Spring MVC - redirect with jQuery

问题

I am making an AJAX call to a controller, and I want to redirect to a new page on Success. So I have have the redirection logic within my success callback function. But it doesn't redirect to a new page instead it stays on the same page.

The intriguing thing is that a GET Request (with the form Data I just sent via POST) is made after the Ajax Callback is executed. that is, I see a GET Request in the Address Bar.

Here is my AJAX request

$.ajax({
        url: "processData",
        type: "POST",
        dataType: 'json',
        contentType:'application/json',
        async: false,
        data: JSON.stringify(req),
        success: function(result) {
            url = window.location.href;
            url = url.replace("processData", "getMoreData");
            alert(url); // correct url is printed
            window.location.replace(url);
        },
        error: function() {
            alert("--- Failure ---");
        }
    });

What's wrong in here?

回答1:

And what is wrong with

window.location.href='some url';

That is one thing. Another one - You should remove 'spring-mvc' tag from the question because it is not actually Spring-related.

The answer posted by @Chlebik above is correct. The main issue I was facing was that both GET & POST requests were getting generated. So sometimes the GET request was going forward & the POST request was getting cancelled. Other times the reverse was happening & I was getting correct result.

All I had to do was to avoid the GET request, from the default form's Submit button, from getting generated.

Here's the code for that:

$('form').on('submit', function(e) {
    e.preventDefault();
