problems when using javascript in jsp
[nobr]hello, i am implementing a program to upload files.
a user can upload either a pdf or a latex file.
so for example if the user uploads a pdf file the form action should be
"uploadPDF.jsp" and if it is a latex file the action is "uploadlatex.jsp"
currently when the user uploads the pdf file IT WORKS and does the action correctly but it does not do it for the other file (latex file) gives
some long jasper exceptions pls help
*************here is the code*******************
<SCRIPT LANGUAGE="JavaScript">
var extArray = new Array(".pdf", ".tex", ".txt");
function LimitAttach(form, file) {
allowSubmit = false;
if (!file) return;
while (file.indexOf("\\") != -1)
file = file.slice(file.indexOf("\\") + 1);
ext = file.slice(file.indexOf(".")).toLowerCase();
for (var i = 0; i < extArray.length; i++) {
if (ext = "pdf"){
document.forms[0].action.value = "uploadPDF.jsp";
allowSubmit = true;
break;
}
}
if (allowSubmit) form.submit();
else
alert("Please only upload files that end in types: "
+ (extArray.join(" ")) + "\nPlease select a new "
+ "file to upload and submit again.");
}
</script>
</HEAD>
******************
and below is the form
******************
<form action="" name="upform"enctype="multipart/form-data">
<input type="file" name="PDFfilename" size="50">
<input type="hidden" name="todo" value="upload">
<input type="submit" name="Submit" value="Upload" onclick="LimitAttach(this.form, this.form.PDFfilename.value)">
</form>
