我在使dojo EnhancedGrid可编辑方面遇到问题。 目前,我可以双击网格单元格,我可以更改值,但是当我再次按Enter键或尝试离开单元格时(即将新值保存到网格中),我收到“在ItemFileWriteStore中断言失败”我的萤火虫中的错误。
以下是我的源代码:

}
]];
var mystore = new dojo.data.ItemFileWriteStore({
url: "movies.json"
});
// create a new grid:
var grid = new dojox.grid.EnhancedGrid(
{
query: {},
store: mystore,
structure: layoutabc
},
document.createElement("div")
);
dojo.byId("gridDiv").appendChild(grid.domNode);
grid.startup();
});
</script>
</head>
<body class="claro">
<div id="gridDiv" style="width: 800px; height: 400px;">
</div>
</body>
这是我的movies.json的内容(数据的内容很奇怪,我知道):
{
items:
[
{
title: "Africa",
year: "continent",
producer: "Katia Lund"
},
{
title: "Kenya",
year: "country",
producer: "Christine Jeffs"
},
{
title: "Mombasa",
year: "city",
producer: "Ridley Scott"
}
]
}

问题解决了。事实证明,我需要为EnhancedGrid对象定义“plugins”属性,即使它只是一个空对象。一旦定义它就可以正常工作。

我认为问题在于您的商店不包含任何标识符,因此当网格尝试写入商店时,它无法知道应该写入哪个条目。
我首先要编辑movies.json的响应,也许是这样的:
{
identifier:"id",
items:
[
{
id:1
title: "Africa",
year: "continent",
producer: "Katia Lund"
},
{
id:2
title: "Kenya",
year: "country",
producer: "Christine Jeffs"
},
{
id:3
title: "Mombasa",
year: "city",
producer: "Ridley Scott"
}
]
}
请注意,您不必在布局列表中包含id字段,无论如何都可以访问网格。此外,正如标识符所暗示的那样,它必须是商店中每个商品的唯一值,否则将无法初始化。
