how to achieve lazy loading of pictures for html code that has been written?
for example, many articles have been written, and many pictures have been applied to each article, which have been stored in the database. Now we need to revise them to achieve lazy loading of pictures
.methods you have tried
find out all the image,src replaced by the loading diagram, and add the attribute data-src to the initial src address. When the browser scrolls to the visual area, replace data-src to src.
.what result do you expect? What is the error message actually seen?
I expect whether there are better ideas or libraries that exist in the community to solve this problem, which will be very complicated if I try.
