Question

What’s the correct syntax to search a .txt file for a keyword in JavaScript?

EDIT: I’m working with a subset of JavaScript called UnityScript in a program called Unity3D. It outputs .exe programs. Here’s an example of UnityScript:

import System.IO;

function ReadFile () {
    var sr = new StreamReader(Application.dataPath + "/" + readFilePath);
    var fileContents = sr.ReadToEnd();
    sr.Close();

    var lines = fileContents.Split("~"[0]);
    for (line in lines) {
        Debug.Log (line);
    }
}

I thought that if I could get a function from JavaScript I could import it into my program. I see now that perhaps I was wrong.

Try this:

function process(url, send, RegExp) 
{ 
    with(new XMLHttpRequest) { 
        open((send) ? "POST" : "GET", url , false);
        setRequestHeader("Content-Type:","text/Plain");
        send(send);
        if(readyState == 4)
            return RegExp != null ? responseText.match(RegExp) : responseText
    }
}

example

file.txt :

name=frank&id=12&foo=a

Call the function like

process("file.txt", null, /name=([^&]+).id=(\d+)&foo=([^\n]+)/g)
