后台获取json格式数据。
直接上代码。 最后有一张官方ajax获取tree的说明。
var ajaxTreeSample = function() {$("#tree_4").jstree({"core" : {"themes" : {"responsive": false}, // so that create works"check_callback" : true,'data' : function (obj, callback) {var jsonstr="[]";var jsonarray = eval('('+jsonstr+')');$.ajax({type: "POST",url:"/bms/wechat/wemenu/show.do",dataType:"json",async: false,success:function(result) {var arrays= result.data;for(var i=0 ; i<arrays.length; i++){var arr = {"id":arrays[i].menuId,"parent":arrays[i].parentId=="root"?"#":arrays[i].parentId,"text":arrays[i].menuName}jsonarray.push(arr);}}});callback.call(this, jsonarray);}},"types" : {"default" : {"icon" : "fa fa-folder icon-state-warning icon-lg"},"file" : {"icon" : "fa fa-file icon-state-warning icon-lg"}},"state" : { "key" : "demo3" },"plugins" : [ "dnd", "state", "types" ]});}
