Extract keyword from Google search in Javascript

Question

I\'d like to extract from the url of a Google search the keyword of the search (e.g. for the keyword \"car\" : http://www.google.com/webhp?hl=en#sclient=psy&hl=en&si

Answer 1

Below sample code works for me for a single parameter and current URL but can be modified as per requirement.

function extract( name )
{
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  if( results == null )
    return "";
  else
    return results[1];
}

just use it as shown below,

var result= extract("your parameter name");
