(jQuery, mootools, dojo) Use a programming alias that suits you_jquery

For example, you can often see the following code in jQuery

Copy the code The code is as follows:

( function($){
//some code
})(jQuery)

This way you can use $ instead of jQuery;

In mootools you can Written like this, because in mootools $$ represents a set

Copy the code The code is as follows:

(function($){
//do sth.
})(document.id)

In Dojo you can write like this

Copy code The code is as follows:

(function(d,$){
})(dojo,dojo. query)

In this case, you can use $ instead of dojo.query in dojo; to achieve fast conversion from jQuery to dojo;
To imitate mootools, you can write like this

Copy code The code is as follows:

(function(d,$,$$){
/ /do sth;
})(dojo.dojo.ById,dojo.query)

This way you can use $ instead of dojo.ById and $$ instead of dojo.query;
