I have two sites in which one has data and second has a user form. Daily basis we fill the form manually that form with reaching and watching that site. Is it possible to auto fill the form with the help bookmarklet programming?

I made the basic code to auto fill the form but how can i get the data from url.

javascript:(function()
{
    function f1(ele, val)
       {
         if(document.getElementById(ele) && ' ')
         {
          document.getElementById(ele).value = val;
         }
       }
     f1("first_name", "suraj");
     f1("last_name", "singh");
     f1("age", "20");
     f1("qualification", "12th");
        
})();

-further I want to get that data from other URL.
