How to get the last part of a string in JavaScript?
JavascriptJavascript Problem Overview
My url will look like this:
http://www.example.com/category/action
How can I get the word "action". This last part of the url (after the last forward slash "/") will be different each time. So whether its "action" or "adventure", etc. how can I always get the word after the last closing forward slash?
Javascript Solutions
Solution 1 - Javascript
One way:
var lastPart = url.split("/").pop();
Solution 2 - Javascript
Assuming there is no trailing slash, you could get it like this:
var url = "http://www.mysite.com/category/action";
var parts = url.split("/");
alert(parts[parts.length-1]);
However, if there can be a trailing slash, you could use the following:
var url = "http://www.mysite.com/category/action/";
var parts = url.split("/");
if (parts[parts.length-1].length==0){
alert(parts[parts.length-2]);
}else{
alert(parts[parts.length-1]);
}
Solution 3 - Javascript
str.substring(str.lastIndexOf("/") + 1)
Though if your URL could contain a query or fragment, you might want to do
var end = str.lastIndexOf("#");
if (end >= 0) { str = str.substring(0, end); }
end = str.lastIndexOf("?");
if (end >= 0) { str = str.substring(0, end); }
first to make sure you have a URL with the path at the end.
Solution 4 - Javascript
Or the regex way:
var lastPart = url.replace(/.*\//, ""); //tested in FF 3
OR
var lastPart = url.match(/[^/]*$/)[0]; //tested in FF 3
Solution 5 - Javascript
Check out the split method, it does what you want: http://www.w3schools.com/jsref/jsref_split.asp
Solution 6 - Javascript
Well, the first thing I can think of is using the split
function.
string.split(separator, limit)
Since everyone suggested the split function, a second way wood be this:
var c = "http://www.example.com/category/action";
var l = c.match(/\w+/g)
alert(l)
The regexp is just a stub to get the idea. Basically you get every words in the url.
l = http,www,example,com,category,action
get the last one.
