Angular指令 - 要求ngModel AND表單^

Question

在一個角度指令中，您可能需要form^AND ngModel？是否可以在鏈接功能中訪問窗體和控制器？

angular.module('myApp') 
.directive('passwordValidation', passwordValidation) 
function passwordValidation(){ 
    return { 
    replace: true, 
    require: 'ngModel', // also 'form^' ? 
    scope: { 
     userName: '@' 
    }, 
    link: function(scope, elem, attr, ctrl, form) { 
    ... 

Answer 1

是的，它可以通過在require屬性中提供一個數組來實現。使用這個，你將在鏈接函數中提供第四個參數的控制器數組。

angular.module('myApp') 
.directive('passwordValidation', passwordValidation) 
function passwordValidation(){ 
    return { 
    replace: true, 
    require: ['ngModel','^form'], // also 'form^' ? 
    scope: { 
     userName: '@' 
    }, 
    link: function(scope, elem, attr, controllers) { 
     var ngModelCtrl = controllers[0],formCtrl = controllers[1]; 
    } 
    }}
