如何让角度$ asyncValidator在模糊时触发但在输入时使用常规验证器 [英] How to let angular $asyncValidator fire on blur but normal validators on input

问题描述

是否可以让有角度的1.3 $ asyncValidators仅在模糊时触发，而不是在用户输入时触发?我希望$ validators表现为默认值.

Is it possible to let angular 1.3 $asyncValidators only fire on blur and not as the user inputs? I want the $validators to behave as per default.

我知道我可以使用 ng-model-options 来更新onBlur模型，但是所有验证都会在模糊时触发.

I know I can use ng-model-options to update the model onBlur but then all validations are fired on blur.

推荐答案

当前(angularjs版本1.3)尚无机制可以做到这一点.

Currently (angularjs version 1.3) there is no mechanism to do this.

最后，我添加了一个模糊事件来触发验证器，然后设置有效性

In the end I added a blur event to fire the validators and then set the validity

element.on('blur', function () {
    if (ngModel.$dirty) {
        doServerSideValidation();
    } else {
        ngModel.$setValidity(key, true);
    }
});

doServerSideValidation()函数将在执行请求后设置 ngModel 的有效性.

The doServerSideValidation() function will set the validity of the ngModel after doing the request.
