The jquery selector is very similar to the CSS selector, and the CSS selector provides many functions, both of which are parsed using right-to-left parsing, because when the render tree is established, if the Meici match does not succeed, it needs to be returned and matched, and the inverse parsing uses the exclusion method. The gradual narrowing of the element candidate set optimizes the process of finding the parent element from the child element, which is effective for a large number of eleme
