Form Submit - Prevalidation throws IE off

Background: The website I am working on has a search bar at the top. The user inputs a part code for a product and the website returns information about that product.

So, I have a basic search bar that posts parameters from a H开发者_Python百科TML form into a PHP script, which then does a lookup on a MySQL server to get the Product.

The problem is because some part codes have "#" characters, I have to use Javascript to insert escape characters, otherwise I only get some of the part code in the PHP script.

Example - 123#ABC would be read as 123.

I use a hidden value in the form, which is populated with the Text Box value, modified by the escape() function in Javascript.

This is my code currently, it works in every browser except for IE.

Any help would be much appreciated :)

<script language="jscript">
    function changeTextBox()
    {
        hiddenSearch.value = escape(txtSearch.value);
        formSearch.submit;
    }
</script>

<form id="formSearch" name="Search" action="?page=search" method="post">
    Search by <u>Part Code</u> or <u>Description</u>
    <input id="txtSearch" type="text" size="35">
    <input id="hiddenSearch" name="Search" type="hidden">
    <input name="Submit" onclick='jscript:changeTextBox();' type="submit" value="Submit">
</form>

take a look at changes-- i think there were issues with your javascript.

   <script language="jscript">
        function changeTextBox()
        {
            document.getElementById("hiddenSearch").value = escape(document.getElementById("txtSearch").value);
            this.submit();
        }
    </script>

<form id="formSearch" name="Search" action="?page=search" method="post" onsubmit='changeText()'>
    Search by <u>Part Code</u> or <u>Description</u>
    <input id="txtSearch" type="text" size="35">
    <input id="hiddenSearch" name="Search" type="hidden">
    <input name="Submit"  type="submit" value="Submit">
</form>
