若依项目人员选择器实现
下面主要记录一下在若依项目中，实现人员选择器功能。
使用了bootstrap Multiselect组件，其官网为：http://www.jiaoben123.com/uploadfiles/demo/d19cb85fac5b4c74bb4e387852f7d23b/#documentation
下载该组件的地址为：https://codeload.github.com/crlcu/multiselect/zip/master
1、下载好之后放在相应的js、css文件夹下，在include.html中分别引入该两个文件：
<link th:href="@{/css/multiselect-master/style.css}" rel="stylesheet"/>
<script th:src="@{/js/plugins/multiselect-master/multiselect.min.js}"></script>
2、在system/user/下新建tree.html，具体如下
<!DOCTYPE html>
<html lang="zh" xmlns:th="http://www.thymeleaf.org" >
<meta charset="utf-8">
<head th:include="include :: header"></head>
<link th:href="@{/ajax/libs/jquery-ztree/3.5/css/metro/zTreeStyle.css}" rel="stylesheet"/>
<style>
body{height:auto;font-family: "Microsoft YaHei";}
button{font-family: "SimSun","Helvetica Neue",Helvetica,Arial;}
</style>
<body class="hold-transition box box-main">
<input id="selectedUserIds" name="selectedUserIds" type="hidden" th:value="${selectedUserIds}"/>
<input id="selectedUserNames" name="selectedUserNames" type="hidden" th:value="${selectedUserNames}"/>
<input id="multiSelectFlag" name="multiSelectFlag" type="hidden" th:value="${multiSelectFlag}"/>
<div class="row">
<div class="col-xs-10">
<div class="wrapper">
<div class="treeShowHideButton" onclick="$.tree.toggleSearch();">
<label id="btnShow" title="显示搜索" style="display:none;">︾</label>
<label id="btnHide" title="隐藏搜索">︽</label>
</div>
</div>
<div class="treeSearchInput" id="search">
<label>姓名：</label><input type="text" class="empty" id="userName" name="userName" maxlength="50"/>
<button class="btn" id="btn" onclick="loadUserList()"> 搜索 </button>
</div>
</div>
</div>
<div class="row">
<div class="col-xs-4">
<div class="treeExpandCollapse">
<a href="#" onclick="$.tree.expand()">展开</a> /
<a href="#" onclick="$.tree.collapse()">折叠</a>
</div>
<div id="tree" class="ztree treeselect"></div>
</div>
<div class="col-xs-3" style="padding-top: 10px;">
<h4>待选人员</h4>
<select name="from" id="multiselect" class="js-multiselect form-control" size="15" multiple="multiple">
</select>
</div>
<div class="col-xs-1" style="padding-top: 40px;">
<button type="button" id="multiselect_rightAll" class="btn btn-block"><i class="glyphicon glyphicon-forward"></i></button>
<button type="button" id="multiselect_rightSelected" class="btn btn-block"><i class="glyphicon glyphicon-chevron-right"></i></button>
<button type="button" id="multiselect_leftSelected" class="btn btn-block"><i class="glyphicon glyphicon-chevron-left"></i></button>
<button type="button" id="multiselect_leftAll" class="btn btn-block"><i class="glyphicon glyphicon-backward"></i></button>
</div>
<div class="col-xs-3" style="padding-top: 10px;">
<h4>已选人员</h4>
<select name="to" id="multiselect_to" class="form-control" size="15" multiple="multiple"></select>
</div>
</div>
<div th:include="include::footer"></div>
<script th:src="@{/ajax/libs/jquery-ztree/3.5/js/jquery.ztree.all-3.5.js}"></script>
<script th:inline="javascript">
$(function() {
var url = ctx + "system/dept/treeData";
var options = {
url: url,
expandLevel: 2,
onClick : zOnClick
};
$.tree.init(options);
$('input[name="userName"]').on('input propertychange', function() {
loadUserList();
});
//获取多选标记
var multiSelectFlag = $("#multiSelectFlag").val();
//如果是非多选，进行如下处理，变成单选
if(!multiSelectFlag || multiSelectFlag != 'true'){
$("#multiselect_rightSelected").click(function(){
var checkValue=$("#multiselect").val();
if(checkValue != ''){
$("#multiselect_to option").each(function(){ //遍历所有option
var val = $(this).val(); //获取option值
var text = $(this).text(); //获取option文本内容
if(val!= ''){
$("#multiselect").append("<option value='" + val + "'>" + text + "</option>");
}
});
$("#multiselect_to").find("option").remove();
