    onsubmit="setTimeout(function () { window.location.reload(); }, 10)">
 <div class="form-group">
 <label for="email">E-mailadres</label>
 <input type="email" name="email" class="form-control" id="email">

</div> 
<input type="submit" value="verzenden" class="btn btn-  primary" />
</form>

I want that if someone clicks on the button, he/she will redirect to gmail.com I try target blank, but it doesn't work, does someone know a good manner to redirect with javascript or php?

Answer 1

Try

<input type="button" value="verzenden" class="btn btn-  primary"  onclick="move_to_gmail();"/>


<script>
function move_to_gmail(){
window.location = 'http://www.gmail.com';
}
</script>

Answer 2

with PHP, you could use

header('Location: http://www.example.com/');

and with JavaScript, use

document.location.href="http://www.example.com";

I agree that this scenario is a bit strange as I have no idea what you're actually trying to accomplish but, if you just want to open gmail.com in a new window when the form is submitted, this should suffice:

<form onsubmit="window.open('http://gmail.com')">
    <div class="form-group">
        <label for="email">E-mailadres</label>
        <input type="email" name="email" class="form-control" id="email">
    </div> 

    <input type="submit" value="verzenden" class="btn btn-  primary" />
</form>

Answer 4

To open a new window (if it's really a new window or a new tab is decided by the browser, you can't influence this), use window.open() :

<form id="form1" name="form1" method="post" action="http://gmail.com"       
    onsubmit="window.open('http://gmail.com');return false;">

window.open('http://gmail.com'); opens gmail.com, return false; cancels the submitting of the form. This won't send the data from the form to gmail.com! Demo: http://jsfiddle.net/30d6em13/

Without JavaScript use target="_blank"

<form id="form1" name="form1" method="post" target="_blank" action="http://gmail.com">

This will open http://gmail.com in a new window/tab. But this will send the data entered into the form to gmail.com! Demo: http://jsfiddle.net/30d6em13/1/
