I'm sure this shouldn't be so hard!

I've been struggling with facebook's javascript: I need to redirect to a URL based on the value in a select drop down menu, something like:
我一直在为facebook 的 javascript苦苦挣扎：我需要根据选择下拉菜单中的值重定向到一个 URL，例如：
<form name="cityselect">
<select name="menu" onChange="location=document.cityselect.menu.options[document.cityselect.menu.selectedIndex].value;" value="GO">
<option value="http://www.leeds.html">Leeds</option>
<option value="http://www.manchester.html">Manchester</option>

Can anybody help me get this working? I've had good look though the facebook dev forum and docs but either don't understand what needed or can't find the answer!

Try {} this.options also your urls are mistyped. http://www.leeds.htmlshould be http://www.leeds.com, not sure if that is related but just wanted to point that out just in case.
尝试 {} this.options 您的网址也输入错误。http://www.leeds.html应该是http://www.leeds.com，不确定这是否相关，但只是想指出来以防万一。
<form name="cityselect">
<select name="menu" onChange="window.document.location.href=this.options[this.selectedIndex].value;" value="GO">
<option selected="selected">Select One</option>
<option value="http://www.leeds.com">Leeds</option>
<option value="http://www.manchester.com">Manchester</option>
</select>
</form>
Parent Frame:
父框架：
<form name="cityselect">
<select name="menu" onChange="top.location.href=this.options[this.selectedIndex].value;" value="GO">
<option selected="selected">Select One</option>
<option value="http://www.leeds.com">Leeds</option>
<option value="http://www.manchester.com">Manchester</option>
</select>
</form>

how to remember selection after redirect.
重定向后如何记住选择。
for example
例如
let us suppose there are many city name in drop down. when i select city name in drop down then relevant page should appear on website and selection of current city should remain on redirected page until selection not changed
让我们假设下拉列表中有很多城市名称。当我在下拉列表中选择城市名称时，相关页面应出现在网站上，当前城市的选择应保留在重定向页面上，直到选择未更改
all redirect on same domain with subdomain all sub domain layout same dropdown will be available on all pages of website.
与子域在同一域上的所有重定向所有子域布局相同的下拉列表将在网站的所有页面上可用。
