HTML and JAVASCRIPT BFS DFS code not working

Hi,

As per your code small changes need to be done.

1. Delete getdata() function and cut paste code outside it. Because onselect of file browse the event need to fire. You are calling this function on button click and trying to access file for this object(var file = this.files[0];). But current object is button, so do you get the file here. So I made delete the function and code will execute on select of file.

2. Secondly I changed the code below for file browse event and same needs to follow for other browse buttons(File2..)

3. It seems you are creating 2-D array in javascript and make sure that 2-D array is same as temp array length.(temp[x][m] = tmp[m];)

Code for File1:

document.getElementById('File1').onchange = function (event) {

var files = event.target.files; //FileList object

for (var i = 0; i < files.length; i++) {

var file = files[i];

var reade = new FileReader();

reade.onload = function (e) {

var textFile = e.target;

var lines = textFile.result.toString().split('\n');

for (var x = 0; x < lines.length; x++) {

var tmp = lines[x].toString().split(' ');

for (var m = 0; m < tmp.length; m++) {

temp[x][m] = tmp[m];

}

};

reade.readAsText(file);

}

};
