如何在不输入任何字段的情况下触发角度解析器 [英] how to trigger angular parsers without inputing anything in the field

问题描述

如主题所述，我如何触发在 a 内发生的动作

As the subject states, how do I trigger the actions to take place inside a

modelController.$parsers(...) 

没有用户输入......我能想到的唯一方法是将它们包装在一个函数中并调用它，但是有没有更好的方法来触发

without user input... the only way I can think of is wrapping them inside a function and call it, but is there a better way to trigger

**//pseudo
$(modelController).trigger('just got dirty');**

我需要它的原因是触发输入字段以在提交页面上验证自身.

the reason I would need this is to trigger the input field to validate itself on submitting page.

推荐答案

我找到了解决这个问题的方法 - 只需使用模型值调用解析器:

I have found a way to solve this - just call the parsers with the model value:

angular.forEach(ngModel.$parsers, function (parser) {
    parser(ngModel.$viewValue);
});

就是这么简单，而且似乎是最正确的解决方案.

It`s so simple, and it seems to be the most correct solution.
