什么是 document.getElementByName AngularJS 的等价物？
我正在使用 AngularJS 进行表单的编辑部分，并希望在输入中注入(inject)从数据库中获取的值。之后将编辑输入内容并随后执行 ALTER TABLE。
后端使用 PHP。

最佳答案
Amy Blankenship 一针见血，您应该使用 Angular 最强大的功能(如数据绑定(bind))，而不是直接获取元素。
也就是说，如果你真的想这样做，你可以:
angular.element( document.getElementById('someElement') )
关于javascript - AngularJS 中的 GetElementById，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35095656/
