为什么对话框不显示？

Question

The alert() works when the Send button is clicked but the dialog never shows. 单击“发送”按钮时，alert（）起作用，但对话框从不显示。 I have been going crazy trying to figure out why this is. 我一直在疯狂试图找出原因。 What am I doing wrong? 我究竟做错了什么？ Please see code below: 请参见下面的代码：

Hi I changed a little bit the code, I hope this works for you 嗨，我更改了一些代码，希望对您有用

function msg(){
$("#dialog_text").text('Login Successful');
$("#dialog_login").dialog({
    show: { effect: "blind", duration: 800 } 

  })
};

And you have other error 还有其他错误

 <div class="form-group">
                    <input type="submit" name="submit" value="Send" id="submit" class="btn btn-primary">
                </div

close the div with ">" 用“>”关闭div

 <div class="form-group">
                    <input type="submit" name="submit" value="Send" id="submit" class="btn btn-primary">
                </div>

Answer 2

OK, after many hours of looking at this I found the problem; 好吧，经过数小时的研究，我发现了问题； I had added '#' to the id: 我已经在ID中添加了“＃”：

<div id="#dialog_login" title="Login Status">

I corrected this: 我更正了这一点：

 <div id="dialog_login" title="Login Status">

Next I added this line to dg.js: 接下来，我将此行添加到dg.js：

$('#dialog_login').dialog({autoOpen: false});

So dg.js looks like this now: 所以dg.js现在看起来像这样：

function msg(){
$('#dialog_login').dialog({autoOpen: false});
$("#dialog_login").text('Login Successful');
$("#dialog_login").dialog('open');
alert('Login Successful');  
}

function loadMsg(){
    $("#dg").load("form.html");

I want to thank everyone who tried to help! 我要感谢所有尝试提供帮助的人！
