jquery detect textbox exists


If my textarea exists when the page loads when I click to add another comment box it knows where to leave off.

for my example there is 2 already exists so when I click add another it should start at 3 not 2.

An easier way instead of a counter is to get the total number of text areas


var nextNumber = $('textarea').length + 1

The only thing I did was remove your counter variable before the click function and used it to set the counter on click.   You did the rest.
$("#addButton").click(function () {
    var counter = $('textarea').length +1
    if (counter > 3) {
        alert("Only 3 Comments are allowed");
        return false;
    $('<div/>', {
        'ID': 'CommentBoxDiv' + counter
    $('<label/>').html('Comment #' + counter + ' : '))
        .append($('<textarea  cols="40" rows="6">').attr({
        'id': 'Comments' + counter,
        'name': 'Comments' + counter,
        'style': 'margin-top:10px; margin-bottom:10px'

$("#removeButton").click(function () {
    if (counter == 1) {
        alert("No more Comment boxes to remove. One will remain.");
        return false;
    $("#CommentBoxDiv" + counter).remove();
