jQuery1.9.1 Adjustment method for checkbox (prop) _jquery

In the jquery 1.8.x version, our check and uncheck actions for the checkbox are as follows:

Decide whether to select

Copy Code code as follows:

$ (' #checkbox '). Prop (' checked ')

To set the check and uncheck State:

Copy Code code as follows:

$ (' #checkbox '). attr (' checked ', true)
$ (' #checkbox '). attr (' checked ', false)

But this method is not the same in jquery1.9.1.

Ie10,chrome,ff, for the selected state, the first $ (' #checkbox '). attr (' checked ', true) enables
But when cleared by code, the next time you pass the code $ (' #checkbox '). attr (' checked ', true) to select
Although the code has checked= ' checked ', but the screen performance is not ticked.
There is no such problem under IE8,IE6.

After investigating the relevant information, it was found that attr (' checked ', true) is now replaced by prop (' checked ', true)
