Javascript 如何显示HTMLpropertiescollection(toString/object属性)

Javascript 如何显示HTMLpropertiescollection(toString/object属性),javascript,jquery,dom,Javascript,Jquery,Dom,我正在编写一个远程/浏览器内日志记录工具(基本上是一个浏览器内控制台,这样我就可以远程调试移动设备等等),但我在打印/访问一些原始DOM元素和对象(当我将它们记录到控制台时,它们似乎是对象)时遇到了问题。在事件对象上调用bronsole(不要判断我)时,一些DOM对象没有被循环通过,好像for循环没有将其识别为对象一样。有问题的对象之一是HTMLpropertiescollection。我对这个项目没有特别的需求,但是我正在记录触摸事件,如果能够读取事件对象的所有属性就好了 (function

如果($(this).height()
HTMLPropertiesCollection
是父元素的集合,其子元素是特殊的HTML5
microdata
元素,这是一个相对较新的东西。因此我认为您正在测试此内容的页面没有
microdata
,因此
HTMLPropertiesCollection
将为空:我可以
console.log(HTMLPropertiesCollection)
我得到了类似于
getlength 0 getnames对象{length=0,item=item(),contains=contains()}@iterator@@iterator()item()namedItem()\uu proto\uuu
Werid的东西。我想我需要更多的上下文,我只得到了
HTMLPropertiesCollection()
当我记录它时,以及
当我
为(HTMLPropertiesCollection中的k){console.log(k);}
一件很奇怪的事情。你在使用什么浏览器?我使用的是FF 29。在Chrome 37中甚至都做不到这一点,当我试图用它做任何事情时,只是得到了旧的“ReferenceError:HTMLPropertiesCollection未定义”。
