Question

我需要一个帮助。我需要使用Angular.js在一个ng-if指令中放入多个条件，但得到以下错误。

Error: [$parse:syntax] Syntax Error: Token '<' not a primary expression at column 87 of the expression [$parent.$parent.$index != 1 && $parent.$index != 0 && $index !=1>
                    <div class=] starting at [<div class=].

我正在解释下面的代码。

 <div ng-if="$parent.$parent.$index != 1 && $parent.$index != 0 && $index !=1>
                        <div class="panel-group accordion-content-div accordioninner accordioninner-inner">
                          <div class="panel panel-default" style="border:1px solid #66afe9;">
                            <div class="panel-heading">
                              <a class="panel-title sky-blue-light auditformpopup" role="button" ng-click="getAllNextPreviousIds(cd.sub_sub_id,$index,$parent.$index,$parent.$parent.$index)">
                              {{cd.des}}

</a>
     </div>

  </div>
</div>

这里我必须使用AND运算符，这里这个div有两个父索引。我需要比较所有这些。请帮我解决这个错误。

据我所知，你刚忘了&& $index !=1>之后的结束双引号（“）
