easyui tree checkbox tree-hit
文笔不好,部分代码.只为笔记用!主要功能: 单击条目可选中对应的checkbox,单击非末节点展开/合并.
$(function() {$('body').layout();$('#tree').tree({url : '<%=doName%>?active=<%=active%>',checkbox:true,onClick:function(node){// 单击展开/合并var hit = $(node.target).children("span.tree-hit");if (hit.hasClass("tree-collapsed")) {hit.removeClass("tree-collapsed").addClass("tree-expanded");hit.next().addClass('tree-folder-open');var ul = $(node.target).next();ul.css('display','block');} else if (hit.hasClass("tree-expanded")) {hit.removeClass("tree-expanded").addClass("tree-collapsed");hit.next().removeClass('tree-folder-open');var ul = $(node.target).next();ul.css('display','none');} else {//单击选中checkboxvar checkbox = $(node.target).children("span.tree-checkbox");if(checkbox.hasClass("tree-checkbox0")) {checkbox.removeClass("tree-checkbox0").addClass("tree-checkbox1");} else {checkbox.removeClass("tree-checkbox1").addClass("tree-checkbox0");}}},//数据加载完成后对数据进行处理 onLoadSuccess:function(){ getChecked(); }});});function getChecked(){ //循环判断 var nodes = $('.tree-node');//树形div的class if(nodes.length>0) //过滤第一次加载时没有数据 { var u_id = "<%=oI%>".split(","); $('.tree-node').each(function(i){ var node_id = $(this).attr("node-id");//树形div中node-id，其中保存的是数据的ID if(u_id !="null"|| u_id != null || u_id !="" || u_id != "undefined"){ for(var i=0; i < u_id.length; i++) { if(node_id == u_id) { //$(this).addClass("tree-node-selected");//修改class为选定状态 //var node = $('#tree').tree('find',u_id); $(this).children(".tree-checkbox").addClass("tree-checkbox1"); } }}}); }}function process(){// 获取所有树节点var node = $('#tree').tree('getChecked');var nodes = "";for(var i=0;i<node.length;i++){// 树节点IDnodes += "'" + node.id + "'" + ",";} nodes = nodes.substring(0,nodes.length-1);var map = new Map(); map.put("active", "GETFJD"); map.put("Ug_id", nodes);AjaxSend("<%=sysPath%>/PT_FX_FAX.do", "json", map,delNode); }// 实现同步传输,服务器响应完毕后继续向下执行function AjaxSend(url, wdataType, data,successFunction) { wdataType = wdataType==""?"Intelligent Guess":wdataType; $.ajax({ url:url, type:'POST', dataType:wdataType, async:false,//----- data: data.Objects(), beforeSend:function(){ jBeforeSend() }, complete :function(){ jCompleted() }, error:function(event){ jError(event) }, success:function(event){ jSuccess(event,successFunction) } });}
