您可以通过手动添加 NG-停用
每个&LT做
标签,但有如果我们使用了办法做到这NG选项
指令在选择标签?
You can do it by manually adding ng-disabled
to each <option>
tag, but is there a way to do it if we are using the ng-options
directive in the select tag?
答
要做到这一点(现在我们已经想通了这个问题)的方法之一是使用放弃 NG-选项
在选择
元素,并与NG-重复添加的选项,那么我们可以添加一个 NG-停用
检查每个选项
。
One way to do this (now that we've figured out the question) is to forgo using ng-options
on the select
element, and add the options in with ng-repeat, then we can add an ng-disabled
check on each option
.
<div ng-app="myapp">
<form ng-controller="ctrl">
<select id="t1" ng-model="curval">
<option ng-repeat="i in options" value="{{i}}" ng-disabled="disabled[i]">{{i}}</option>
</select>
<button ng-click="disabled[curval]=true">disable</button>
</form>
</div>
进行测试的最小控制器:
a minimal controller for testing:
angular.module('myapp',[]).controller("ctrl", function($scope){
$scope.options=['test1','test2','test3','test4','test5'];
$scope.disabled={};
})
