I am making an Ajax call using Jquery. Sometimes I get error/exception from the back-end. I want to catch them show appropriate error message to the user.

How can I handle exception/error scenarios with Jquery?

The code looks a little something like this:

$.get('url', function() {
    alert("success");
})
.error(function() {
    alert("error");
})

Another snazzy way of dealing with error handling

$.get("url")
.done(function(){ 
    alert("success");
})
.fail(function(){
    alert("error(fail)");
});

You could also use the .ajaxError() method, which involves too much prep work for my taste.

.ajaxError() example:

$(document).ajaxError(function(e, xhr, settings, exception) { 
    alert("error"); 
});

I find that the $.get().error() chaining method is more efficient as it involves the least amount of lines of code. And when you’re working with the mobile web, every line counts.
