我的数据基本上归结为:
function ExampleCtrl($scope) {
$scope.myData= [
{text: "blah", other: 3, V: 'caseOne'},
{text: "blah", other: 3, V: 'caseTwo'},
{text: "blah", other: 3, V: 'caseThree'}
];
}
这是这样使用的:
<div ng-controller="ExmapleCtrl">
<table>
<tr>
<td>Text</td>
<td>Other</td>
<td>V</td>
</tr>
<tr ng-repeat="data in myData">
<td><a href="#">{{data.text}}</a></td>
<td>{{data.other}}</td>
<td ng-switch on="data.V">
<td ng-switch-when="caseOne"><img src="assets/img/pass.png"/></td>
<td ng-switch-when="caseTwo"><img src="assets/img/pass.png"/></td>
<td ng-switch-when="caseThree"><img src="assets/img/fail.png"/></td>
</td>
</table>
</div>
问题是我收到此错误:
Error: No controller: ngSwitch..
我清楚地将控制器设置为ExampleCtrl,我没有看到任何输入错误,所以我很遗憾。

我认为问题与产生无效标记的ng-switch
有关。我不确定您是否可以将td
嵌套在另一个td
中。无论如何,如果你改成它,它将起作用:
<td ng-switch on="data.V">
<img src="assets/img/pass.png" ng-switch-when="caseOne"/>
<img src="assets/img/pass.png" ng-switch-when="caseTwo"/>
<img ng-switch-when="caseThree" src="assets/img/fail.png"/>
</td>
这是一个有效的演示:http://plnkr.co/edit/zUdkJYfnlJul6HsyCGfZ
我会继续并建议一些不使用可能更好的开关的解决方案。查看最后两个td
的
<tr ng-repeat="data in myData">
<td><a href="#">{{data.text}}</a></td>
<td>{{data.other}}</td>
<td>
<img src='assets/img/{{data.V}}.png' /> <!-- assuming you have an image with name caseOne.png/caseTwo.png/etc -->
</td>
<td>
<img src='{{passFail[data.V]}}' /> <!-- transform the case stuff to pass/fail based on some business rules, this is an object but could be a function-->
</td>
</tr>
$scope.passFail = {
'caseOne' : 'assets/img/pass.png',
'caseTwo' : 'assets/img/pass.png',
'caseThree' : 'assets/img/fail.png'
};

上述答案的附加内容 如果在td中只有纯文本,如switch case用户角色或其他东西,你可以在td中添加一个span标签来包含文本
<td ng-switch="role">
<span ng-switch-when="1">Administrator</span>
<span ng-switch-when="2">Moderator</span>
</td>
