I have a form and I would like it to open a new window but with predefined features like width, heigth, etc. I have been trying but no way to pass the variables.

You can apply the Open Window behavior to the submit button and let the follow up page for the form come up in the popup window.

I have already tried this, but it doesn't send the variable. I tried with the onSubmit event too but nothing.

What programming language are you using?

Martha Graham

PHP in the form, Javascript for the Pop Up. Variables should go there via POST.
¿Do U want to see the code?
<script language="JavaScript">
<!--
function MM_openBrWindow(theURL,winName,features) { //v2.0
window.open(theURL,winName,features);
}
//-->
</script>
<form name="referencia" action="ficha.php" target="ficha">
<input type="text" name="varid" class="B">
<input type="button" value="Consultar" onClick="MM_openBrWindow('ficha.php','ficha','scrollbars=yes,width=650,height=550')">
