   function sethdnfiletype(filetype)
   {
       $("#hdnfiletype").val(filetype);
   }
</script>

HTML

You can send values to a function using onclick, just pass them in as you would call a function usually.

function clickHandler(amount) {
  alert('Clicked with ' + amount);
}

<button type="button" onclick="clickHandler(123);">Click me</button>

You can use bind. Bind allows you to set some default parameters and the this context. So you could do this: sethdnfiletype.bind(this, 1); which would pass in the value 1 to your function as the first parameter and the event as the second parameter.
