The difference between attr and prop methods in JQuery

Some browsers just write disabled,checked, and some should be written disabled = "Disabled", checked= "checked", such as attr ("checked") The Checked property of the checkbox can be obtained when the value is selected, the value is "checked", but the get value is undefined.

JQ provides a new method of "prop" to get these properties, which is to solve this problem, we used attr to get the checked property when we return "checked" and "", and now use the Prop method to get the property is unified return True and false.

So, when to use attr (), when to use Prop ()?

1. Add property name This property will take effect should use Prop ();

2. There are true,false two attributes using prop ();

3. The other uses attr ();
