在嵌套指令中传递 ng-model [英] Passing ng-model in nested directives
本文介绍了在嵌套指令中传递 ng-model的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想将我的 ng-model 从外部指令"传递到内部指令"(包含在外部指令模板中).
I want to pass my ng-model from the 'outer-directive' to an 'inner-diretive' (which is contained in the outer-directive template).
正确的做法是什么?
HTML 代码:
<body>
<outer-directive ng-model="prop" />
</body>
和指令代码:
angular.module('app', []).directive('outerDirective', function(){
return {
template: '<inner-directive ng-model="prop" />',
link: function() { ... }
}
});
推荐答案
您可以设置双向绑定(请参阅 documentation, section "Directive Definition Object") 与 ngModel 属性中的变量，与任何其他指令一样:
You can set up a bi-directional binding (see the documentation, section "Directive Definition Object") with the variable in ngModel attribute, as with any other directives:
<my-directive ng-model="foo"></my-directive>
myApp.directive('myDirective', function () {
return {
template: '<div><input type="text" ng-model="ngModel" /></div>',
replace: true,
scope: {
ngModel : '=',
},
};
});
