Angularjs：$ locationChangeStart

Question

我尝试在next中检查下一个令牌，但我收到了错误：

TypeError: next.localStorage is not a function

APP.JS

.run(function ($rootScope, $location,$log,User) {

     $rootScope.$on("$locationChangeStart", function (event,next, current,jwtHelper) {

         if(next.localStorage("id_token")){

              console.log("true");

         }else{

             console.log("false");
         }
         /* 

    });

AngularJS文档将第二个参数“newUrl”显示为字符串。

https://docs.angularjs.org/api/ng/service/ $位置

  

angularEvent ：对象。合成事件对象。

     

newUrl ：字符串。新网址

     

oldUrl ：string（可选）。之前的网址已被更改。

     

newState ：字符串（可选）。新的历史状态对象

     

oldState ：字符串（可选）。历史状态对象就在它之前   改变了。

您的代码正在尝试执行以下操作：

document.querySelector('button#start').onclick = function()
{
var counter;
var count = 60;
var mod = 0;
var min = 0;
var finalCount;
//var correct = new Audio('sound/tone-beep.mp3');
//var wrong = new Audio('sound/wrong-action.mp3');
this.style.display = "none";
function countDown()
{  mod = count % 60;


 if ( mod == 0 )
 { min = count / 60;
  document.getElementById('timer').innerHTML  = min+':00';
 }
 else
 {
  min = count/ 60;
  sec = count % 60;
  min = Math.floor(min);
  document.getElementById('timer').innerHTML  = (sec < 10)? min+':0'+sec : min+':'+sec;
 }
 count -=1;
   if( count < 0)
  { clearInterval(counter);
    counter = 0;
    count = 0;
    document.getElementById('timer').innerHTML  = '0:00';
    document.querySelector('button#start').style.display = "block";
        if(document.getElementById('final-score'))
        {
            var score = document.getElementById('score').innerHTML;
            var p = document.createElement('p');
            p.innerHTML = score;
            document.getElementById('ex1').appendChild(p);
        }
        else
        {
         var elem = document.createElement('h3');

         var score = document.getElementById('score').innerHTML;

        }
    document.getElementById('score').innerHTML = 0; 
    console.log(counter);

  }
 return count;
}

counter = setInterval(countDown, 1000);

localStorage是一个窗口对象，应该在所有页面之间共享，以便您可以通过以下方式访问它：

if("http://www.app.com/path".localStorage("id_token")){
