dojox.grid.DataGrid数据显示。
dojox.grid.DataGrid数据显示。
提问于 2012-03-05 20:33:35
我有这个JSP页面。当我运行它时，我没有得到任何错误。但是也不要使用数据网格来获取数据。

var grid = new dojox.grid.DataGrid({

});
//document.createElement('div'));
/*append the new grid to the div*/
//dojo.byId("gridDiv").appendChild(grid.domNode);
/*Call startup() to render the grid*/
grid.startup();
});
</script>

</body>
</html>我在myVar中获得了数据(用于JSP页面中的项目)，就像它在View source页面中显示的那样。但是仍然没有任何东西显示在屏幕上。我的HTML BODY标记中是否有任何错误。？请帮我弄一下这个。谢谢。

试着改变
var storedata={
identifier:"table1",至
var storedata={
identifier:"ID",请注意，identifier指定要用作数据中唯一标识符的项中的属性

你发布的html代码中有几个bug。
存储数据中的标识符不正确(正如Vijay指出的那样)。
myvar与myVar不同
我不相信Dojo1.4使用了HTML5数据属性，所以我将代码更新为使用1.7
我添加了网格样式表
