The jquery attr() method may cause problems when obtaining the checked tag, so the prop() method is used.

Hml's checkbox does not add a name, only p nesting is used.

If there is a better method, please give it!!

//全选$('#allChecked').change(function(){
     $('#box').children(':checkbox').prop('checked',$(this).is(':checked')?true:false);
});

Copy after login

//反选$('#invertChecked').change(function(){  
        if($(this).is(':checked')){
     $('#box').children(':checkbox').each(function(){
       $(this).prop('checked',$(this).is(':checked')?false:true);
     });
  }
});

//一键控制全选、反选、全不选
$('#orChecked').change(function(){
  if($(this).is(':checked')){
     var box = $('#box').children(':checkbox');
     if(box.length==box.filter(':not(:checked)').length){    // 复选框长度和没选中的个数一样 -> 全选 , .not(':checked').length 也可以。
     $('#box').children(':checkbox').prop('checked',true);
  }else{     // 如果有选中个数，-> 反选 
     $('#box').children(':checkbox').each(function(){     
        $(this).prop('checked',$(this).is(':checked')?false:true);
     });
  }else{
      $('#box').children(':checkbox').prop('checked',false);    // 如控制键取消选中，剩余的checkbox也取消选中
  }
    
});
