我想从html中删除dom events属性列表?这该怎么做?像:
before = "<div onclick="abc" >abc</div>"
after = clean_it(before) // after => "<div>abc</div>"
DOM_EVENT_TO_BE_REMOVE = "onclick|ondblclick|onerror|onfocus|onkeydown" // i want to remove these events
// i want to do it like this
def clean_it(html)
doc = Hpricot(html)
doc.search(DOM_EVENT_TO_BE_REMOVE).remove_attribute(DOM_EVENT_TO_BE_REMOVE)
doc.to_s
end
感谢。

使用“remove_attr”,例如:
doc.search("[@onclick]").remove_attr("onclick")
因此,为您的文档执行以下操作:
DOM_EVENT_TO_BE_REMOVE = ["onclick", "ondblclick", "onerror", "onfocus", "onkeydown"]
DOM_EVENT_TO_BE_REMOVE.each do |de|
doc.search("[@#{de}]").remove_attr(de)
end
