<! DOCTYPE html>
　　
The method $.prop in jquery is slightly different from the $.attr method. Prop is used in intrinsic HTML properties, while attr is often used in our custom properties.
So the difference is here:
<input id= "Chk1" type= "checkbox"/> Multi-box with checked attribute <input id= "chk2" type= "checkbox" checked= "true"/> Multi-box with checked property
The results of the Prop method are as follows:
$ ("#chk1"). Prop ("checked") = = false$ ("#chk2"). Prop ("checked") = = True
The results of the attr method are as follows:
$ ("#chk1"). attr ("checked") = = undefined$ ("#chk2"). attr ("checked") = = "true"
Also consider that the last page option is not a table list of 10 options for pagination
