LazyTree 懒加载树形当父节点存在节点名称（ID）为message的节点时，子节点无法加载
测试代码

<ul id="table_tree" class="mini-tree" showTreeIcon="true" leafIcon="mini-tree-folder" showTreeIcon="true" textField="name" onbeforeload="onBeforeTreeLoad" onbeforeexpand="onBeforeExpand" idField="name" parentField="pid" resultAsTree="false"></ul>
<script type="text/javascript">
mini.parse();
function onBeforeExpand(e) {
var tree = e.sender;
var nowNode = e.node;
var root = tree.getRootNode();
tree.cascadeChild(root, function (node) {
if (tree.isExpandedNode(node)) {
if (node != nowNode && !tree.isAncestor(node, nowNode)) {
tree.collapseNode(node, true);
}
}
});
}
function onBeforeTreeLoad(e) {
var tree = e.sender; //树控件
var node = e.node; //当前节点
var params = e.params; //参数对象
}
mini.get('table_tree').load("/tree.php");
</script>

复制代码

PHP代码:

<?php
$name = empty($_REQUEST['name']) ? '' : trim($_REQUEST['name']);
if(empty($name))
{
echo '[{"id":1,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"admin"},{"id":2,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"admin_group"},{"id":3,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"loginlog"},{"id":4,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"message"},{"id":5,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"module"},{"id":6,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"session"},{"id":7,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"weather"}]';
}
else
{
echo "[{\"id\":1,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"id\"},{\"id\":2,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"tuid\"},{\"id\":3,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"tfullname\"},{\"id\":4,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"uid\"},{\"id\":5,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"ufullname\"},{\"id\":6,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"message\"},{\"id\":7,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"date\"},{\"id\":8,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"status\"},{\"id\":9,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"tdel\"},{\"id\":10,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"$name\",\"folder\":0,\"name\":\"udel\"}]";
}
?>

父级json

[{"id":1,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"admin"},{"id":2,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"admin_group"},{"id":3,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"loginlog"},{"id":4,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"message"},{"id":5,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"module"},{"id":6,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"session"},{"id":7,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"weather"}]

复制代码

message 节点json

[{"id":1,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"id"},{"id":2,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"tuid"},{"id":3,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"tfullname"},{"id":4,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"uid"},{"id":5,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"ufullname"},{"id":6,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"message"},{"id":7,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"date"},{"id":8,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"status"},{"id":9,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"tdel"},{"id":10,"isLeaf":true,"type":"txt","pid":"message","folder":0,"name":"udel"}]

只有父级为message的节点不能展开，如果我把父级的message改成messagex就可以问题。
是不是父节点不能命名为message?

是你else里的$name拼接错了吧
你试试把"$name\" 替换成".$name.\"试试呢

斜杠是PHP的转义而已。跟这个没关系。
PHP是正常输入我例子中的json文件的

那肯定是你返回的json字符串里面有问题了，json不正确
如果用.$name.去拼接一个字符串的话，我试了，是可以正常显示的

但我仅仅是父类是message的时候不能可以加载下级树，别的名称的父类都可以加载下级树
我看了返回的json没有问题

我打包个上来吧你测试下。

就是名字为message的节点打不开，别的都正常
下载最新的2.1.8版本也不行

你上面给的数据我在本地已经试过了，我换成是.$name.这种方式是可以正常显示的，说明你原来的echo的json字符串不正确啊。

但为什么别的节点能打开呢。。？你下载我的压缩包，在能运行PHP的环境运行下就明白了。
我的确试了不行
按你说的改了也是不行的。

<?php
$name = empty($_REQUEST['name']) ? '' : trim($_REQUEST['name']);
if(empty($name))
{
echo '[{"id":1,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"admin"},{"id":2,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"admin_group"},{"id":3,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"loginlog"},{"id":4,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"message"},{"id":5,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"module"},{"id":6,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"session"},{"id":7,"isLeaf":false,"type":null,"pid":-1,"folder":1,"name":"weather"}]';
}
else
{
echo "[{\"id\":1,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"id\"},{\"id\":2,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"tuid\"},{\"id\":3,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"tfullname\"},{\"id\":4,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"uid\"},{\"id\":5,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"ufullname\"},{\"id\":6,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"message\"},{\"id\":7,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"date\"},{\"id\":8,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"status\"},{\"id\":9,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"tdel\"},{\"id\":10,\"isLeaf\":true,\"type\":\"txt\",\"pid\":\"".$name."\",\"folder\":0,\"name\":\"udel\"}]";

恩，我这边也看下
另外，建议你用简单点的数据测试问题。1-2个节点就够了，没问题了再增加节点，不然过多的数据不好查看问题，尤其是字符串里面的问题
