如何使用 angularJS 中选项的自定义值重置 select 中的 selected 选项

How to reset selected options in select with custom value for options in angularJS

我想用 angularJS 选项的自定义值重置 select 选项 select :

HTML

<select id="" name="" class="form-control" ng-model="mymodel">
    <option value="1000">All</option>
    <option value="-1">Not Done Yet</option>
    <option value="0">Already Done</option>
    <option value="1">Other option1</option>
    <option value="2">Other option1</option>
</select>

Select 选项是:<span>{{mymodel}}</span>

<button class="btn btn-danger glyphicon glyphicon-refresh"
    data-toggle="tooltip" title="Reset"
    ng-click="clearSearch();">Reset</button>

JS

$scope.clearSearch = function () {
    $scope.mymodel = 1000;
}

我让这个工作正常 JSFiddle。好像还不错。

请注意,我初始化了 $scope.mymodel

JS

var myApp = angular.module('myApp',[]);

function MyCtrl($scope) {
    $scope.mymodel = 1000;
    $scope.clearSearch = function () {
       $scope.mymodel = 1000;
    }
}

如果您使用的是 AngularJS 1.4,则需要将值设置为 字符串 而不是数字。

$scope.clearSearch = function () {
    //Use a string
    $scope.mymodel = '1000';
    //Not a number
    //$scope.mymodel = 1000;
}
