of the first AJAX call.
