[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;
}
