how to write text field values into a text file before form submission using javascript

Question

I'm new to Java script.

I'm implementing some web pages.
Now, i have TextBox fileds (for users to enter server ip,username and password),upload file button and a Submit button .i want to call a Javascipt script function which takes the values from the textbox and saves it to a .txt file on server before clicking submit button.

Using java script I'm able to read values but when I'm trying to write values into a file, it is not working. When i searched in net i found solution with ActiveXObject which workes only in IE.But I'm looking for the solution which works in all browsers.

My environment supports only javascript and PHP.

Please help me..

<form id="addnew">
    <input type="text" class="id">
    <input type="text" class="content">
    <input type="submit" value="Add">
</form>
<script>
    jQuery(function($) {
        $('#form_addjts').submit(function(){
            writeToFile({
                id: $(this).find('.id').val(), 
                content: $(this).find('.content').val()
            });
            return false;
        }); 
        function writeToFile(data){
            var fso = new ActiveXObject("Scripting.FileSystemObject");
            var fh = fso.OpenTextFile("D:\\data.txt", 8);
            fh.WriteLine(data.id + ',' + data.content);
            fh.Close(); 
        } 
    }); 
</script>
