Hi, I have these 3 codes That read txt files
<!DOCTYPE HTML>

var regex = /^([a-zA-Z0-9\s_\\.\-:])+(.csv|.txt)$/;
if (regex.test($("#fileUpload").val().toLowerCase())) {
if (typeof (FileReader) != "undefined") {
var reader = new FileReader();
reader.onload = function (e) {

$("#dvCSV").append(table);

</body>
</html>These 3 code work perfectly, I want to execute the select file executing automatic file in onload or any other form since it automatically runs in index.html and already open the file data.txt,
Data.txt file and the following
1
2
3
The variable var1 = first line of the data.txt file
Var2 second line of file data.txt
Var3 third line of data.txt file
How could I do that ???
