I want to count tabs in the start
of lines and create tree levels
$(".importTree").on("change", function(e) {
var file = this.files[0];
var reader = new FileReader();
reader.onload = function(progressEvent){
var tree = this.result.split('n');
var tabLvl = [] ;
for (line in tree) {
tabLvl.push(tree[line].split(/[^t]/)[0].length)
console.log(tabLvl);
};
//after I split file into lines tabs are disappeared
};
reader.readAsText(file);
};
});
after I split file into lines tabs are disappeared
