两个listbox实现选项的添加删除和搜索_javascript技巧

两个listbox实现选项的添加，删除和搜索

贴一下主要的js代码，一些资源我就不传了。下面是效果图。

group.js

复制代码 代码如下:

function addMember()
{
//右侧选中的项添加到左侧
var add=$("#newAddMembersId").val();
var del=$("#deleteMembersId").val();
var ext=$("#existedMemberId").val();
var newAddId="";
//获取新加的userId
var addedUsers=$("#enterpriseMember input:checkbox[checked]");
for(var i=0;i{
var checkbox=$(addedUsers[i]);
var uid=checkbox.next().val();
if(add.indexOf(uid)>=0 || (ext.indexOf(uid)>=0 && del.indexOf(uid){
continue;
}
if(!(ext.indexOf(uid)>=0 && del.indexOf(uid)>=0))
{
if(add.indexOf(uid){
if(add.length==0)
add+=uid;
else
add+=","+uid;
}
}
//添加数据到左侧列表
checkbox.removeAttr("checked");
var userDiv=checkbox.parent().parent().parent();
$("#groupMember").append(userDiv.clone());
del=del.replace(uid+",","");
del=del.replace(uid,"");
$("#deleteMembersId").val(del);

}

$("#newAddMembersId").val(add);

}

function removeMember()
{
//左侧移除成员
var add=$("#newAddMembersId").val();
var del=$("#deleteMembersId").val();
var newRemoveId="";

var removedUsers=$("#groupMember input:checkbox[checked]");
for(var i=0;i{
var checkbox=$(removedUsers[i]);
var uid=checkbox.next().val();
if(del.indexOf(uid)>=0)
{
continue;
}
if(del.indexOf(uid){
if(del.length==0)
del+=uid;
else
del+=","+uid;
}
//左侧列表中移除数据
checkbox.removeAttr("checked");
var userDiv=checkbox.parent().parent().parent();
userDiv.remove();
//$("#enterpriseMember").append(userDiv);
add=add.replace(uid + ",", "");
add=add.replace(uid, "");
$("#newAddMembersId").val(add);

}

$("#deleteMembersId").val(del);
}
//搜索成员，按名字,按部门
function searchMember()
{

var searchTxt=$.trim($("#searchTxt").val());
var memberLIsts=$(".dmlist");
//移除上次的结果
var lastReusts=$(".tempResult");
for(var i=0;i{
$(lastReusts[i]).remove();
}
//为空搜索显示全部列表
if(searchTxt=="" || searchTxt=="搜索企业成员")
{
//show all hidded ml
for(var i=0;i{
$(memberLIsts[i]).css("display","");
}
return ;
}
//hide all memberlist,隐藏所有的列表
for(var i=0;i{
$(memberLIsts[i]).css("display","none");
}
//搜索-------------
var enterpriseMemberDiv=$("#enterpriseMember");
//search by name,add class:tempResult
var names=$(".sname");
for(var i=0;i{
var name=$(names[i]).text();
if(name.indexOf(searchTxt)>=0)
{
var result=$(names[i]).parent().parent().parent().clone();
result.addClass("tempResult");
result.css("display","");
enterpriseMemberDiv.append(result);
}
}

//search by departmentName
var departmentNames=$(".sdepartment");
for(var i=0;i{
var name=$(departmentNames[i]).text();
if(name.indexOf(searchTxt)>=0)
{
var result=$(departmentNames[i]).parent().parent().parent().clone();
result.addClass("tempResult");
result.css("display","");
enterpriseMemberDiv.append(result);
}
}
}

if(txt=="搜索企业成员")
$("#searchTxt").val("");

}
function setsearchTxt()
{

}
