I have a requirement in my application to show the technical skills (tags) in auto-complete format like Stack Overflow has.

Is there any example to get the tags from Stack Overflow using JavaScript + JSON?

    By "...show the skills...", do you mean display the tags? Are you referring to the tag text entry box on the "Ask Question" page? Sep 28, 2011 at 17:49

Based on the information you've provided in your comment - I will now provide an example of how you might accomplish what you're looking to do.

The tags can be retrieved from the API using the /tags route - a sample request for Stack Overflow looks something like this (notice the results are paginated - you will receive the first 30 tags according to the default sorting method):


Now for auto-completion, you will need to make use of one of the parameters to the /tags route: filter. The filter is a query string parameter that causes the /tags route to return only the tags that contain the provided string. For example, to get all tags that contain the string 'vb', you would issue the following request:


Notice that there are far fewer tags returned. Also notice that every single one of them contains the string 'vb' somewhere in the name. In order to create a tag autocompletion text box like the one on the sites themselves, you will need one more piece of information: the description for the tag.

Fortunately, this is easy to - it's provided in the Tag Wiki route. Here is an example that fetches the tag wiki for Perl:


In the response, you will find an entry 'wiki_excerpt' - this can be used for the tag description. To get the wiki for multiple tags, just separate them with a semicolon:


Now you have all of the pieces needed to re-implement the tag autocomplete you see on the Stack Exchange sites. When the user enters tags:

  1. Load all tags for the site filtered by the string the user has entered.
  2. Combine the returned list of tags with a semicolon and hit the /tags/.../wikis route.
  3. Now present the tags and descriptions to the user.

    thanks for your input George... I hope this API URL has to be called using JScript + JSON (any methods)... am expecting specifically that exmaple "Call to Stack API from Jquery to get the list of Tags"..

    @gunaSamba: Yes, all of the API URLs above can be accessed using JSONP. Sep 30, 2011 at 17:08
