<script type="text/javascript" src="http://www.google.com/jsapi"></script>

   google.load("language", "1");        
   function translate_keyword(){
    var text = document.getElementById("Laws_keyword").value;
   
       google.language.detect(text, function(result)     
         {     
             if (!result.error && result.language)     
                {    
               google.language.translate(text, result.language, "en", function(result)     
                      {    
                         var translated = document.getElementById("Laws_keywordEN");                
                          if (result.translation!="")     
                           {    
                              translated.value = result.translation;                
                           }              
                      });    
               }          
         });
