当点击提交按钮时，用javascript或php到gmail.com redirict

Question

I've this form:

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

EDIT: I want that if someone hit the button he/she will redirect to a new tab.

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>
