Today, I read the jquery handbook, a little bit more about the prop () function, a bad memory, and a record.

Prop (): Gets the value of the first element in a matching element set

Determine whether the first of the checkbox is selected:

$ (": CheckBox"). Prop ("checked");  Returns False if the first checkbox is checked to return true.

Disable and select all the check boxes on the page:

$ ("input[type= ' checkbox ']"). Prop ("disabled"true ); $ ("input[type= ' checkbox ']"). Prop ("checked"  true);

All check boxes on the Reverse selection page:

$ ("input[type= ' checkbox ']"). Prop ("checked", function ( I, Val) {   //i: Index  val:true/false (checked to True, otherwise false  )return !  Val;});
