Question

我正在尝试使用多行消息显示FBJS对话框。

message += "Please enter the name of the Post.\n"
message += "Please enter content.\n"
message += "Content must have at least 10 characters.";

new Dialog().showMessage("Error", message);

但是那段代码在同一行显示了消息。

有人知道该怎么做吗？

感谢。埃内斯托·卡里翁

当你在对话框中显示除文本之外的其他内容时，你应该使用fb：js-string。

以下是一个例子：

<fb:js-string var="messageToShow">
  Here's some text.<br />
  and some more text...<br />
  <p>You can even have HTML or FBML tags in here!</p>
  <img src="http://absolute.path.to/the/image.jpg" />
  <form id="selectFriendForm">
    <label class="RedLabel">Select a friend:</label>
    <fb:friend-selector name="uid" idname="selected_friend" />
  </form>
</fb:js-string>

然后你有了显示对话框的功能：

<script type="text/javascript">
  function showDialog() {
    var dialog = new Dialog(Dialog.DIALOG_POP);
        dialog.showChoice('Select a friend',
        messageToShow, // fb:js-string var name
        button_confirm = 'Choose this friend',
        button_cancel = 'Cancel'
      );

    dialog.onconfirm = function() {
      var formData = document.getElementById('selectFriendForm').serialize();
      // ajax call to save my selected friend or whatever
    }
  }
</script>

FBJS对话框中的结束行“\ n”
