Question

I have a question relating to the answer on this post Javascript code to parse CSV data

I’m finding I get an extra "\r\n" on the end which I don’t want to add to the array. I’ve tried to break out of the while loop…

The original working line is

 while (arrMatches = objPattern.exec( strData )){

but I need to break out if arrMatches = "\r\n"

while ((arrMatches[ 1 ] != "\\r\\n") && arrMatches = objPattern.exec( strData )){

but get an Invalid left-hand side in assignment error.

What is the correct syntax?

This approach should work, the only thing is that arrMatches should be between ( ) too, to avoid arrMatches being set to true from the second condition.

while ((arrMatches = objPattern.exec( strData )) && (arrMatches[ 1 ] != "\\r\\n")) {
