概述:
一般情况下都是通过ajax进行请求获取数据。boostrap+ajax
1、代码
//权限分配 $('#authority').click(function() { $("#jstree").jstree({ "core" : { "themes" : { "responsive": false }, // so that create works "check_callback" : true, 'data' : function (obj, callback) { var jsonstr="[]"; var jsonarray = eval('('+jsonstr+')'); $.ajax({ type: "GET", url:"/demo/authority/getAuthoritys", dataType:"json", async: false, success:function(result) { var arrays= result; for(var i=0 ; i<arrays.length; i++){ console.log(arrays[i]) var arr = { "id":arrays[i].id, "parent":arrays[i].parentId=="root"?"#":arrays[i].parentId, "text":arrays[i].name } jsonarray.push(arr); } } }); callback.call(this, jsonarray); } }, "types" : { "default" : { "icon" : "glyphicon glyphicon-flash" }, "file" : { "icon" : "glyphicon glyphicon-ok" } }, "state" : { "key" : "demo2" }, "plugins" : [ "dnd", "state", "types","checkbox","wholerow" ] }); $('#setAuthority').modal(); });
总结:
"responsive": false :表示主题是否适应手机类小尺寸屏幕,默认为false
"check_callback" : true:表示形成树是否可以重新组织,也是改变顺序,层次关系
callback.call(this, jsonarray):将数组放入树形
types:{}设置类型,图标
"state" : { "key" : "demo2" }:将选中的状态保存浏览器中
"plugins" : [ "dnd", "state", "types","checkbox","wholerow" ] 表示插件相关,详情参考点击打开链接
url路径换成你后台地址,返回时json数组
2、html标签
<!-- 权限分配模框--> <div class="modal fade" id="setAuthority"> <div class="modal-dialog"> <div class="modal-content message_align"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span> </button> <h4 class="modal-title">权限分配</h4> </div> <div class="modal-body"> <div id= "jstree"> </div> </div> <div class="modal-footer"> <input type="hidden" id="url" /> <button type="button" class="btn btn-default" data-dismiss="modal">取消</button> <a onclick="authorityConfirm()" class="btn btn-success" data-dismiss="modal">确定</a> </div> </div> <!-- /.modal-content --> </div> <!-- /.modal-dialog --> </div>
本文基于jstree使用AJAX请求获取数据形成树到此结束。立志趁早点,上路轻松点,目光放远点,苦累看淡点,努力多一点,奋斗勇一点,胜利把名点,祝你折桂冠,成功新起点,幸福多一点,笑容亮一点。小编再次感谢大家对我们的支持!
