c# - Redirecting to another page in ASP.NET MVC using JavaScript/jQuery

Question

I want to redirect from one page to another page in ASP.NET MVC 3.0 using JavaScript/jQuery/Ajax. On button click event I have written JavaScript code like below.

function foo(id)
{
    $.post('/Branch/Details/' + id);
}

My controller code is like this:

public ViewResult Details(Guid id)
{
     Branch branch = db.Branches.Single(b => b.Id == id);
     return View(branch);
}

When I click on a button it is calling the Details action inside BranchController, but it doesn't return to the Details view.

I didn't get any error or exception. It's showing status 200 OK in Firebug. What is wrong in my code and how can I redirect to the Details view page?

Answer 1

You are not subscribing to any success callback in your $.post AJAX call. Meaning that the request is executed, but you do nothing with the results. If you want to do something useful with the results, try:

$.post('/Branch/Details/' + id, function(result) {
    // Do something with the result like for example inject it into
    // some placeholder and update the DOM.
    // This obviously assumes that your controller action returns
    // a partial view otherwise you will break your markup
});

On the other hand if you want to redirect, you absolutely do not need AJAX. You use AJAX only when you want to stay on the same page and update only a portion of it.

So if you only wanted to redirect the browser:

function foo(id) {
    window.location.href = '/Branch/Details/' + id;
}

As a side note: You should never be hardcoding urls like this. You should always be using url helpers when dealing with urls in an ASP.NET MVC application. So:

function foo(id) {
    var url = '@Url.Action("Details", "Branch", new { id = "__id__" })';
    window.location.href = url.replace('__id__', id);
}
