Javascript character count

Question

Example here: http://jsfiddle.net/67XDq/1/

I have the following HTML:

    17.
    

        

Answer 1

There are two issues in the fiddle

• no form element
• script mode was onload, which means that window object didnt have textCounter function

see updated fiddle http://jsfiddle.net/67XDq/7/, markup:

   17.
   
    Questions? Maximum of 500 characters - 
     characters left
    

    
   

and code

function textCounter(field, cnt, maxlimit) {         
  var cntfield = document.getElementById(cnt)   
  if (field.value.length > maxlimit) // if too long...trim it!
    field.value = field.value.substring(0, maxlimit);
    // otherwise, update 'characters left' counter
  else
    cntfield.value = maxlimit - field.value.length;
}
