[removed].href not working in form onsubmit

Question

So i have a form, and onsubmit=\"return reg_check(this)\" where reg_check() is a javascript function in the header which is supposed to check the f

Answer 1

You need to return false; from your reg_check function and then in your onsubmit, change it to:

onsubmit="return reg_check(this);"

This will cancel the form submission. And if you want to let the form submit as normal, just return true from reg_check.

Edit (to be more clear you need to add return false; from your function):

function reg_check(myForm) {
    alert("before redirect..");
    window.location.href = "http://localhost/main.php?width=" + screen.width + "&height=" + screen.height;
    return false;
}

[RESOLVED] I had a similar problem in redirecting to some other url from client script. Implemented window.open function instead and it worked. You may have for instance, a function say ChangeCity() for your html control event that gets called with onchange event.

function ChangeCity() {
    switch ($("#currentCity").val()) {
        case "NY":
              var url = '@Url.Action("New York City", "Home", new { @area = "" },Request.Url.Scheme)';
            window.location.href = url;
            window.open(url,"_top");
            return false;

/* cases for other cities */

    }

I've seen problems in IE where I've had to do the following:

window.location.assign(url);

Specifically within a jQuery AJAX success handler. Can't really speculate to why other than for me, it worked.

Actually I did

window.location.replace(url)

Which replaces the current page in the history. Nice trick that!

I had the same problem, but found the answer here Javascript: window.location.href doesn't redirect when calling function within a function . My button was reloading the page by default so if you add an

 event.PreventDefault();

To your function it should work.
