Separte a sting and put int variables

I have the following function:

<script language=JavaScript>
{
ctrl = window.location.search.substr(8).substring(5);
}
</script>

The "ctrl" value becomes "Equip&Descr=Descr"

I need to separate the string that´s in the "crl" into 2 more variables. I need that it reads "Equip" and put´s it in a variable and then reads "Descr" and put´s it in anther variable. How can I do this ???

Hi fabyola,

Here's another way. Say you have:

var ctrl = "Equip&Descr=Description";

You can do this:

var v1 = ctrl.split("=");

Now, v1[0]="Equip&Descr", and v1[1]="Description"

Then, you can do this:

var v2 = v1[0].split("&");

Of course, now v2[0]="Equip" and v2[1]="Descr" .

Put it all together and here it is:

var s1=ctrl.split("&")[0]; // <-- should be "Equip"
var s2=ctrl.split("&")[1].split("=")[0]; // <-- should be "Descr"
var s3=ctrl.split("=")[1]; // <-- should be "Description"

Peace and joy. mvan

Hehe, here's a nasty one:

<script>

var ctrl = "Equip&Descr=Description";

// Next line creates variable named Equip, and sets it = 'Description' !!
eval("var "+ctrl.split("&")[0]+"='"+ctrl.split("=")[1]+"'");
alert("Equip = "+Equip);

// Next line creates variable named Descr, and sets it = 'Description' !!
eval("var "+ctrl.split("=")[0].split("&")[1]+"='"+ctrl.split("=")[1]+"'");
alert("Descr = "+Descr);

</script>

Pro'ly not good programming practice. ;-)

Peace and joy. mvan

or you can try this function:

function getParameter ( queryString, parameterName ) {
      //Use like UniqueID = getParameter ( location.search , "uid" );

      // Add "=" to the parameter name (i.e. parameterName=value)
      var parameterName = parameterName + "=";
      if ( queryString.length > 0 ) {
            // Find the beginning of the string
            begin = queryString.indexOf ( parameterName );
            // If the parameter name is not found, skip it, otherwise return the value
            if ( begin != -1 ) {
                  // Add the length (integer) to the beginning
                  begin += parameterName.length;
                  // Multiple parameters are separated by the "&" sign
                  end = queryString.indexOf ( "&" , begin );
                  if ( end == -1 ) {
                        end = queryString.length;
                  }
                  // Return the string
                  return unescape ( queryString.substring ( begin, end ) );
            }
            // Return "null" if no parameter has been found
            return "null";
      }
}

use it like:

alert("Equip = "+getParameter(location.search, "Equip"));
alert("Descr = "+getParameter(location.search, "Descr"));

hope this helps too, cheers
