i am using a javascript function found here in ee.

it works nice to retrieve the querystring variables and later write them on the html page

i ran into a problem, and that is, when a passed variables contains a backslash such as:

p_old_path=\\PPT.DFT\Files\Global\My_Directory

the variables is written as

\PPT.DFTFilesGlobalMy_Directory  

how can the function be modified so it escapes the backslashes that are contained on the passed querystring variables?


Thank you.
<script language="javascript">
    p_name= "";
    p_id= "";
    p_old_path= "";
    p_new_path= "";
    p_dir_owner= "";
    p_primary_stew= "";
    p_bckup_stew= "";
    p_full_access= "";
    p_read_access= "";
    p_description= "";
    p_other_info= "";
// Get names
var queryString = window.location.href.substring((window.location.href.indexOf('?') + 1));
var array1 = queryString.split('&'); // Each array element is in format "fieldname=value"
for(var i = 0; i < array1.length; i++)
{
   var tempArray = array1[i].split('='); // Separate fieldname and value
   eval(tempArray[0] + " = \"" + tempArray[1] + "\"");
}
</script>
