In the past, for better browser compatibility, jQuery-1.7.2 version has been used; however, with the rapid development of major browsers and technologies, even the new bootstrap version needs to introduce jQuery-1.9 or above. version, which means that the commonly used jQuery-1.7.2 should bid farewell to the stage of history;

But some of our commonly used functions have also been deprecated; if you don’t pay attention, various errors will be reported; let’s take a look at these abandoned functions; of course, if you don’t know these abandoned functions introduced; then congratulations! There is no need to remember it, you just need to understand its replacement function; the purpose of this article is to remind you which functions have been deprecated and which functions should be used to replace them; as for the specific use of the replacement function, please ask Gu Gedu Niang.

If you want to switch events; you can use the custom function below;

var i=0;
