IMacro Scripting - How to read a local .txt file using javascript

Question

This is an iMacro tool if you want to automate some web page page visits using javascript.

I want my javascript to read from a local .txt file (not a .cvs file and not very well formatted.) I would like to find in it, probably with a regular expression ..) and based on this reading the script will do some work in IMacros .. (for example, name some website url, etc.)

Do you have any idea how to do this? I do everything local and this is my local browser reading from my local hard drive .. it should somehow be possible .. but how?

Answer 1

, imacros, javascript.js. , javascript indexOf, if. ( txt ): " !"

var load;
load =  "CODE:";
load +=  "set !extract null" + "\n"; 
load +=  "SET !DATASOURCE text.txt" + "\n"; 
load +=  "SET !DATASOURCE_COLUMNS 1" + "\n"; 
load +=  "SET !DATASOURCE_LINE 1" + "\n"; 
load +=  "SET !extract {{!col1}}" + "\n";
iimPlay(load);
var s=iimGetLastExtract(0);
var index=s.indexOf("w");

    do {
        content += res && (res + "\n");
        f = "CODE: "+"\n";
        f += "SET !EXTRACT null" + "\n";

var FileUtils = Components.utils.import("resource://gre/modules/FileUtils.jsm").FileUtils;

FileLocation = "C:\\myFile.txt"

var file   = new FileUtils.File( FileLocation );

// open an input stream from file
var istream = Components.classes["@mozilla.org/network/file-input-stream;1"].createInstance(Components.interfaces.nsIFileInputStream);
istream.init(file, 0x01, 0444, 0);

// read lines into array
var line = {}, lines = [], hasmore;
do {

} while(hasmore);

istream.close();

// do something with read data
alert(lines);
