Default Javascript question on reset and onfocus

1. How to reset textbox + textarea?
2. How to make the "function getKeyValue_h(chr)" work without the submit button? (on pasting in textarea it should automatically give the calculated result in the textbox.)

JavaScript:
Code:
<!-- 
//&&& 1st of 2 instances of getKeyValue(). changed name of Fx, '_h' for hebrew? 
function getKeyValue_h(chr) { 
  chr=chr.charAt(); 
  if(chr=="A") return 1; 
  if(chr=="B") return 2; 
  if(chr=="G") return 3; 
  if(chr=="D") return 4; 
  if(chr=="H") return 5; 
  if(chr=="V") return 6; 
  if(chr=="X") return 8; 
  if(chr=="+") return 9; 
  if(chr=="Y") return 10; 
  if(chr=="k" || chr=="K") return 20; 
  if(chr=="L") return 30; 
  if(chr=="m" || chr=="M") return 40; 
  if(chr=="n" || chr=="N") return 50; 
  if(chr=="$") return 60; 
  if(chr=="O") return 70; 
  if(chr=="p" || chr=="P") return 80; 
  if(chr=="c" || chr=="C") return 90; 
  if(chr=="q") return 100; 
  if(chr=="R") return 200; 
  if(chr=="S") return 300; 
  if(chr=="T") return 400; 
  return 0; 
} 


function computeValue(str) { 
  var ans=0; 
  for(var i=0; i<str.length; i++) { 
    ans+=getKeyValue(str.charAt(i)); 
  } 
  return ans; 
}
//-->
Within <body> (does it have to be in a form too?):
Code:
<br>
<textarea name="hInput" id="hInput" rows="9" cols="64"
 class="onLoad" onmouseover="this.className='onMouseOver'"
 onmouseout="this.className='onMouseOut'">
</textarea><br>
 
<input type="button" value="calculate value" onclick="javascript:computeValue(document.all.hInput.value, 'h');"> 

<input type="reset" value="Clear" name="B2">

<input type="text" name="hOutput" id="hOutput" readonly="true">

Default

You can use onchange event of the textarea/textbox to call function getKeyValue_h(chr)
