php+ajax 实现无限树列表
首先介绍我实现的是xhprof插件的日志转为无限树状图，先看效果图：
废话不多说，直接看代码：（辛辛苦苦敲了好久才搞定，逻辑比较多，新手多揣摩）
控制器：
1 <?php
2
3 namespace Admin\Controller;
4
7
8 class XhprofController extends AdminbaseController
9 {
10 function _initialize()
11 {
12 parent::_initialize();
13 }
14
15 //获取当前文件目录
16 public function index()
17 {
18 $file = scandir("./public");
19 $str = ".xhprof";
20 foreach ($file as $value) {
21 if (preg_replace("/($str)/", "", $value) != $value) {
22 $dir[] = $value;
23 }
24 }
25 // $count = count($dir);
26 // $page = $this->page($count, 20);
27 // $this -> assign( "Page", $page->show( 'Admin' ) );
28 $this->assign("dir", $dir);
29 $this->display();
30 }
31
32 //获取适当的结构
33 public function tree($file_name)
34 {
35 $file_path = "./public/xhprof/$file_name";
36 $file_name = str_replace('.', '', $file_name);
37 if (F($file_name)) {
38 $mainTree = F($file_name);
39 } else {
40 if (file_exists($file_path)) {
