我正在尝试使用 Dojo DataGrid 对象进行简单的“调整大小”行为。 “宽度”按预期工作正常。但是“高度”不起作用，并且网格仅显示初始渲染值。
这是重现问题的 HTML 文件的超链接。
这是源代码:

if (grid){
grid.resize();
//grid.update();
dom.byId("result1").innerHTML = ("h: "+dom.byId("parentDiv").style.height+"/ w:"+dom.byId("parentDiv").style.width);
alert("Was grid resized ?");
}

最佳答案
DataGrid 在最初渲染时会缓存其父内容框的大小，并且不会自动检测更改，因此请为网格指定一个大小:
grid.resize({ w: 400, h: 400 });
如果你想更笼统一点:
var parentDiv = dom.byId('parentDiv');
grid.resize({ w: parentDiv.clientWidth, h: parentDiv.clientHeight });
通过将grid._parentContentBoxHeight设置为null然后调用grid.resize()来删除缓存的值也可以，但这很漂亮黑客。
关于javascript - Dojo DataGrid 高度调整大小不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31819910/
