如何禁用< option> AngularJS ng-options时选择元素的选择? [英] How to disable a <option> of select element when using AngularJS ng-options?

问题描述

当我们在AngularJS中使用ng-options填充options时，是否可以禁用select元素中的option?

Is there a way to disable an option in a select element when we populate options with ng-options in AngularJS?

像这样: http://www.w3schools.com/tags/att_option_disabled.asp

您可以通过在每个<option>标记中添加ng-disabled来做到这一点，但是如果我们在select标记中使用ng-options指令，有没有办法做到这一点?

You can do it by 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?

推荐答案

一种方法是，忘记在select元素上使用ng-options，并在ng-repeat中添加选项，则可以在每个option上添加一个ng-disabled支票.

One way to do this is, to forget using ng-options on the select element, and add the options in with ng-repeat, then you can add a ng-disabled check on each option.

http://jsfiddle.net/97LP2/

<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>

用于测试的最小控制器:

a minimal controller for testing:

angular.module('myapp',[]).controller("ctrl", function($scope){
    $scope.options=['test1','test2','test3','test4','test5'];
    $scope.disabled={};
})
