设置为脏数据的字段来触发角JS验证 [英] Setting fields to dirty to trigger validations in Angular JS

问题描述

我想获得的所有字段的形式，并将它们设置脏。

I am trying to get all the fields in a form and set them dirty.

事情是这样的：

 $timeout(function () {

        $('input').each(function(){

             $(this).$dirty=true;

        });
    }, 0);

这是行不通的。我不明白，像这样的作品就好了：

This is not working. I do understand that something like this works just fine:

$scope.form.uName.$dirty = true;

但是，当我使用jQuery在所有领域的循环，不顺心的事。

But when I iterate through all the fields using jquery, something goes wrong.

鸭preciate任何帮助。谢谢。

Appreciate any help. Thank you..

推荐答案

创建一个链接指令函数，通过表单属性迭代。用一根火柴，以免其中含有 $ 去仅表单字段任何形式的对象属性。将 $脏的这些属性真正：

Create a directive with a link function that iterates through the form properties. Use a match to avoid any form object property which contains a $ to get to only the form fields. Set the $dirty property of these to true:

.directive('makeDirty', function(){
    return function(scope, elem, attr) {
        angular.forEach(scope.form, function(val, key){
            if(!key.match(/\$/)) {
                val.$dirty = true;
            }
        });
        scope.form.$setDirty(); // you can make the form itself $dirty if you wish to
    }
});

更新小提琴

这里使用指令的优点在于，直到表格准备好它不会运行链路code;有一些小的重构，也有可能是跨多个表格/控制器重复使用。

The advantage of using a directive here is that it will not run the link code until the form is ready; with some minor refactoring, it could also be reused across multiple forms/controllers.
