Question

How would I prevent sendMessageAppendData() from being prepended to the ‘newMessageSpace’ id if sendMessageAppendData() has already been executed in the current js session.

function sendMessageAppendData() {
return '<table id="newMessageBox1" cellpadding="0" cellspacing="0" style="border-radius: 3pt; width: 267px; border: 1px solid #CCCCCC">'+
           '<tr>'+
           '<td valign="top" class="font1" style="text-align: center; padding: 3pt">You are messaging <?php echo $row->firstname." ".$row->lastname ?></td>'+
           '</tr>'+
           '<tr>'+
           '<td valign="top" style="text-align: center; width: 253px; padding: 3pt">'+
           '<input autofocus placeholder="Type your message" id="responseMessage" spellcheck="false" autocomplete="off" class="textbox1" type="text" style="width: 185pt; height: 17px" /></td>'+
           '</tr>'+
           '</table>';
}

$('#clickSendAMessage').live('click', function() {
    $('#newMessageSpace').prepend(sendMessageAppendData());

});

With the help of using javascript global scopr variable

var Isexcuted=0;
function sendMessageAppendData() {
Isexcuted=1;
return '<table id="newMessageBox1" cellpadding="0" cellspacing="0" style="border-radius: 3pt; width: 267px; border: 1px solid #CCCCCC">'+
           '<tr>'+
           '<td valign="top" class="font1" style="text-align: center; padding: 3pt">You are messaging <?php echo $row->firstname." ".$row->lastname ?></td>'+
           '</tr>'+
           '<tr>'+
           '<td valign="top" style="text-align: center; width: 253px; padding: 3pt">'+
           '<input autofocus placeholder="Type your message" id="responseMessage" spellcheck="false" autocomplete="off" class="textbox1" type="text" style="width: 185pt; height: 17px" /></td>'+
           '</tr>'+
           '</table>';
}

$('#clickSendAMessage').live('click', function() {
    if(Isexcuted==0)
    $('#newMessageSpace').prepend(sendMessageAppendData());

});
