//全选/全不选
 $("#CheckAll").bind("click",function(){
  $("input[name='Check[]']").prop("checked",this.checked);
  //显示删除按钮
  /*if(this.checked == true){
    $("input[name='Delete'").css("display",'block');
  }else{
    $("input[name='Delete'").css("display",'none');
  }*/
 });

//批量删除
$("#Delete").click(function(){
 if(confirm('确定要删除所选吗"input[name='Check[]']:checked");
   if(checks.length == 0){ alert('未选中任何项！');return false;}
   //将获取的值存入数组
   var checkData = new Array();
   checks.each(function(){
    checkData.push($(this).val());
   });
   $.get("<{spUrl c=order a=delete}>",{Check:checkData.toString()},function(result){ if(result = true){ window.location.reload();}});
   }
 }
});

//获取被选中checkbox值
var checked = function(){
 var checks = $("input[name='Check[]']:checked");
 if(checks.length == 0){ alert('未选中任何项！');return false;}
 var checkData = new Array();
 checks.each(function(){
   checkData.push($(this).val());
 });
 return checkData;
};
//全选/全不选
$("#CheckAll").bind("click",function(){
  $("input[name='Check[]']").prop("checked",this.checked);
  //显示删除按钮
  /*if(this.checked == true){
   $("input[name='Delete'").css("display",'block');
  }else{
   $("input[name='Delete'").css("display",'none');
  }*/

//批量删除
$("#Delete").click(function(){
 if(val = checked()){
   if(confirm('确定要删除所选吗"<{spUrl c=order a=delete}>",{Check:val.toString()},function(result){ if(result = true){ window.location.reload();}});
