JavaScript多选框checkbox传递

工作中遇到的多选框传递问题，实际上需要将多选框用js拼成一个传，作为string传递过去，需要在表单中加一个隐藏的值，回写的时候，再用js解析此串，然后给多选框赋值，用到代码如下：

//将多选框拼串

function getCheckboxStrNew(objName){ 
    var objList  = document.getElementsByName(objName);
	var returnStr = '';
	for(var i = 0; i < objList.length; i++)
	{ 
        var obj = objList[i]; 
		if(obj.type=='checkbox' && obj.checked)
		{ 
            if(returnStr == '')
			{
                 returnStr = '\''+obj.value+'\'';
			}
			else
			{
				returnStr = returnStr+',\''+obj.value+'\'';
			}//end if/else
		}//if(obj.type=='checkbox' && obj.checked)
	}//end for

	return returnStr;
}


//返回来串设置多选框值

//复选框判断是否选中
function checkboxJudge(objName,valueListStr){ 
    var objList  = document.getElementsByName(objName);
	for(var i = 0; i < objList.length; i++)
	{ 
        var obj = objList[i]; 
		if(obj.type=='checkbox' && valueListStr.indexOf(obj.value) > -1)
		{  
            obj.checked = true;
		}
	}
} 
 

//jsp代码

    <td width="15%"  align="right" bgcolor="f5f5f5" rowspan="3">是否输出
