Get Parameter

This is the most important function you will every need in your online endeavors. It is called getparm. You use it by calling it into a variable.

Example:

var recordnumber=getparm('parm'); [be sure your parameter match's what was passed]


Here is the function to get the parameter;

function getparm(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];
}
 
I found this function posted on the internet while working on a project. Similar solutions are posted all over the internet. Over the years, I have learned that if you need a solution, let your fingers do the walking. If you can't find what your looking for WALK AWAY AND THEN COME BACK, works every time.
