将编码的JSON加载到Dojo Grid中

问题描述

我正在PHP编程，
我想要一个数组我有（从mysql结果集中提取），将其转换为 JSON 然后在 dojox.grid.DataGrid 中使用它。

我从获得了一个想法：

我在数组中使用了以下内容（在名为的文件中，getJSON.php ）

  echo $ ajax ={identifier：'db_id'，'items'：json_encode ） }。 
  

然后我尝试这样做（在我的主页）：

  var store = new dojo.data.ItemFileWriteStore（{url：'getJSON.php'}）; 
  

其他所有内容与Dojo文档指定的完全一样。
网格显示，但不加载数据，而是写入对不起，发生错误

解决方案

我不使用ItemFileWriteStore！他们改变了很多Dojo 1.6，所以也许你看一些不是最新的东西。

尝试这段代码：

请尝试这个代码，首先回应一些简单的东西：

之后用你自己的JSON ...

I am programming in php,I want to take an array I have (which is extracted from mysql result set), convert it to JSON and then use it in dojox.grid.DataGrid.

I got an idea from this link:

I used the following on the array (in a file called getJSON.php)

echo $ajax = "{identifier: 'db_id', 'items':".json_encode($array)."}";

Then I try doing this (in my main page):

var store = new dojo.data.ItemFileWriteStore({ url: 'getJSON.php' });

Everything else is exactly as the Dojo documentation specifies.The grid shows up, but doesn't load the data and instead writes Sorry, an error occurred

Does anyone know the reason? Hopefully I gave you enough to go on.

解决方案

i don't use ItemFileWriteStore for that ! They changed a lot since Dojo 1.6 , so maybe you looked at something not up to date.

Try this code:

Please try this code by echoing something simple like this first:

And after that with your own JSON...
