window.open('url.php?unm=username&pass=password','_blank'); 

but in case don't want display data in url. want use post method data in url.php page.

so how this. please help.. advance

below code use :

$.post("url.php?unm=username&pass=password",function(data){     $("#form").hide(); }); 

you need form submit , open new window

<form id="form" method="post" action="url.php" target="thewindow"> <input type="hidden" name="unm" value="" /> <input type="hidden" name="pass" value="" /> </form> <script> function post(name,password) {   var f = document.getelementbyid('form');   f.unm.value = name;   f.pass.value = password;   window.open('', 'thewindow');   f.submit(); }  post("username","password"); </script>
