角度指令演示：
<div ng-app="myApp">
<script>
function Contrl($scope){
$scope.parval = 0;
$scope.items = [
{id: 1,text: '1'},{id: 2,text: '2'},{id: 3,text: '3'}
];
}
</script>
<div ng-controller="Contrl">
A: <input type="radio" value="1" ng-model="parval">1</input>
<input type="radio" value="2" ng-model="parval">2</input>
<input type="radio" value="3" ng-model="parval">3</input>
<item parval="parval" items="items"></item>
</div>
angular.module('myApp',[])
.directive('item',function() {
return {
restrict: 'E',replace: true,scope: {
parval: '=',items: '='
},template: '<div>' +
'B: <span ng-repeat="i in items">' +
'<input value="{{i.id}}" type="radio" ng-model="parval">{{i.text}}</input> ' +
'</span>' +
'</div>'
};
});
现在：
点击A1 – > B1选中
点击A2 – > B2选中
点击B1 – > A1没变
点击B2 – > A2没变
我想要：
点击A1 – > B1选中
点击A2 – > B2选中
点击B1 – > A1选中了
点击B2 – > A2选中
怎么样？
你正在使用原语,你应该避免使用文字表示法,因为ng-repeat创建了一个新的范围.以下代码将解决您的问题
<div ng-controller="Contrl">
A: <input type="radio" value="1" ng-model="parval.value">1</input>
<input type="radio" value="2" ng-model="parval.value">2</input>
<input type="radio" value="3" ng-model="parval.value">3</input>
<item parval="parval" items="items"></item>
</div>
<script>
function Contrl($scope) {
$scope.parval = { value: 0 };
$scope.items = [
{ id: 1,text: '1' },{ id: 2,text: '2' },{ id: 3,text: '3' }
];
}
angular.module('myApp',function () {
return {
restrict: 'E',template: '<div>' +
'B: <span ng-repeat="i in items">' +
'<input value="{{i.id}}" type="radio" ng-model="parval.value">{{i.text}}</input> ' +
'</span>' +
'</div>'
};
});
</script>
