[英]ng-dialog: input radio button value is undefined
I'm trying to get the radio value button value from ng-dialog but it always got undefined. 我正在尝试从ng-dialog获取单选按钮的值,但始终未定义。
Here is the dialog template: 这是对话框模板:
<script type="text/ng-template" id="flag-reasons.html">
<div style="padding:10px;">
<span>
What's wrong ?
</span>
<div class="form-group" ng-repeat="flagreason in flagreasons">
<input type="radio" ng-model="fr" name="frname" value="{{flagreason.id}}"> {{flagreason.title}}
</div>
<div class="form-group">
<button type="button" ng-click="validFlag()">
Valider
</button>
</div>
</div>
</script>
Here is the partial js where I start with the dialog: 这是我从对话框开始的部分js:
$scope.openFlag = function(){
$scope.dialog = ngDialog.open({ template: 'flag-reasons.html',
className: 'ngdialog-theme-default', scope: $scope });
$scope.validFlag = function(){
console.log($scope.fr);
}
}
I have tried ng-value as below: 我尝试了ng-value,如下所示:
<input type="radio" ng-model="fr" name="frname" ng-value="flagreason.id"> {{flagreason.title}}
but it still got undefined 但它仍然不确定
Notice that it works when I directly set the value of the radio button like: 请注意,当我直接设置单选按钮的值时,它会起作用:
<input type="radio" ng-model="fr" name="frname" value="5"> {{flagreason.title}}
The issue is with ngmodel that's not getting update. 问题是ngmodel无法更新。 You have to initialise ngmodel first in the template.
您必须先在模板中初始化ngmodel。
flag-reasons.html flag-reasons.html
<script type="text/ng-template" id="flag-reasons.html">
<div style="padding:10px;">
<span>
What's wrong ?
</span>
<div class="form-group" ng-repeat="flagreason in flagreasons">
<input type="radio" ng-model="cb.fr" name="frname" value="{{flagreason.id}}">{{flagreason.id}} - {{flagreason.title}}
</div>
<div class="form-group">
<button type="button" ng-click="validFlag()">
Valider
</button>
</div>
</div>
</script>
Controller 控制者
angular.module("app", ['ngDialog'])
.controller('Ctrl',function ($scope, ngDialog) {
'use strict';
$scope.cb = {};
$scope.flagreasons = [
{id: 1, title: 'title1'},
{id: 2, title: 'title2'},
{id: 3, title: 'title3'}
];
$scope.openFlag = function(){
$scope.dialog = ngDialog.open({ template: 'flag-reasons.html',
className: 'ngdialog-theme-default', scope: $scope });
$scope.validFlag = function(){
console.log($scope.fr);
}
}
$scope.$watch('cb.fr', function (v) {
console.log(v);
});
});
