used code here, onkeypress = "return taLimit(250)", onkeyup = "return taCount(spcl,250)"


<script language="javascript">

   function taLimit(maxLength) {
       var taObj = event.srcElement;
       if (taObj.value.length === maxLength * 1) return false;
   }
   function taCount(visCnt, maxLength) {
       var taObj = event.srcElement;
       if (taObj.value.length > maxLength * 1) taObj.value = taObj.value.substring(0, maxLength * 1);
       if (visCnt) visCnt.innerText = maxLength - taObj.value.length;
   }

</script>

Isisombululo esikhethiwe

Try passing a reference to the textarea element to the function using this:

<textarea onkeypress="return taLimit(250, this)" onkeyup="return taCount(spcl, 250, this)"></textarea>

<script> function taLimit(maxLength, taObj) {   if (taObj.value.length === maxLength * 1) return false; } function taCount(visCnt, maxLength, taObj) {   if (taObj.value.length > maxLength * 1) taObj.value = taObj.value.substring(0, maxLength * 1);   if (visCnt) visCnt.innerText = maxLength - taObj.value.length; } </script>

The this keyword is a little tricky. I'm suggesting the approach listed under the heading Combination toward the end of this article: https://www.quirksmode.org/js/this.html

Does the console show any script errors?

You can set up demo pages on https://jsfiddle.net/ or https://codepen.io/ for interactive use.

I have already used "event.srcElement" but that is not supporting by mozilla is there any other solution?
