jquery checkbox Select, change status, changes, and click events

This common little knowledge point feels necessary to remember:

The three ways jquery judges checked:
. attr (' checked '); See Version 1.6+ return: "Checked" or "undefined"; 1.5-return: TRUE or False
. Prop (' checked '); 16+:true/false
. Is (': checked '); All versions: true/false//don't forget the colon!

Several ways to checked jquery assignment:
All jquery versions can be assigned this way:
$ ("#cb1"). attr ("Checked", "checked");
$ ("#cb1"). attr ("Checked", true);
jquery1.6+:p 4 Types of ROP assignment:
$ ("#cb1 ″). Prop (" checked ", true);//It's easy to say OH
$ ("#cb1 ″). Prop ({checked:true}); Map Key value pairs
$ ("#cb1 ″). Prop (" Checked ", function () {
Return true;//function returns TRUE or FALSE
});

Remember this: $ ("#cb1 ″). Prop (" Checked "," checked ");

* Full Marquee small case:

$ ('. All '). each (function(I,ELEMT) {    $ (the). Change(function() {             var ischecked = $ (this). Prop ("checked");            $ (this). Siblings (' input '). Prop ("Checked", ischecked);       } )
