jquery removing checked doesn"t work, whether through attr or prop, it can only be set through dom. What"s going on?
let arr = $("input[name="courseGeneralType"]");
if(arr.length>0){
for(let i=0;i<arr.length;iPP){
// $(arr[i]).removeAttr("checked")
// $(arr[i]).removeProp("checked")
arr[i].checked=false;
}
}
