angularJS

Question

用 angularjs 怎么写使得
<span class="assess1"></span>根据某个数字可以显示多次，比如当a等于3就显示三个：
<span class="assess1"></span><span class="assess1"></span><span class="assess1"></span>
等于4就显示<span class="assess1"></span><span class="assess1"></span><span class="assess1"></span><span class="assess1"></span>四个？？？？？？？？？？？？

其实这样也可以：
如果a=4

<span class="assess1" ng-if="a<=1"></span><span class="assess1" ng-if="a<=2"></span><span class="assess1" ng-if="a<=3"></span><span class="assess1" ng-if="a<=4"></span>

这样就显示四次，但是有别的方法吗？觉得这样很麻烦。。。很挫

Answer 1

页面代码如下：

<span class="assess1" ng-repeat="i in getNumberArray(a)">你好</span>

ctroller中定义：

    $scope.getNumberArray = function(number){
      var numberArray = [];

      for (var i = 0; i < number; i++) { 
        numberArray.push(i) 
      } 
      return numberArray;
    }

Answer 2

ng-repeat
