Hi all,

i ve a function which is responsible for some validations, disabling and enabling of some text boxes and a group of radio buttons ....

now i want to generate the function name to be called from another function using a for loop and then appending the for loop index to the function in question ....

something like this .....

function unCheckRadio(num) 
    {
	  var cont = num;
	  var form = document.angular;
	  
          for (var i = 0; i < cont; i++) 
	  {
	       for(var j = 0; j < form['lim_set'+i].length; j++ )
	       {
                    form['lim_set'+i][j].checked = form['lim_set'+i][j].defaultChecked;
	       }
	      makeChoice_ang();
         }
	  
    }

here i want to append the index i to the makeChoice_ang() function ....

tried many ways .... but no go ...

i tried using this .... ();

but this is making it an string ....

Please help me out or atleast point me in the right direction ....

Thanks a million in advance !!

I hope this will help you:

<html>
    <script>
        function callAll() {
            for(var i = 0; i < 3; i++) {
                window['myFunction' + i](i);
            }
        }
        function myFunction0(i) {
            alert(i);
        }
        function myFunction1(i) {
            alert(i);
        }
        function myFunction2(i) {
            alert(i);
        }
    </script>
    <body onload='callAll()'>
    </body>
</html>

But this is not a good practise.

Hi,

or you might also want to try this simulated document.
In this demo i will verify all the checkboxes set to have defaulted checked values:

   for ( i = 0; i < num; i++ ) {
      chb = form[ String( "lim_set" + i ) ];
      chb.checked = chb.defaultChecked;
      if ( chb.defaultChecked ) {
      isChecked[ i ] = chb.id;
/*

   position of the i variable

      var makeChoice_ang = ( function( index ) {
         var div;
         (( div = document.getElementById( "output" )) ? div : div =  document.all.output );
         div.innerHTML = "";
         div.innerHTML += "<br><br>This are the following checkboxes the has ( checked by default ) on the page:<br><hr>";

         for ( checkedItem in index ) {
            document.angular[ index[ checkedItem ]].style.border = "2px solid #F00"; 

/* This will highlight the ( checked by default ) checkboxes in your page. */
            div.innerHTML += "<span style=\"color : #365d95; letter-spacing : 2px;\"><b>checkbox #" + (( checkedItem * 1 ) + 1 ) + "</b> — capturing i-index @:<br> position = <b>" + (( checkedItem * 1 ) + 1 ) + "</b></span><br><hr>";
         } delete checkedItem; 
      return;
      } )( isChecked );
      }
   } delete i; 
return false;
} );
