$("-sharpbtn1").click(function () {
// $("-sharpck").attr("checked","true");
$("-sharpck").prop("checked",true);//true
});
$("-sharpbtn2").click(function () {
$("-sharpck").prop("checked",false);
});I would like to ask why the false and true here do not need quotation marks, and what is the reason for the usual use of quotation marks?
checked is already a Bool. why do you add quotation marks? don't quotation marks become string?
prop ("checked", "false") will also be treated as a check box, which is certainly not the effect you want, is it?

it is recommended to do the basics of DOM and JS first.
