Compare content from a textfile in javascript

Question

I'm just trying to split textfile data into words and then comparing it but it don't return true.

var contents = e.target.result.split("\n");
if (contents[0] === "abc"])
    alert("abc=abc");

above is the simplest code i am trying to test but even on a single word it gives false. Help

Answer 1

Why you are placed ] in your if condition after "abc"? Remove it

Reference

 if (contents[0] === "abc"])
                          ^

Based on this, I'm assuming you actually want to split your text by whitespace, rather than just unix newlines (\n). If that's the case, try passing a RegExp for one or more consecutive whitespace characters (/\s+/), instead of \n as your separator:

var contents = e.target.result.split(/\s+/);
if (contents[0] === "abc")
    alert("abc=abc");

This will tokenize e.target.result using consecutive whitespace as separators.
