Echo a php function in a javascript -

i have following javascript

function showit(item,i,j,max){   var id;   actualitem=item;   for(var x=1;x<=i;x++){     id=item+"_"+x;     document.getelementbyid(id).src="<?= suburl(); ?>/b.gif";   }   for(var x=i+1;x<=max;x++){     id=item+"_"+x;     if(x<=j)       document.getelementbyid(id).src="<?= suburl(); ?>/y.gif";     else document.getelementbyid(id).src="<?= suburl(); ?>/w.gif";   } } 

i have tried <?= suburl(); ?> , <?php echo suburl(); ?>

function suburl(); looks this:

function suburl() {   $suburl = 'http://localhost/www.site.com/static';   echo $suburl; } 

and it's not working on echoing in javascript. appears pure html. it's appreciated thank you.

you try this:

function showit(item,i,j,max){   var id;   actualitem=item;   var url = suburl(); //this new   for(var x=1;x<=i;x++){     id=item+"_"+x;     document.getelementbyid(id).src=url+"/b.gif";   }   for(var x=i+1;x<=max;x++){     id=item+"_"+x;     if(x<=j)       document.getelementbyid(id).src=url+"/y.gif";     else document.getelementbyid(id).src=url+"/w.gif";   } }  function suburl() {   var suburl = 'http://localhost/www.site.com/static';   return suburl; }
