我的 ngMessages 在我的指令模板中不起作用!
我有一个myInput
带有模板和链接函数的指令,在模板函数中,我为包装的<label>
and创建模板字符串<input>
。
在 Link 函数中,我使用require: '^form'
FormController 并检索表单名称。然后我ngMessages
在包装元素之后放置一个块。
(function () {
'use strict';
angular
.module('app.components')
.directive('myInput', MyInput);
/*@ngInject*/
function MyInput($compile, ValidatorService, _, LIST_OF_VALIDATORS) {
return {
require: '^form',
restrict: 'E',
controller: MyInputController,
controllerAs: 'vm',
bindToController: true,
template: TemplateFunction,
scope: {
label: '@',
id: '@',
value: '=',
validateCustom: '&'
},
link: MyInputLink
};
function MyInputController($attrs) {
var vm = this;
vm.value = '';
vm.validateClass = '';
vm.successMessage = '';
vm.errorMessage = '';
}
function TemplateFunction(tElement, tAttrs) {
return '<div class="input-field">' +
' <label id="input_{{vm.id}}_label" for="input_{{vm.id}}" >{{vm.label}}</label>' +
' <input id="input_{{vm.id}}" name="{{vm.id}}" ng-class="vm.validateClass" type="text" ng-model="vm.value" >' +
'</div>';
}
function MyInputLink(scope, element, attrs, form){
var extra = ' <div ng-messages="' + form.$name + '.' + scope.vm.id + '.$error">' +
' <div ng-messages-include="/modules/components/validationMessages.html"></div>' +
' </div>';
$(element).after(extra);
}
}
})();
用法:
<h1>Test</h1>
<form name="myForm">
<my-input label="My Input" id="input1" value="vm.input1"></my-input>
-------
<!-- this block is hardcoded and is working, it does not come from the directive! -->
<div ng-messages="myForm.input1.$error">
<div ng-messages-include="/modules/components/validationMessages.html"></div>
</div>
</form>
