Here is my code to validate a file name against blank spaces in an attachment for a sharepoint list.

—————————————-

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 and white spaces from file attachment name.”);
return false;
}
else {
return true;
}
}
————————————-

Its working fine with all browsers except IE. Can you suggest me an aleternate way to fix this?

Is this an issue with the ‘/s’ metacharacter?
