Javascript file name white space validation for a sharepoint attachment

[sijojohn]

Hi,

I want to validate my file name for whitespace before attaching it to a sharepoint list. Here is my code

<Script type="text/javascript"> 
function PreSaveAction() 
{ 
var attachment; 
var filename=""; 
var fileNameSpecialCharacters = new RegExp("\\s", "g"); 
try { 
attachment = document.getElementById("idAttachmentsTable").getElementsByTagName("span")[0].firstChild; 
filename = attachment.data; 
} 
catch (e) { 
} 
if (fileNameSpecialCharacters.test(filename)) { 
alert("Please remove the special characters from the file attachment name.");
return false; 
} 
else { 
return true; 
} 
} 
</script>

This script is working fine with chrome, FF, But this script is blocking all files in IE 7. This script will work fine if I use it to validate special characters only

var fileNameSpecialCharacters = new RegExp("[~#%&*{}<>;?/+|\"]");
 

Not sure whats wrong with white space regExp in IE.

Can anybody help?

BR,

Double check that the file name doesn't somehow have spaces in IE by watching the filename variable.

Post the HTML for the first span in "attachmentsTable".
