head區(qū)域主要是一段按下“批量刪除”之后要處理的事件，就是上面的

代碼如下：

復(fù)制代碼代碼如下:

function delIt() 
{ 
var cbxBool = 0; 
for(var i = 0;i < cbxArray.length;i++){ 
var obj = document.getElementById(cbxArray[i]); 
if(obj.checked == true){ 
cbxBool = 1; 
break; 
} 
} 

if(cbxBool == 1){ 
var result = confirm("操作不可以恢復(fù)，確定當(dāng)前操作嗎？"); 
if(result){ 
return true; 
} 
}else{ 
alert("您還沒有選中項(xiàng)"); 
return false; 
} 
return false; 

}
