如何从Url客户端获取ID？

Question

If I have a URl like "/api/User/Details/2c021192-25cb-43e1-9bba-3bd5604a0a3d" what would be the best way to get the ID "2c02ds92-25cb-43e1-9bba-3bd5604a0a3d" out of the URL client side?

I need to be able to build a $.getJSON request with the ID and I'm looking for the cleanest way to do it using JavaScript, jQuery, etc. Thanks

$.getJSON('/api/User/2c021192-25cb-43e1-9bba-3bd5604a0a3d')...

Answer 1

Use regular expressions and extract the appropriate part (which seems to be UUID) from the URL.

The alternative is to just split the string by / and get last element.

EDIT : The example on how to retrieve UUID from the URI:

var url = '/api/User/2c021192-25cb-43e1-9bba-3bd5604a0a3d';

var pattern = /[\da-f]{8}\-[\da-f]{4}\-[\da-f]{4}\-[\da-f]{4}\-[\da-f]{12}/;
var match = url.match(pattern)[0];

url.match(pattern) returns array of matches, so assuming there is at least one, and only one match, you should pick it (using [0] , as in the example).

EDIT 2 : Shortened the pattern used for matching (see revision history for comparison).

Answer 2

If the id is always going to be the last section of the URI, you could do something like

var url_array = document.location.split('/');
var id = url_array[url_array.length - 1];

Answer 3

using split , convert the url to an array of parameters. Then last array item in your case would be your ID.

there are very sophisticated URL parsers out there for javascript, perhaps you should look around on google for one that suits your needs.

Answer 4

尝试这个

alert("/api/User/Details/2c021192-25cb-43e1-9bba-3bd5604a0a3d".split('/').slice(-1)[0]);

Answer 5

The simpliest:

var id = '/api/User/2c021192-25cb-43e1-9bba-3bd5604a0a3d'.split('/User/')[1];

Gives you 2c021192-25cb-43e1-9bba-3bd5604a0a3d ;
