我正在尝试使用Dojo DataGrid对象进行简单的“调整大小”行为。 “宽度”正如预期的那样正常工作。但是“高度”不起作用,并且网格仅显示初始渲染值。
这是HTML文件的超链接,并重现了问题。
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 ?");
}
}
}, "progButtonNode").startup();

DataGrid会在最初呈现时缓存其父内容框的大小,并且不会自动检测更改,因此请为网格指定大小:
grid.resize({ w: 400, h: 400 });
如果你想更通用一点:
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()
来删除缓存的值也会有效,但这很糟糕。
