Angular.js 以编程方式将表单字段设置为脏 [英] Angular.js programmatically setting a form field to dirty

问题描述

我正在以编程方式使用值更新表单上的某些字段，并且我想将字段状态设置为 $dirty.做类似的事情:

I am programmatically updating some of the fields on my form with a value and I would like to set the field state to $dirty. Doing something like:

$scope.myForm.username.$dirty = true; 似乎不起作用.

有一种方法 $setPristine 可以用来重置字段的状态，但没有 $setDirty 方法?

There is a method $setPristine that I can use to reset the state of the field but there isn't a $setDirty method?

那么如何去做呢?

我看到了这篇文章https://groups.google.com/forum/#!topic/angular/NQKGAFlsln4 但我似乎找不到 $setDirty 方法.我使用的是 Angular 1.1.5 版.

I saw this post https://groups.google.com/forum/#!topic/angular/NQKGAFlsln4 but I can't seem to find the $setDirty method. I am using Angular version 1.1.5.

推荐答案

从 AngularJS 1.3.4 开始，您可以在字段上使用 $setDirty() (来源).例如，对于每个有错误并标记为必填的字段，您可以执行以下操作:

Since AngularJS 1.3.4 you can use $setDirty() on fields (source). For example, for each field with error and marked required you can do the following:

angular.forEach($scope.form.$error.required, function(field) {
    field.$setDirty();
});
