i have my post form code as below:

///////////////////////////////

<textarea class="bp-suggestions" name="whats-new" id="whats-new" cols="50" rows="10" placeholder="Share the moment?" onfocus="this.rows=80;" onkeypress="return LimitThis()" onkeyup="textAreaAdjust(this);return CountThis(ActivityLimit)" onmouseover="return CountThis(ActivityLimit)" wrap=physical maxLength="280"><?php if ( isset( $_GET['r'] ) ) : ?>@<?php echo esc_attr( $_GET['r'] ); ?> <?php endif; ?></textarea>
<p><span id="ActivityLimit">280</span></strong></p>

<script>
function textAreaAdjust(o) {
    o.style.height = "1px";
    o.style.height = (25+o.scrollHeight)+"px";
}

function LimitThis() {
	var myObject=event.srcElement;
	if (myObject.value.length==myObject.maxLength*1) return false;
}

function CountThis(visCnt) { 
	var myObject=event.srcElement;
	if (myObject.value.length>myObject.maxLength*1) myObject.value=myObject.value.substring(0,myObject.maxLength*1);
	if (visCnt) visCnt.innerText=myObject.maxLength-myObject.value.length;
	
}
</script>
