javascript find node without id

由 笑着哭i 提交于 2019-12-24 01:27:12

I don't know if this is possible, but I'm trying to find the object via other means which will hopefully allow me to modify the id. The element I'm looking for is a button on a toolbar, but it's not an HTML button. It's a <div> that has CSS styles and Javascript events
