问题描述
我知道表单元素有一个$ setPristine()函数，如果我想将single设置为ng-pristine单元素标签(如<input>)，是否有一个等效项?
I know there is a $setPristine() function for the form element, is there an equivalent if I want single to set to ng-pristine single element tags like <input>?
推荐答案
原始的概念适用于整个形式，而不适用于单个元素.原始形式是尚未更改的形式，而脏形式是已更改的形式.没有将与表单无关的输入元素标记为原始的语义，对于表单中的输入元素，原始标志仅适用于表单.
The concept of pristine applies to a form as a whole and not to individual elements. A pristine form is one which has not yet been modified while a dirty form is one that has been changed. There are no semantics of flagging a input element unrelated to a form as pristine and for input elements in a form, the pristine flag applies solely to the form.
