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();


}
