我有一個自定義指令,當我一旦改變輸入值,但當我提交表單時不改變輸入字段值指令不顯示錯誤消息。如何調用表單上的自定義指令提交
的html代碼:
<form name="myform" role="form" class="form-horizontal" method="post" novalidate>
<div class="form-group">
<label class="control-label col-sm-3" for="firstName">First name :</label>
<div class="col-sm-9">
<input name='firstName' class="form-control" type='text' required ng-model='name' string>
</div>
</div>
<div class="form-group">
<input type="submit" value="Submit" class="btn btn-success" />
</div>
</form>
指令:
validationModule.directive('string', function() {
return {
restrict: 'A',
require: 'ngModel',
link: function (scope, element, attr, ctrl) {
function validationError(value) {
if (value.length < 1) {
ctrl.$setValidity('required', false);
//showPopOver(element, "Required field");
errorValidation(element, "Required field");
// $(element).popover('show');
}
if (/[a-zA-Z]/.test(value)) {
ctrl.$setValidity('invalid', true);
// $(element).popover('destroy');
successValidation(element);
}
if (/[0-9]/.test(value)) {
ctrl.$setValidity('invalid', false)
errorValidation(element, "number not allowed");
// showPopOver(element, "number not allowed");
// $(element).popover('show');
}
return value;
}
ctrl.$parsers.push(validationError);
}
};
});
我如何可以調用指令對提交事件進行驗證?
