Attribute-value pairs from URL.

 / Published in: JavaScript
 
Interface

  • function()
  • function (string globalvariablename)
  • function (string globalvariablename, string attributevaluepair)

Description

Construct an array of attribute-value pairs from the search part of the url or an user specified string.

The result is returned from an anonymous function so the global name space won't be corrupted. A user can also provide a string to be the name of a global variable to store the result table.

Bookmarklet

The bookmarklet is generated by Closure Compiler .
