dialog获取焦点
弹出层是一个iframe
openWindow: function (options) {
var url = options.url;
url += url.indexOf("?") > 0 ? "&" : "?";
url += "ran=" + Math.random();
var isScroll = options.isScroll ? ‘yes‘ : ‘no‘;
rcpnDetail.mainWindow = $("<div></div>");
rcpnDetail.mainWindow.html(‘<iframe frameborder="0" width="100%" scrolling="‘ + isScroll + ‘" height="‘ + options.height + ‘" src="http://www.mamicode.com/‘ + url + ‘"></iframe>‘)
.dialog({
width: options.width,
title: options.title,
name: options.name,
isDraggable: true,
afterClose: options.afterClose

}
