前言
zTree 是一个依靠 jQuery 实现的多功能 “树插件”。优异的性能、灵活的配置、多种功能的组合是 zTree 最大优点。 支持静态 和 Ajax 异步加载节点数据. 在开发中我们常需要用到树状的展示.

异步zTree加载
前面的配置相同,在此不再阐述.主要是js不同.
异步JS
var setting = {
check: {
enable:
true
},
data : {
simpleData : {
enable :
true
}
}
};
function initTree(){
var payFreq = $(
"#payFreq").val();
var fyType = $(
'#fyType').val();
var setHzType = $(
'#setHzType').val();
$.ajax({
url :
"/demo/initTree",
data : {payFreq:payFreq,
fyType:fyType,
setHzType:setHzType
},
success:
function(object){
var nodes =
"";
$.each(object.data,
function(i,item) {
nodes+=
"{id:'"+item.id+
"', pId:'"+item.pid+
"', name:'"+item.name+
"', isParent:'"+item.isParent+
"'},";
});
var zNodes =
"["+nodes+
"]";
var json =
eval(
'(' + zNodes +
')');
zTreeInit(json);
}
});
}
function zTreeInit(json) {
$.fn.zTree.init($(
"#treeDemo"), setting, json);
var zTree = $.fn.zTree.getZTreeObj(
"treeDemo");
zTree.expandAll(
true);
setting.check.chkboxType = {
"Y" :
"ps",
"N" :
"ps" };
}
java代码
Controller层
@RequestMapping(
"initTree")
@ResponseBody
public DataMessage
initTree(String setHzType,String payFreq,String fyType){
params.put(
"setHzType", setHzType);
params.put(
"fyType", fyType);
params.put(
"fkmattr_xt", fkmattr_xt);
List<TreeInfo> treeInfos = feeTransferService.initTree(params);
return DataMessage.successData(treeInfos);
}
tree实体类
public class TreeInfo {
private String id;
private String pid;
private String name;
private String isParent;
}
