How can I decode a URL with jQuery?

How 开发者_StackOverflow中文版can I decode a URL using jQuery? My url is

http%3A%2F%2Fdtzhqpwfdzscm.cloudfront.net%2F4ca06373624db.jpg

Try the decodeURIComponent function:

var decodedUri = decodeURIComponent('http%3A%2F%2Fdtzhqpwfdzscm.cloudfront.net%2F4ca06373624db.jpg');
alert(decodedUri);

Use decodeURIComponent(), for example:

decodeURIComponent("http%3A%2F%2Fdtzhqpwfdzscm.cloudfront.net%2F4ca06373624db.jpg")

It's not jQuery specific, this is a base JavaScript function.

You can simply call the standard javascript functions for encoding and decoding respectively.

encodeURIComponent
decodeURIComponent

Enjoy!

If you URL should also contain blanks encoded as '+', the following call will help (taken from https://stackoverflow.com/a/4458580/430742):

decodeURIComponent((str+'').replace(/\+/g, '%20'))

decodeURIComponent('http%3A%2F%2Fdtzhqpwfdzscm.cloudfront.net%2F4ca06373624db.jpg')
