如果此值是对象而不是字符串,如何设置无线电的默认值?
编辑:
为了使事情更清楚,我更新了小提琴:
看看小提琴:

<body ng-app="app">
<div ng-controller='controller'>
oConfigTerminal value= <input type="text" ng-model="oConfigTerminal"/><br><br>
<div ng-show="!oConnection.aOptions"
ng-repeat="oConnection in oFormOptions.aStationaryConnections">
<label>
<input type="radio" name="connection" ng-model="$parent.oConfigTerminal" value="{{oConnection.id}}"
/>{{oConnection.sId}}</label>
</div>
</div>
app = angular.module('app', []);
app.controller('controller', function ($scope) {
$scope.oFormOptions = {};
$scope.oConfigTerminal=0;
$scope.oFormOptions.aStationaryConnections = [{
id: 1,
sId: "analog"
}, {
id: 2,
sId: "isdn"
}, {
id: 3,
sId: "dsl"
}];
// !!! Trying to set the default checked/selected value !!!
$scope.oConfigTerminal = $scope.oFormOptions.aStationaryConnections[0];
});
最佳答案 在浏览器控制台中检查实时html,您将看到oConnection是一个对象,无线电的值变为:{“id”:1,“sId”:“analog”}.您可能希望使用oConnection.id作为值
ng-repeat中的另一个问题是,通过将ng-model设置为$parent.variableName,需要为ng-model解决范围继承问题
您的oConnectionTmpView对我没有任何意义,因此为了简化我将其删除:
HTML:
<div ng-show="!oConnection.aOptions" ng-repeat="oConnection in oFormOptions.aStationaryConnections">
<label>
<input type="radio"
name="connection"
ng-model="$parent.oConfigTerminal"
value="{{oConnection.id}}"
/>
{{oConnection.sId}}
</label>
</div>
JS:
app = angular.module('app', []);
app.controller('controller', function ($scope) {
$scope.oFormOptions = {};
$scope.oConfigTerminal = 0;
$scope.oFormOptions.aStationaryConnections = [{
id: 1,
sId: "analog"
}, {
id: 2,
sId: "isdn"
}, {
id: 3,
sId: "dsl"
}];
}
