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

i new this.the solutions getting internet reading file , displaying is, want read file line line.

var lines = this.result.split('\n'); for(var line = 0; line < lines.length; line++){ console.log(lines[line]); } 

with \n can split file @ linebreaks.
question vague solution when want output file line line.
context:
first need input file, can achieve via html:

<input type="file" name="file" id="filename">  

now create js function grab 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 included filereader, can see
can combine 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 bit tutorialish sry, guess helps more code.
