Примечание: предупреждение вы будете получать это length из этой строки

Answer 1

ошибка раис ed, когда Строка узел имеет один элемент внутри.

Я изменил код для преобразования элемента строки в массив, но после исправления ошибки вышли другие, которые я пытался исправить, но я думаю, что они должны быть пересмотрены.

Вот новый код

var myApp = angular.module('myApp', []); 

myApp.controller("MyCtrl", function($scope) {
