"href"与"href"之间的区别在于和"ng-href"在AngularJS中 [英] Difference between "href" and "ng-href" in AngularJS

问题描述

我同时使用了href和ng-href，但看不到它们之间的区别.

I've used both href and ng-href and I couldn't see the difference between them.

为什么Angular具有ng-href属性，我什么时候应该使用它?

Why does Angular have the ng-href attribute, and when should I use it?

推荐答案

从文档中:

在href属性中使用{{hash}}之类的Angular标记会使链接转到错误的URL(如果用户在Angular有机会将{{hash}}标记替换为其值之前)单击该链接.在Angular替换标记之前，链接将断开，并且很可能会返回404错误. ngHref指令解决了这个问题.

Using Angular markup like {{hash}} in an href attribute will make the link go to the wrong URL if the user clicks it before Angular has a chance to replace the {{hash}} markup with its value. Until Angular replaces the markup the link will be broken and will most likely return a 404 error. The ngHref directive solves this problem.

实际上，您唯一使用它的地方是链接，您需要依赖于Angular提供给DOM的值.如果您不需要该链接的一部分Angular，或者您不打算使用Angular来生成该链接，则不需要使用ngHref.

Effectively, the only place you're using it is for links in which you need to rely on a value provided to the DOM by Angular. If you do not require Angular for a part of that link, or you don't plan on using Angular to generate that link, then you do not need to use ngHref.
