jquery check and uncheck actions on checkbox

Recent projects found that jquery's full and non-select operations for the checkbox are only valid for the first time and will not take effect after the jquery repository is not known, and eventually a solution is found:

Put the original following two sentences:

$ (' input '). attr (' checked ', ' checked ');

$ (' input '). attr (' checked ', false);

Change to the following:

$ (' input '). Prop (' checked ', ' checked ');

$ (this). Removeattr ("checked");

The great gods are welcome to criticize and correct them.
