使用getElementById获取定位标记的对象 [英] Getting object of anchor tag using getElementById

问题描述

anchorobject = document.getElementById('backbutton');
alert(anchorobject);

<a href="http://www.hotmail.com" id="backbutton">back</a>

上面的代码警告href属性字符串(http://www.hotmail.com).不是对象本身.我正在编辑的文件只是一个本地文件，将来我想在某些第三方程序中使用.首先，我正在本地计算机上对其进行编码.当我尝试获取DIV的对象时，效果很好.

The above code alerts the href attribute string (http://www.hotmail.com). Not the object itself. The file I am editing is just a local file which I want to use in some third party program in the future. First, I am coding it on my local computer. When I try to get the object of a DIV it works just fine.

为什么我不能使用document.getElementById()在JavaScript中获得锚点(<a>)标签的对象?

Why can't I get the object of an anchor (<a>) tag in JavaScript using document.getElementById()?

推荐答案

您正在获取锚对象.只是alert是一个非常差的调试解决方案.如果警报锚对象，它将仅显示它为href.请参见此示例.相反，我建议将Firebug或Chrome与console.log一起使用.

You are getting the anchor object. It's just that alert is a very poor debugging solution. If you alert an anchor object, it will just show you it's href. See this example. Instead, I would recommend using Firebug or Chrome with console.log.
