基本jquery的控制tabs打开的数量的代码

var tabcount = $(#tabs).tabs(tabs).length;修改addTab 方法为：function addTab(subtitle, url, icon) {
var tabcount = $(#tabs).tabs(tabs).length;
if (tabcount <= 5) {
if (!$(#tabs).tabs(exists, subtitle)) {
$(#tabs).tabs(add, {
title: subtitle,
content: createFrame(url),
closable: true,
icon: icon
});
} else {
$(#tabs).tabs(select, subtitle);
$(#mm-refresh).click();
}
} else {
alert(您打开的太多了，请关闭不用的窗口！);
return false;
}
