使用Javascript获取字符串的一部分

Question

I have a string (from the pathname in the url) and I am trying to pull out part of it, but I'm having trouble.

This is what I have so far:

^(/svc_2/pub/(.*?).php)

The string is:

/svc_2/pub/stats/dashboard.php?ajax=1

How can I get a regex that returns /pub/stats/dashboard only?

Answer 1

For this, using a regex is too much, but here is:

var string = "/svc_2/pub/stats/dashboard.php?ajax=1";
console.log(string.replace(/.*(\/pub.*)\.php.*$/,"$1"));

But you can do it, without a regex, like this

console.log(string.substr(6,string.indexOf(".php")-6));

In both cases, the console.log will give you /pub/stats/dashboard

Answer 2

If it's always that format (I'm assuming the /svc_2/ is always there) this should do it.

var s = "/svc_2/pub/stats/dashboard.php?ajax=1";
var match = s.match(/\/svc_2(.+)\./)[1];

But not if anything comes before that.

Answer 3

This is not very flexible, but should work in this specific case.

var basedir = '/svc_2/', str = '/svc_2/pub/stats/dashboard.php?ajax=1';
str = str.substring(basedir.length, str.indexOf('.'));
alert(str);
