提问by Robin Carlo Catacutan
How can I parse this string on a javascript,
我怎样才能在 javascript 上解析这个字符串，
var string = "http://www.facebook.com/photo.php?fbid=322916384419110&set=a.265956512115091.68575.100001022542275&type=1";

try this :
var g=string.match(/set=[a-z]\.([^.]+)/);
g[1] will have the value

You could use split()to modify your code like this:
您可以split()像这样修改您的代码：
var newstring = string.match(/set=[^ ]+/)[0].split(".")[1];
For a more generic approach to parsing query strings see:
有关解析查询字符串的更通用方法，请参阅：
Parse query string in JavaScript
Using the example illustrated there, you would do the following:
使用此处所示的示例，您将执行以下操作：
var newstring = getQueryVariable("set").split(".")[1];
var newstring = getQueryVariable("set").split(".")[1];
