Every time when i pressed the enter key then it should alert some thing

Question

If i write some thing in input field and then i pressed enter then it should alert the specific value.Here is the code. please help me

<html>
<input type="text" class="searchfld" id='input' onchange="gotothatpost(this.value)"onkeyup="ajxsrch(this.value,getAscii())">
</html>
<script>
function ajxsrch(str,asci)
{
  if(asci==13)
   {
    alert("You pressed enter");
   }
  else
   {
    do something;
   }
}
</script>

@derstrom8 Agreed. The code, as shown, will never get called. `getAscii()` will be undefined and throw an exception, so `ajxsrch` will never get called. — Brian Genisio, May 04 '14 at 01:04

I am assuming you want us to define the getAscii() function for you. Using code partially modified from this answer, the following example should work.

<html>
<input type="text" class="searchfld" id='input'  onkeyup='ajxsrch(this.value, getAscii(event))'>
<script>
function getAscii(e) {
    if (window.event){ // IE                    
       return e.keyCode;
    }else {
         // Netscape/Firefox/Opera                  
        return e.which;
    }
}
function ajxsrch(str,asci)
{
  if(asci==13)
   {
    alert("You pressed enter");
   }
}
</script>
</html>

I was typing up my own getAscii function but you beat me to it! +1 – DerStrom8 May 04 '14 at 01:09
@derstrom8, I just modified the one I found on another answer. :) – merlin2011 May 04 '14 at 01:27
