当用户键入一些信息并回车时，就会调用下面的函数：
<input type="text" class="mytext"
id="mytext" onkeydown="captureReturn(event)">
// Capture the enter key on the input box and post message
function captureReturn( event )
{
if(event.which || event.keyCode)
{
if ((event.which == 13) || (event.keyCode == 13))
{
postText();
return false;
}
else {
return true;
}
}
}
function postText()
{
rnd++;
//Clear text box first
chatbox = getElement( "mytext" );
chat = chatbox.value;
chatbox.value = "";
