问题描述

嗨


if（webbrowser1.documenttext.contains

{

webbrowser1.document.getelementbyid（aria-id-） 29371579884）.InvokeMember（点击）

messagebox.show

}





但是getelementbyclass不存在怎么能通过获得一个类来实现相同的结果



ps创建一个新线程，因为它是一个不同的问题，但我知道它仍然是相关的

Hi

{
webbrowser1.document.getelementbyid(aria-id-29371579884).InvokeMember("Click")
messagebox.show
}


However getelementbyclass does not exists how can i achieve the same result by by getting a class instead

p.s made a new thread because it is a different question but i know it is still related

推荐答案

不要尝试按类来做！如果你想使用一个唯一元素，只有属性 id 应该保证唯一性。确保你有id =aria-id-29371579884。使用：

Don''t try to do it by class! If you want to use one unique element, only the attribute id is supposed to guarantee uniqueness. Make sure you have id="aria-id-29371579884". Use:

someElement = document.getElementById("aria-id-29371579884"); // note casing and quotation marks!
// do something with the element

按类和许多其他选择器进行选择，请查看jQuery：http://api.jquery.com/category/selectors/ [ ^ ]。



请记住，除 id选择器之外的所有选择器都会为您提供元素集，不一定是一个。

For selection by class and many other selectors, check out jQuery: http://api.jquery.com/category/selectors/[^].

Remember that all selectors except the id selector gives you the set of element, not necessarily one.
