Angular JS 过滤器不等于 [英] Angular JS filter not equals

问题描述

似乎是一个非常基本的问题，但我的语法不正确..

Seems like a very basic question but I can't get the syntax right..

<li class="list-group-item" ng-repeat="question in newSection.Questions | filter:Id != '-1'; " ng-mouseenter="hover = true" ng-mouseleave="hover = false">
    <div href="#" editable-text="question.Text">{{question.Text}}</div>
</li>

我只想显示所有 id 不是 -1 的问题.我究竟做错了什么.谢谢！

All I want is to show all the questions where id is NOT -1. What am I doing wrong. Thanks!

推荐答案

语法有点不对，试试:

<li class="list-group-item"
    ng-repeat="question in newSection.Questions | filter:{ Id: '!-1'}"
    ng-mouseenter="hover = true" ng-mouseleave="hover = false">

    <div href="#" editable-text="question.Text">{{question.Text}}</div>
</li>

变量示例:

<script> var invalidId = '-1'; </script>
<li class="list-group-item"
    ng-repeat="question in newSection.Questions | filter:{ Id: '!' + invalidId}"
    ng-mouseenter="hover = true" ng-mouseleave="hover = false">

    <div href="#" editable-text="question.Text">{{question.Text}}</div>
</li>
