[c#] How to redirect to action from JavaScript method?

I have an input type="button"

<input type="button" name="DeleteJob" runat="server" value="Löschen" onclick="DeleteJob()" />

and JavaScript method:

function DeleteJob() {

    if (confirm("Do you really want to delete selected job/s?"))
        return true;
    else
        return false;
}

How can I instead return true, redirect to Action DeleteJob?

[HttpGet]
public ActionResult DeleteJob(string selectedObject)
{
    return View();
}

Use the @Url.Action method. This will work and determines the correct route regardless of what IIS server you deploy to.

Example- window.location.href="@Url.Action("Action", "Controller")";

so in the case of the Index action on the Home controller - window.location.href="@Url.Action("Index", "Home")";

(This is more of a comment but I can't comment because of the low reputation, somebody might find these useful)

If you're in sth.com/product and you want to redirect to sth.com/product/index use

window.location.href = "index";

If you want to redirect to sth.com/home

window.location.href = "/home";

and if you want you want to redirect to sth.com/home/index

window.location.href = "/home/index";

I wish that I could just comment on yojimbo87's answer to post this, but I don't have enough reputation to comment yet. It was pointed out that this relative path only works from the root:

        window.location.href = "/{controller}/{action}/{params}";

Just wanted to confirm that you can use @Url.Content to provide the absolute path:

function DeleteJob() {
    if (confirm("Do you really want to delete selected job/s?"))
        window.location.href = '@Url.Content("~/{controller}/{action}/{params}")';
    else
        return false;
}

I struggled with this a little because I wanted to use Knockout to bind the button to the click event. Here's my button and the relevant function from inside my view model.

<a class="btn btn-secondary showBusy" data-bind="click: back">Back to Dashboard</a>

var vm = function () {
...
    self.back = function() {
        window.location.href = '@Url.Action("LicenseDashboard", "Application")';
    }
}

Youcan either send a Ajax request to server or use window.location to that url.

Maybe better to make an anchor with DeleteJob url instead of button?

<a href="<%=Url.Action("DeleteJob", "YourController", new {selectedObject="someObject"})%>" onclick="return DeleteJob()">Löschen</a>

and use your javascript you wrote already:

function DeleteJob() {

        if (confirm("Do you really want to delete selected job/s?"))
            return true;
        else
            return false;
    }

So if function return true - you will be redirected. If function return false - you still stay on the page.

function DeleteJob() {
    if (confirm("Do you really want to delete selected job/s?"))
        window.location.href = "/{controller}/{action}/{params}";
    else
        return false;
}
