Jquery checkbox checked, jquerycheckbox

1. question:

When first operate the checkbox with sentence like:

$ ("Input [type = checkbox]"). attr ("checked", true );

$ ("Input [type = checkbox]"). attr ("checkec", false );

It will succeed;

But the second time, it will failed. why ??

2. Cause:

If the attribute name of the tag is belong to the tag (the html defined), the prop (name, value) method works,

If the attribute name of the tag is m, then attr (name, value) method works.

3. Solution:

$ ("Input [type = checkbox]"). prop ("checked", true );

$ ("Input [type = checkbox]"). prop ("checked", false );

It works.
