ajax 笔记对CheckBoxList的简单操作

这个是在窗体一加载的时候就生成一个 checkBoxList .
function OnLoad_AllUser()
...{
    var res = Admin_usersRight.allRightValue();   //返回表中对应的角色说明出来
    var roleCommentId;
    var rightRole;
    var comment;
    var info = "";  
    
    var allComment = res.value.split("~");
    roleCommentId = allComment[0].split(",");
    rightRole = allComment[1].split(",");
    comment = allComment[2].split(",");
    for(var i = 0 ; i < roleCommentId.length - 1; i++)
    ...{
        info += '<tr><td><input id="CheckBoxList1_'+ rightRole[i] + '" type="checkbox" onclick="onclick_Value(' + rightRole[i] + ');"  name="CheckBoxList1$' + rightRole[i] +'" /><label for="CheckBoxList1_' + rightRole[i] +'">' + comment[i] + '</label></td></tr>'
    }
    document.getElementById("allRight").innerHTML = '<table id="Table1" border="0">' + info + '<tr><td><input type="button" id="btnRightSet" onclick="rightSet(1)" value="确定" /> </td></tr></table>';
}

下面这代码是对当选择某个checkBox时进行的操作

function onclick_Value( m )         //m是要设定的权限值
...{
    if(document.getElementById("CheckBoxList1_" + m).checked)
    ...{
        countNo += m + '~';            //当被选中时,就把他的m值记录下来
    }
    else                                        //又去掉时先前选中的m值
    ...{
        if(countNo.length>0)
        ...{
            var no = countNo.split("~");           //对 countNo 进行分析
            var max = no.length - 1;                 //取得最大值
            for(var i = 0; i < max ; i++)
            ...{
                 //如果用户去掉对钩时,那么这个地方就是把前先那个 m 值给掉,然后把后面的
                 //往前移. 如  countNo = "1,2,3,4,5,6,7,8,"       m = 4 ,现在就得把countNo 里的4去掉
                if(no[i] == m) 
                ...{
                    for(var j = i ; j < max ; j ++)
                    ...{
                        no[j] = no[j+1]
                    }
                }
            }
            countNo = "";
           // 下面这里重新给 countNo 赋值,些时 countNo = "1,2,3,5,6,7,8,";
            for(var i = 0 ; i < max -1 ; i++)
            ...{
                countNo += no[i] + '~';
            }
        }
        else
        ...{
        }
    }
}

 下面就是对刚才的操作开始执行了

function rightSet(status)  //这个是
...{
    var username = document.getElementById("txtUsername").value;
    var aa = Admin_usersRight.setUserRight(countNo,username,status,_doPostRightSetCallBack); 
    ShowUserRight();
}
