Sample code in angularjs, to read and write text file - angularjs

Question

I am completely new to this.The solutions that I am getting from internet is reading the file and displaying as it is, but I want to read the file line by line.

Answer 1

var lines = this.result.split('\n');
for(var line = 0; line < lines.length; line++){
console.log(lines[line]); }
with \n you can split a file at his linebreaks.
Your question was very vague but this is the solution when you want to output a file line by line.
To get this into Context:
First we need to input a file, we can achieve this via HTML:
<input type="file" name="file" id="filename">
Now create a js function to grab this file:
document.getElementById('filename').onchange = function(){
// declare file variable
var filevar = this.files[0];
//the Reader:
var datareader = new FileReader();
reader.onload = function(progressEvent){
};
I already included a FileReader, as you can see
Now you can combine this to a full function:
document.getElementById('filename').onchange = function(){
var filevar = this.files[0];
var datareader = new FileReader();
reader.onload = function(progressEvent){
var lines = this.result.split('\n');
for(var line = 0; line < lines.length; line++){
console.log(lines[line]);
}
};
datareader.readAsText(filevar);
};
This is a bit tutorialish so sry, but i guess it helps more then just Code.
