Question

如果有人能够解释为什么我的Dialog'对话错误'没有解雇，我将不胜感激。在firebug中，响应正确显示并且没有错误。但由于某种原因，对话框没有响应它。非常感谢。

看起来你想要创建的div总是被添加到DOM中。我愿意：

$("html").append("<div id='dialog-success' />"); var $dialogSuccess = $("#dialog-success"); $dialogSuccess.html(' Your New Intake of ' + messageOutputs + ' was successfully submitted. Thank you.');

然后继续使用您的代码。
