Question

我有一段javascript在JQuery 1.7下运行得很好，但在1.8下它不合作。基本上我有一个全局变量，用于限制人们在函数内的2条注释：

<script src="scripts/jquery-1.8.1.min.js"></script>
<script language="javascript" type="text/javascript">
var postNumber = 0;
function sendComment() {
  var formData = $('#commentForm').serialize();
  var url = "photo.php";
  if ($("#comment").val() == "") {
    $("#interactionResults").html('&nbsp; Please type something.').show().fadeOut(6000);
  } else {
    if (postNumber < 2) {
      $("#pmFormProcessGif").show();
      $.post(url, formData, function(data) {
        var returnString = data;
        if (returnString.match(/^Error:/)) {
          $("#interactionResults").html(data).show().fadeOut(6000);
        } else if (postNumber == 0) {
          $('#newCommentDisplay').html(returnString).show();
        } else if (postNumber == 1){
          $('#newCommentDisplay2').html(returnString).show();
        }
        document.commentForm.comment.value='';
        $('#pmFormProcessGif').hide();
        ++postNumber;
      }); // end post
    } else {
     $('#interactionResults').html("<p>To combat spam, we only allow 2 posts at a time.<br />Please refresh your browser and try again. Thank you.<p>").show();
    }//end if postNumber
  }
}
</script>

代码仍然有效，但由于某些奇怪的原因，它不再将postNumber增加到1。这是html部分：

<form action="javascript:sendComment();" method="post" name="commentForm" id="commentForm">
  <textarea name="comment" cols="35" rows="5" id="comment"></textarea><br />
  <input type="hidden" name="photo" id="photo" value="<?php echo $getID; ?>" />
  <input type="submit" name="button" id="button" value="Submit"/>
  <span id="pmFormProcessGif" style="display:none;"><img src="images/loading.gif" width="28" height="10" alt="Loading" /></span>
</form>
<div class="commentDisplayList">
  <div id="newCommentDisplay2"></div>
  <div id="newCommentDisplay"></div>
</div>

为什么这在JQuery 1.8中不再起作用（全局变量）
