Newbie request: I’d like to modify a line of code that evaluates whether a file is of correct type or not:
onChange="TestFileType(this.form.Resume.value, ['doc', 'zip', 'pdf', 'txt'])"
function TestFileType( fileName, fileTypes ) {
if (!fileName) {
return;
}
fileName = fileName.toLowerCase(); // Convert extension to lowercase
dots = fileName.split(".");
//get the part AFTER the LAST period.
fileType = "." + dots[dots.length-1];
return fileTypes.join(".").indexOf(fileType) != -1?alert('That file type is acceptable'):alert("Please only upload files of these types:
" + fileTypes.join(" .") + "
Replace spaces with undesrcores \"_\" or hyphens \"-\", and remove special characters from the file name.");
}
I only want the alert to show if the file type is incorrect, not if there are no problems with the file type. Thanks for your help.