}
});
$("#multiselect_rightAll").hide();
$("#multiselect_leftAll").hide();
}
//1、初始化左右员工选择器
$('#multiselect').multiselect({
includeSelectAllOptions:true
});
//2、加载已被选择的人员
var selectedUserIds = $("#selectedUserIds").val();
var selectedUserNames = $("#selectedUserNames").val();
if(selectedUserIds != ''){
var idsArray = selectedUserIds.split(",");
var namesArray = selectedUserNames.split(",");
for(var i=0; i<idsArray.length; i++){
$("#multiselect_to").append("<option value='" + idsArray[i] + "'>" + namesArray[i] + "</option>");
}
}
//3、加载所有人员列表
loadUserList();
});
//点击部门树事件
function zOnClick(event, treeId, treeNode) {
var treeId = treeNode.id;
var treeName = treeNode.name;
loadUserList(treeId);
}
//加载人员方法
function loadUserList(deptId){
//清空当前待选择人员框列表
$("#multiselect").find("option").remove();
var userName = $("#userName").val();
var selectedUserIds = "";
//获取当前已选人员ids,用于过滤
$("#multiselect_to option").each(function(){ //遍历所有option
var val = $(this).val(); //获取option值
if(val!= ''){
selectedUserIds = selectedUserIds + val + ",";
}
});
//加载待选人员数据
$.ajax({
type: "get",
url: ctx +"system/user/listForTree",
traditional: true,
dataType : "json",
data:{
deptId : deptId,
userName : userName
},
success:function(result){
for (var i = 0; i < result.userList.length; i++) {//加载未拥有的角色 这里根据后台传递的对象循环添加
//与当前所选人员进行对比，待选人员中过滤掉已选的人员
if(selectedUserIds != ''){
var idsArray = selectedUserIds.split(",");
var flag = true;
for(var k=0; k<idsArray.length; k++){
if( idsArray[k] == result.userList[i].userId){
flag = false;
}
}
if(flag){
$("#multiselect").append("<option value='" + result.userList[i].userId + "'>" + result.userList[i].userName + "</option>");
}
}else{
$("#multiselect").append("<option value='" + result.userList[i].userId + "'>" + result.userList[i].userName + "</option>");
}
}
}
});
}
</script>
</body>
</html>
3、在需要人员选择的页面，进行该页面的调用，比如在新增部门的页面，选择部门负责人时：
<input type="hidden" name="leaderId" id="leaderId"> <div class="form-group"> <label class="col-sm-3 control-label">负责人：</label> <div class="col-sm-8"> <input class="form-control" type="text" name="leaderName" onclick="selectUserTree()" id="leaderName"> </div> </div>
//人员树形选择器 function selectUserTree() { var options = { title: '人员选择', width: "750", url: ctx + "system/user/selectUserTree?selectedUserIds=" + $("#leaderId").val() + "&selectedUserNames=" + $("#leaderName").val() + "&multiSelectFlag=false", callBack: doSelect }; $.modal.openOptions(options); } function doSelect(index, layero){ var body = layer.getChildFrame('body', index); var userIds = ""; var userNames = ""; body.find("#multiselect_to option").each(function(){ //遍历所有option var val = $(this).val(); //获取option值 var txt = $(this).text(); //获取option的文本内容 if(val!= '' && txt!=''){ userIds = userIds + val + ","; userNames = userNames + txt + ","; } }); userIds = userIds.substring(0,userIds.length-1); userNames = userNames.substring(0,userNames.length-1); $("#leaderId").val(userIds); $("#leaderName").val(userNames); layer.close(index); }
4、增加后台获取人员接口
/** * 选择人员树 */ @GetMapping("/selectUserTree") public String selectUserTree(String selectedUserIds,String selectedUserNames,Boolean multiSelectFlag,ModelMap mmap) { mmap.put("dept", deptService.selectDeptById((long)100)); mmap.put("selectedUserIds", selectedUserIds); mmap.put("selectedUserNames", selectedUserNames); mmap.put("multiSelectFlag", multiSelectFlag); return prefix + "/tree"; }
@GetMapping("/listForTree")
@ResponseBody
public String listForTree(SysUser user)
{
List<SysUser> list = userService.selectUserList(user);
JSONObject jsonObject = new JSONObject();
jsonObject.put("success", true);
jsonObject.put("userList", list);
return jsonObject.toString();
}
5、最后页面效果：
