使用php为jstree生成备用JSON
我试图在PHP控制器中为jstree生成备用JSON代码 我正在创建看起来正确的数据,但是jstree没有显示它 我的javascript如下所示:使用php为jstree生成备用JSON,php,jquery,ajax,json,jstree,Php,Jquery,Ajax,Json,Jstree,我试图在PHP控制器中为jstree生成备用JSON代码 我正在创建看起来正确的数据,但是jstree没有显示它 我的javascript如下所示: $this->registerJs(" $(function() { $('#statustree').jstree({ 'core' : { 'data' : {

调用时微调器旋转,但微调器消失,并且“我的树”不显示
我怀疑我没有正确地生成备用JSON响应,但我尝试的任何东西都不起作用
谢谢
-John您正在生成的数据看起来很好(前提是您在开发工具中看到的对jsTree发出的AJAX调用的响应) 您可能需要检查所有的头文件是否都正常-它是否真的作为JSON提供?您还可以尝试添加字符集,以防万一:
header('Content-Type: application/json; charset=UTF-8');
我看到您已经在尝试强制jQuery将响应视为JSON,而不考虑标题,但是使用“dataType”
而不是“dataType”
如果这不起作用-请分享您在开发人员控制台的网络面板中看到的内容-jsTree发出的AJAX调用的标题和响应。JSON.stringify({'a':'foo'})==JSON格式的对象当您对数组进行JSON编码时,您可以执行类似于$tree[0]=new array()而不是$tree[0][0]=new student的操作
