Can JS exchange onclick events of 2 DOMs?

Question

Instead of my own website, I made a browser. Some operations need to be hooked. Not very familiar with JS. Is it possible to exchange the click events of two elements? Baidu binds when all the function names are known. If it is unknown, how to get the click event function name of the element?

仅有的幸福 · Answer

Find the element, exchange event function, the function name does not exist

If jq does not need to be exchanged, directly trigger the click method of another element
