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>
