Today, I wrote a function to select all and cancel all:

Selection: $(" : "checkbox). Attr (" checked", "checked");

Uncheck all: $(":checkbox"). RemoveAttr ("checked");

Get checked: $(":checked[checked='checked']")

It's ok to click all, it's ok to click all, it's ok to click none, it's not ok to click any more

Selection: $(" : "checkbox). Prop (" checked", true)

Uncheck all: $(":checkbox").prop("checked",false)

Gets selected: $(":checkbox:checked")

The menu:
