I just get the parameters from PHP GET method and use them using jQuery. There is no output when run the page.

<?php
    if (isset($_GET['url'])){
        $url = $_GET['url'];
        $url = explode(" " , $url);
        echo end($url);
        exit;
    }
?>
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.js"></script>
<script type="text/javascript">
    $('input[type=text]').change(function (){
        if ($(this).val() !== ''){
            var url = $(this).val():
            $.post('grab.php?url='+url+'', function (data){
                window.open(data, 'Download', 'width=10,height=10');
                $(this).html('');
            });
        }
    });
</script>
</head>
<body>
<input type="text" style="width:100%;height:20px;"/>
</body>
</html>

I’m new to designs and hope mistake is there.

    First of all put your document in standards mode (by using a proper doctype at the beginning, which means HTML 4/XHTML 1 strict or HTML 5). Then you can use error console for debugging.

    I found following error

    Unexpected token: ':' on line 7,

    The colon should be a semicolon.

    var url = $(this).val():

    And then, the actual reason why nothing is happening is because the input is non-existent when the script is invoked/cached. You need to execute it after the DOM has been constructed.

    $(document).ready(function() {
   // content
});

    Final code.

    $(document).ready(function() {
   $('input[type=text]').change(function (){
      if ($(this).val() !== ''){
         var url = $(this).val();
         $.post('grab.php?url='+url+'', function (data){
            window.open(data, 'Download', 'width=10,height=10');
            $(this).html('');
         });
      }
   });   
});
