Recommended courses about lazyload.js

Have a question about lazyload.js lazy loading of pictures in the article? Modify the src attribute of the target img element to the orginal attribute to interrupt the loading of the image. The use of lazyloa needs to be like this. You need to add an orginal attribute to point to the original image. Then the pictures in my article need to be processed with regular expressions on the server side. How troublesome! ! ! Why can't lazyloa "collect" the image before the browser loads the image and prevent the browser from automatically loading the image? Doesn’t js have an event that the page is loaded (the html is loaded, but the resources are not loaded? It seems to be onreadystatechange or something, I forgot). I know there is such an event, doesn’t lazyloa know, and img is needed to cooperate with it? , what a beautiful thought, I already know how to change img like this, why do you still need lazyloa? Isn’t it just a matter of writing a scrolling event? Ask God for guidance!
