篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了AngularJS - ng-repeat只显示一次标题相关的知识,希望对你有一定的参考价值。
我有2个列表(persons
和animals
),我用ng-repeat
显示。我想在一个带有标题的表中显示这两个列表。以下是我想要显示数据的示例。我已经用ng-show="$first"
尝试过了,但这不是我想要实现的结果。
<thead>
<tr>
<th>ID</th>
<th>BIRTHDAY</th>
<th>NAME</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="ps in $ctrl.persons" ng-if="$ctrl.valuePersons == true">
<th ng-show="$first">PERSONS</th>
<td>{{ ps.id }}</td>
<td>{{ ps.birthday | date: 'dd.MM.yyyy'}}</td>
<td>{{ ps.name }}</td>
</tr>
<tr ng-repeat="an in $ctrl.animals" ng-if="$ctrl.valueAnimals == true">
<th ng-show="$first">ANIMALS</th>
<td>{{ an.id }}</td>
<td>{{ an.birthday | date: 'dd.MM.yyyy'}}</td>
<td>{{ an.name }}</td>
</tr>
<tbody>
答案
根据ng-repeat的文档,这将有效。
...
<tr ng-repeat-start="ps in $ctrl.persons" ng-if="$ctrl.valuePersons == true && $first">
<th>PERSONS</th>
<td></td>
<td></td>
</tr>
<tr ng-repeat-end ng-if="$ctrl.valuePersons == true && !$first">
<td>{{ ps.id }}</td>
<td>{{ ps.birthday | date: 'dd.MM.yyyy'}}</td>
<td>{{ ps.name }}</td>
</tr>
...

另一答案
var app = angular.module("Profile", [] );
app.controller("ProfileCtrl", function($scope) {
$scope.items = [{'title':'PERSON','data':[{'birth_day':'1/1/2011','name':'a1'},{'birth_day':'1/1/2011','name':'a2'},{'birth_day':'1/1/2011','name':'a3'}]},{'title':'ANIMALS','data':[{'birth_day':'1/1/2011','name':'a1'},{'birth_day':'1/1/2011','name':'a2'},{'birth_day':'1/1/2011','name':'a3'}]}]
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="Profile" ng-controller="ProfileCtrl">
<table class="table" border="1">
<thead>
<tr>

<th>BIRTHDAY</th>
<th>Name</thu>
</tr>
</thead>
<tbody>
<tr ng-repeat-start="item in items" ng-init="main_ind= $index">

<tr ng-repeat-end ng-repeat="val in item['data']">
