我有一个ng-repeat
创建行,我想定期插入一个新行,但创建它的逻辑在行内并最终弄乱了嵌套,例如:
<tr ng-repeat='item in items'>
<!-- this doesn't work well -->
<tr ng-if='items[$index].day != items[$index-1].day'>
<td colspan=2>
NEW DAY
</td>
</tr>
<td>{{item.name}}</td>
<td>{{item.day}}</td>
</tr>
每当日期发生变化时,我希望数据行中存在“day divider”行。

您可以使用ng-repeat-start和ng-repeat-end,如下所示:
<tr ng-repeat-start="item in items">
<td>{{item.name}}</td>
<td>{{item.day}}</td>
</tr>
<tr ng-repeat-end>
<td>Expand/collapse content</td>
</tr>

在你的控制器中使用新方法如isDivider(item)
会返回bool值。
我没有对此进行测试,但它应该有效:
<tr ng-repeat='item in items'>
<td ng-if="isDivider(item)==true" colspan=2>NEW DAY<td>
<td ng-if="isDivider(item)==false">{{item.name}}</td>
<td ng-if="isDivider(item)==false">{{item.day}}</td>
</tr>

虽然看起来很糟糕,但仍有效:
<tr ng-repeat-start='item in items'>
<tr ng-if='items[$index].day != items[$index-1].day'>
<td colspan=2>
NEW DAY
</td>
</tr>
<td>{{item.name}}</td>
<td>{{item.day}}</td>
</tr>
<!-- dummy row -->
<tr ng-repeat-end></tr>

听起来您可能希望按天分组数据并执行两个嵌套转发器。
angular.module('app', []);
angular.module('app').controller('Ctrl', function($scope) {
$scope.rows = [
{ name: 'one', day: 'monday' },
{ name: 'two', day: 'monday' },
{ name: 'three', day: 'tuesday' },
{ name: 'four', day: 'tuesday' },
{ name: 'five', day: 'thursday' }
];
var groupBy = function(arr, property) { // you can use Underscore instead
var output = {};
for (var i = 0; i < arr.length; i++) {
var item = arr[i];
if (typeof output[item[property]] === 'undefined') {
output[item[property]] = [];
}
if (item.hasOwnProperty(property)) {
output[item[property]].push(item);
}
}
return output;
};
$scope.groupedRows = groupBy($scope.rows, 'day');
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app">
<div ng-controller="Ctrl">
<table>
<!-- it's valid to have more than one tbody -->
<tbody ng-repeat="(key, group) in groupedRows">
<tr>
<th colspan="2">{{key}}</th>
</tr>
<tr ng-repeat="row in group">
<td>{{row.name}}</td>
<td>{{row.day}}</td>
</tr>
</tbody>
</table>
</div>
</div>
注意:如果您希望正确排序分组的行,您可能希望将您的日期存储为整数,并且只更改其显示方式。由于您无法“实际”对对象键进行排序,因此它们会在JS引擎中按字母顺序自动排序,如果它们是数字的,您可以将它们正确排序。

Plz尝试这个
<body ng-app="ngAnimate">
Click me: <input type="checkbox" ng-model="checked" aria-label="Toggle ngHide"><br/>
<div>
Show:
<div class="check-element animate-show" ng-show="checked">
<span class="glyphicon glyphicon-thumbs-up"></span> I show up when your checkbox is checked.
</div>
</div>
<div>
Hide:
<div class="check-element animate-show" ng-hide="checked">
<span class="glyphicon glyphicon-thumbs-down"></span> I hide when your checkbox is checked.
</div>
</div>
</body>

您可以使用repeat-start和repeat-end:
<tr ng-repeat-start="item in items">
<td>{{item.name}}</td>
<td>{{item.day}}</td>
</tr>
<tr ng-repeat-end>
<td colspan="2">
</tr>
