JavaScript String substr() Method

More examples below. The substr() method extracts a part of a string. The substr() method begins at a specified position, and returns a specified number of characters. The substr() method does not change the original string. To extract characters from the end of the string, use a negative start position. The substr() method is removed (deprecated) in the latest JavaScript standard.

JavaScript Substring Method | Refine

December 31, 2024 - While doing so, we elaborate on a few patterns of extraction from a parent string: namely, that of extracting a tail after first n characters, another of producing a substring composed of first n characters and that of extracting last n characters. In the later half of the post, we discuss some of the nuances associated with startIndex and endIndex values. In the end, we point out how JavaScript String.prototype.substring() compares to String.prototype.slice() as well as the deprecated method String.prototype.substr().

How to get substring after last specific character in JavaScript? - Stack Overflow

You can use String.slice with String.lastIndexOf:

var str = 'test/category/1';
str.slice(0, str.lastIndexOf('/') + 1);
// => "test/category/"
str.slice(str.lastIndexOf('/') + 1);
// => 1

The actual code will depend on whether you need the full prefix or the last slash. For the last slash only, see Pedro's answer. For the full prefix (and a variable PREFIX):

var PREFIX = "test/category/";
str.substr(str.lastIndexOf(PREFIX) + PREFIX.length);

How can I cut a substring from a string to the end using Javascript? - Stack Overflow

You can use indexOf and substr to get the sub-string you want:

//using a string variable set to the URL you want to pull info from
//this could be set to `window.location.href` instead to get the current URL
var strIn  = 'http://localhost/40ATV/dashboard.php?page_id=projeto_lista&lista_tipo=equipe',

    //get the index of the start of the part of the URL we want to keep
    index  = strIn.indexOf('/dashboard.php'),

    //then get everything after the found index
    strOut = strIn.substr(index);

The strOut variable now holds everything after /dashboard.php (including that string).

Here is a demo: http://jsfiddle.net/DupwQ/

UPDATE:

The strOut variable in the example above includes the prefixed forward slash and it was requested that the output should not.

Replacing strOut = strIn.substr(index) with strOut = strIn.substr(index + 1) fixes the output for this specific use case by starting the substring one character farther ahead in the string.

Something else you could do is search for the string after a specific search term (non-inclusive):

var strIn = 'http://localhost/40ATV/dashboard.php?page_id=projeto_lista&lista_tipo=equipe';
var searchTerm = '/dashboard.php?';
var searchIndex = strIn.indexOf(searchTerm);
var strOut = strIn.substr(searchIndex + searchTerm.length); //this is where the magic happens :)

strOut now holds everything after /dashboard.php? (non-inclusive).

This may be new, but the substring method returns everything from a specified index to the end of the string.

console.log(string.substring(5));

How to Use the Substring Method in Javascript (Code Examples)

October 28, 2021 - Beginning from 0 (as all indexes in JavaScript do), we count 5 characters from left to right of name. Substring selects the characters between the specified index arguments. The end index value is not included in the returned string from substring. Therefore, “dog”.substring(0,1) will return only ‘d’.
