javascript - Angular JS 过滤器不等于

Question

这似乎是一个非常基本的问题，但我无法正确理解语法..

<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 不为 -1 的问题。 我究竟做错了什么。谢谢!

Answer 1

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>

编辑:

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>
