JavaScript 在方法后面添加逻辑

common.js:

/*div跟随窗口大小动态变化*/
window.onresize= function(){
    $('.easyui-panel').panel("resize","auto");
    $('#itemData').datagrid("resize","auto");           
}   

其他.js

//保留菜单框架common.js的resize函数
var oldResizeFunction = window.onresize;
window.onresize = function(){
    console.log("div width"+$('#itemDiv').width() );
    oldResizeFunction();
}
