Sorry, where is the Javascript error?

probably this line:

javascript:alert('登入者名称 - ''NEW'' 错误。');(function() {var fn = function() {$get("ctl08_HiddenField").value = '';Sys.Application.remove_init(fn);};Sys.Application.add_init(fn);})();

Select allOpen in new window

How do you get such error message? I can see no problem, within the project (in Visual studio).

try check that in your web browser's Inspect feature.

i'm using FF, for your info.

Sorry, how to correct this

Uncaught SyntaxError: missing ) after argument list

in the following

function showMsg0() {
    $.message({
        title: '信息',
        content: 'new或NEW是保护字，不可以选为名字简称！',
        buttons: {
            OK: {
                text: 'OK',
                btnClass: 'btn-green',
                keys: ['enter'],
                action: function () {
                    //$.alert('You clicked OK!');
                }
            }
        }
    });
    return false;
};

Uncaught SyntaxError: missing ) after argument list

i found this error at code below instead:

javascript:alert('登入者名称 - ''NEW'' 错误。');(function() {var fn = function() {$get("ctl08_HiddenField").value = '';Sys.Application.remove_init(fn);};Sys.Application.add_init(fn);})();

can you probably remark it for testing purposes if you unable to solve it?

Sorry, is there any problem to this?

function showMsg0() {
    $.message({
        title: '信息',
        content: 'new或NEW是保护字，不可以选为名字简称！',
        buttons: {
            OK: {
                text: 'OK',
                btnClass: 'btn-green',
                keys: ['enter'],
                action: function () {
                    //$.alert('You clicked OK!');
                }
            }
        }
    });
    return false;

as tested earlier, i get this error:

are you forgot to include the message notification library into your page?

re-tested the website and it seems that you have not fixed it yet

are you forgot to include the message notification library into your page?

What library should be added?

>>What library should be added?

I believe this library was being used to generate the pop-up message.

what scripts are you included in order to do that? are you forgot to include it?

I already had such codes

    <link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" />
    <script type="text/javascript" src="https://code.jquery.com/jquery-1.12.4.js"></script>

to the page.

Now, there is originally, no mentioned problem to the page. Problem only arises, after I've entered 'new' to 1st field, on the page.

If I clicked that error, it was pointing to such part below

JavaScript1.js:281 Uncaught TypeError: $.message is not a function
    at showMsg0 (JavaScript1.js:281)
    at Default.aspx?userid=new&readonly=n:352

Select allOpen in new window

If I click error in above, it does point to this

<script type="text/javascript">
//<![CDATA[
(function() {var fn = function() {$get("ctl08_HiddenField").value = '';Sys.Application.remove_init(fn);};Sys.Application.add_init(fn);})();showMsg0()//]]>
</script>

greetings HuaMinChen, , , not sure I can help? ? , , but I have looked at the page code, and the comments here,  I will first say something about this error -

      javascript:alert('登入者名称 - ''NEW'' 错误。');(function() {var fn = function() {$get("ctl08_HiddenField").value = '';Sys.Application.remove_init(fn);};Sys.Application.add_init(fn);})();

Select allOpen in new window

In this you have too many single quotes on the word - NEW - as
        ''NEW''

it should be just single quotes as -
        'NEW'
not two quotes

- - - - - - - - - - - - - - -

Now in the -
     function showMsg0() {

you try and use an incorrect method as the message -
          $.message({

you can change this incorrect .message, , so you use a Jquery UI    .dialog    method to show a pop-up message, , however I searched and searched and I could not find any use or call in your javascript to the function
     showMsg0( )

and your code looks like it is just a TEST FUNCTION not ever used, you may should just delete from your code the entire   showMsg0( )   function? ?

Many thanks Slick.

Is it a problem to call JS event in Code behind like the following

                Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "showMsg0()", true);
				...
function showMsg0() {
    $.message({
        title: '信息',
        content: 'new或NEW是保护字，不可以选为名字简称！',
        buttons: {
            OK: {
                text: 'OK',
                btnClass: 'btn-green',
                keys: ['enter'],
                action: function () {
                    //$.alert('You clicked OK!');
                }
            }
        }
    });
    return false;
};

Where do you still see ''NEW'', on the page?

How to identify the problem to run this event?

function showMsg0() {
    $.message({
        title: '信息',
        content: 'new或NEW是保护字，不可以选为名字简称！',
        buttons: {
            OK: {
                text: 'OK',
                btnClass: 'btn-green',
                keys: ['enter'],
                action: function () {
                    //$.alert('You clicked OK!');
                }
            }
        }
    });
    return false;
};

The original issue is due to problem (on Web page) to run this event.

Thanks a lot.
Using these

function showMsg0() {
    $.dialog({
        title: '信息',
        content: 'new或NEW是保护字，不可以选为名字简称！',
        buttons: {
            OK: {
                text: 'OK',
                btnClass: 'btn-green',
                keys: ['enter'],
                action: function () {
                    //$.alert('You clicked OK!');
                }
            }
        }
    });
    return false;
};
