javascript - 语法错误: Token '<' not a primary expression

Question

当我尝试执行以下操作时，出现以下错误:

https://docs.angularjs.org/error/$parse/syntax?p0=%3C&p1=not%20a%20primary%20expression&p2=7&p3=%7Bleft:%3Cimageid,right:%20%3Eimageid,

Controller :

function MyCtrl($scope) {
    angular.forEach(document.querySelectorAll(".q"), function(val, key) {
        (function(key, val) {
         console.log(val.getAttribute("ng-class").replace(/\{{([ind]+)\}}/g, key));
      })(key, val);

    });
}

.ng-invalid { 
    border: 1px solid red; 
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="">
  <div ng-controller="MyCtrl">
      <div ng-class="{x:{{ind}}<id,y:{{ind}} >id, z :{{ind}} == id}" class="q"></div>
      <div ng-class="{x:{{ind}}<id,y:{{ind}} >id, z :{{ind}} == id}" class="q"></div>
  </div>
</div>

上面的代码在控制台中打印得很好，完美地替换了 {{ind}} 值，但是当应用程序执行时，我收到以下错误:

Syntax Error: Token '<' not a primary expression at column 7 of the expression [{x:id,] starting at [{4}].

我认为 Angular 试图告诉你必须将 div 作为字符串传递。
