previousElementSibling 而不是 previousSibling

Notes
Gecko-based browsers insert text nodes into a document to represent whitespace in the source markup. Therefore a node obtained, for example, using Node.firstChild or Node.previousSibling may refer to a whitespace text node rather than the actual element the author intended to get.

See Whitespace in the DOM and W3C DOM 3 FAQ: Why are some Text nodes empty? for more information.

对于不支持 previousElementSibling 的浏览器。循环获取 previousSibling ，直到其 nodeType 为 1
