jQuery Treeview将无法在异步模式下工作 [英] jQuery treeview wont work in async mode

问题描述

ive从 http://jquery.bassistance.de/treeview/)，而我就遇到了问题，因为它不会产生任何可见的东西.

ive downloaded a treeview plugin for jquery (from http://jquery.bassistance.de/treeview/) and ive got a problem with it, because it doesnt generate anything visible.

我已经用php生成了一个json字符串:

Ive generated a json string with php:

[{"text": "RSS feed"}, 
 {"text": "Documents", children: [{"text": "test.txt"}]}, 
 {"text": "Todo lists"}]

jquery代码如下:

The jquery code looks like this:

$("#baskets_tree").treeview({collapsed:false,url: "http://localhost/json.php?q=baskets"});

当然还有该文件包含一个列表:

and of course the file contains a list:

<ul id="baskets_tree"></ul>

所有内容均已加载，请求了json代码，并且屏幕上没有任何变化. 那么这可能是什么问题呢?有什么想法吗?

Everything is loaded, the json code is requested, and nothing changes on the screen. So what could be the problem with this? Any ideas?

推荐答案

如果您使用的是jQuery的新版本(1.4+) http ://www.jsonlint.com/

If you're using a new version of jQuery (1.4+) it'll silently fail because your JSON is invalid, check it here: http://www.jsonlint.com/

问题在于children属性也需要双引号，例如:

The issue is that the children property needs double quotes as well, like this:

[{"text": "RSS feed"}, 
 {"text": "Documents", "children": [{"text": "test.txt"}]}, 
 {"text": "Todo lists"}]

我当然不能说您是否还有其他 other 问题，但这是一个确定的显示限位器，如果您使用的是jQuery 1.4+，则需要修复该问题，看看是否可以解决该问题或让您更进一步.

I can't say if you have any other issues of course, but that's a sure show stopper and one that needs fixing if you're on jQuery 1.4+, see if that resolve the issue or gets you further along.
