所需的指令顯示紅色的錯誤消息,工作! uniqueschoolclassnumberValidator指令不顯示紅色錯誤消息!錯誤消息與AsyncValidator不可見
從服務器我總是返回exists => true,但我也試着用false。
我該怎麼做?自定義指令肯定會觸發!
指令
'use strict';
angular.module('TGB').directive('uniqueschoolclassnumberValidator', function (schoolclassCodeService) {
return {
restrict: 'A',
require: 'ngModel',
link: function (scope, element, attrs, ngModel) {
ngModel.$asyncValidators.unique = function (schoolclass) {
var schoolclassNumber = "0a";
var schoolyearId = 1;
return schoolclassCodeService.exists(schoolyearId, schoolclassNumber);
};
}
};
});
服務
this.exists = function (schoolyearId, schoolclassNumber) {
var path = 'api/schoolyears/' + schoolyearId + '/schoolclasses/' + schoolclassNumber;
return $http.get(path).then(function (response) {
if (response.data == true) {
$q.reject("schoolclass number has already been taken");
}
else {
return $q.resolve();
}
});
};
的Html
<form name="myForm">
<div class="col-sm-8">
<input type="text" unique-schoolclasnumber-Validator name="myInput"
ng-model-options="{ updateOn: 'default blur', debounce: {'default': 300, 'blur': 0} }"
ng-model="schoolclassNumber" class="form-control"
required placeholder="Enter schoolclass">
</div>
<div ng-messages="myForm.myInput.$error" style="color:red" role="alert">
<div ng-message="required">You did not enter anything.</div>
<div ng-message="unique">That schoolclass number already exists.</div>
</div>
</form>
拼寫錯誤來自我在這裏所做的複製/粘貼錯誤。但該死的是,返回失蹤,我剛剛沒有看到它!現在它工作了! – HelloWorld
