篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了treegrid -表格树异步加载相关的知识,希望对你有一定的参考价值。

问题:

  机构维护时,前端框架用的是easyui,如果同步全加载会出现页面延迟严重,影响用户体验

 

解决:

  机构逐层加载,点击后加载

  逐层加载会出现一个问题:子节点只有点击后才能加载子集

  所以开始为叶子节点图标,点击后变成枝节点,不点就误以为到最后一层

  目前的解决办法是加载是提供状态属性,默认关闭,加载不到子集时展开状态为叶子节点图标

 

实现:

function initOrgMaintainDetail(versionId){
    var tree = $("#orgMaintainDetail").treegrid();
    var dataTree = ‘‘;
    $.ajax({
        url:‘./fileServiceType/getOrgTreeDetail‘,
        async:false,
        data: {
            Authorization: localStorage.token,
            versionId:versionId
        },
        success:function(data){
            dataTree = data;
        }
    });
  //开始加载机构树前两层 tree.treegrid({ data:dataTree, queryParams: { Authorization: localStorage.token, versionId:versionId }, idField:
‘orgTypeId‘, cascadeCheck:true, treeField:‘orgDesc‘, fitColumns:true, animate: true, columns:[[ {title:‘金融机构编码‘,field:‘orgTypeId‘,align:‘center‘,width:200}, {title:‘金融机构名称‘,field:‘orgDesc‘,width:300}, {title:‘是否启用‘,field:‘isActive‘,align:‘center‘,formatter:function(value){ return value == 1?‘启用‘:‘禁用‘; },width:100}, //{title:‘归属人行‘,field:‘reserved‘,align:‘center‘,width:200}, {title:‘归属地区‘,field:‘areaNo‘,align:‘center‘,width:150,formatter:function(value,rec){ var areaDscr =‘‘; $.ajax({ url:‘area/find‘, data:{ Authorization: localStorage.token,areaId:rec.areaNo}, type:‘POST‘, dataType:‘JSON‘, async:false, success:function(data){ areaDscr = data.AREA_DSCR; } }); return areaDscr; }}, {title:‘操作‘,field:‘operate‘,align:‘center‘,width:200, formatter:function(value,rec){ var add = "<a href=‘javascript:void(0);‘ onclick=\"openAddOrUptOrgPancyBox(‘" + 1 + "‘,‘"+ rec.orgTypeId + "‘,‘"+ 0 + "‘,‘"+ rec.org_lvl + "‘,‘"+ 1 + "‘,‘"+ 0 + "‘,‘"+ 0 + "‘);\"><font color=‘#1e90ff‘>新增</font></a>"; var editArea = "<a href=‘javascript:void(0);‘ onclick=\"onclickAreaPancyBox(‘" + rec.areaNo + "‘)\"><font color=‘#1e90ff‘>地区维护</font></a><br>"; var update = "<a href=‘javascript:void(0);‘ onclick=\"openAddOrUptOrgPancyBox(‘" + 0 + "‘,‘"+ rec.orgTypeId + "‘,‘"+ rec.orgDesc + "‘,‘"+ rec.org_lvl + "‘,‘"+ rec.isActive + "‘,‘"+ rec.ord + "‘,‘"+ rec.areaNo + "‘)\"><font color=‘#1e90ff‘>修改</font></a>"; var batchLoad = "<a href=‘javascript:void(0);‘ onclick=\"batchImportDBMS(‘" + rec.ORG_ID + "‘,‘"+ rec.LVL + "‘,‘"+ rec.ORG_ID + "‘)\"><font color=‘#1e90ff‘>批量导入BMS</font></a>"; if(rec.org_lvl == 1){ return add + "&nbsp;" + update + "&nbsp;"; }else{ return add + "&nbsp;" + update; } } } ]], onLoadSuccess: function (row, data) { tree.treegrid("collapseAll"); }, onBeforeExpand:function(row){ expandNode(row,tree,versionId); }, onDblClickRow: function (row) { tree.treegrid(‘toggle‘,row.orgTypeId); } }); } //追加子节点 function expandNode(row,tree,versionId){ $.ajax({ url: ‘./fileServiceType/getOrgNodeChilds‘, type: ‘POST‘, async:false, data: { Authorization: localStorage.token, org_lvl: row.org_lvl, p_Id: row.orgTypeId, versionId:versionId }, success: function (data) { if(data != ‘‘){ $.each(data, function(idx, obj) { var node = tree.treegrid(‘find‘,obj.orgTypeId); //该节点存在则不拼接 if(node==null){ tree.treegrid(‘append‘,{ parent: row.orgTypeId, data: [{ orgTypeId: obj.orgTypeId, orgDesc: obj.orgDesc, org_lvl: obj.org_lvl, areaNo: obj.areaNo, isActive:obj.isActive, ord:obj.ord, reserved:obj.reserved, state:obj.state }] }); } }); }else{ //没有数据则更改节点状态为叶子节点 tree.treegrid(‘update‘,{ id:row.orgTypeId, row:{
              //每层都默认有子集,直到查不到子集再展开 state:
‘open‘ } }); } } }); }

节点实体类:
