Hi folks,

  I have a page written in php ,

Open in new window

html and some javascript. It works well. I have a preview button in which I want to take the value from a textbox and display it in a child window. My script for popping up the child window works well, I just can't seem to get the value of the textbox passed to the child window.  I have posted the javascript, the html for the textbox and coding from my child window. The value that I am passing is html code. Any help appreciated....

This the textbox control - is placed between form tags.

 <table  align="center">
            <tr><td><textarea id="myhtml" name="supoffers" cols="80" rows="20"></textarea></td></tr>
        </table>

Open in new window

.

This is the javascript that calls the function to open a pop-up child window
<script type="text/javascript" language="javascript">
    var passVariable;
    function mkPreview() 
    
        {
	    var passVariable= document.getElementById("myhtml").value;
	    window.open('preview.html', 'Preview', 'width=600, height=600,left=70, top=70 scrollbars=yes resizable=yes menubar=no');
     }

</script>

Open in new window


This is the code in the child window - its the only code there
<script>
    document.write('opener.passVariable');

</script>

Open in new window
