EXTJS动态设置GridPanel高度

上代码。自己看。

var girdHeight = Ext.getCmp("gird").getHeight();

var gird3Height = Ext.getCmp("gird3").getHeight();

var gird2Height = girdHeight-gird3Height-10;

//alert(gird2Height);

gird2.setHeight(gird2Height);

//窗口重绘时改变grid2高度

window.onresize=function(){  

girdHeight = Ext.getCmp("gird").getHeight();

gird3Height = Ext.getCmp("gird3").getHeight();

gird2Height = girdHeight-gird3Height-10;

gird2.setHeight(gird2Height);

};
