我有一个指令,它应该更新另一个输入.
但是,我找不到从指令中访问其他输入的ng-model的方法
accessOther指令
angular.module('test', [])
.directive('accessOther', function() {
return {
require: '?ngModel',
link: function(scope, elem, attr, ngModel) {
// ngModel here only refers to the current input
ngModel.$setViewValue('test');
// how to get access/modify another input? (ie. #outside)
}
}
})
.controller('parentController', function() {
var pc = this;
pc.data = {};
})
.controller('nestedController', function() {
});

在下面的代码中,accessOther指令位于#current但正在尝试更改#outside
<body ng-app="test" ng-controller="parentController as pc">
<input type="text" ng-model="pc.data.parent" id="parent" placeholder="parent">
<div ng-controller="nestedController as nc">
<input type="text" ng-model="pc.data.outside" id="outside" placeholder="outside">
<br>
<input type="text" ng-model="pc.data.current" id="current" access-other placeholder="current">
</div>
</body>

另外,是否可以在指令中更改#parent?
请检查工作演示:Plunker。
将其添加到指令中:
scope.$parent.pc.data.outside = 'changed `outside` from directive';
scope.$parent.pc.data.parent = 'changed `parent` from directive';

您可以访问指令范围对象上的parent scopeusing属性。$parent
