Encountered problems operating checkbox
Select all

Copy code The code is as follows:

$ ("input[type='checkbox']").each(function(){
this.checked=true
})
Invert
$("input[type='checkbox'] ").each(function(){
if(this.checked){
this.checked=false
}
else{
this.checked=true
}

Theoretically, it should be possible to use $(obj).attr("checked",true) to operate evil. However, it works fine under IE, but the anti-checking effect fails under firfox. $(obj).removeattr ("checked") doesn't work, I don't know what's going on.
Just use js to operate the dom attribute directly, no problem.
