I have the following statement:
我有以下声明:
btnApply.Attributes.Add("onclick", "alert('Must be a member to Use this Tool')");
Is there a way to add a new line. I tried, but it showed the in the text. In addition, can I add a link that would close the alert and take the user to another page?
有没有办法添加新行。我试过,但它在文中显示了。此外,我可以添加一个链接来关闭警报并将用户带到另一个页面吗?
How can I do this with my example?
我怎么能用我的例子呢?
When I added the \n, the alert doesn't show up.
当我添加\ n时,警报不会显示。

You can't use HTML, but you can add line breaks:
您不能使用HTML,但可以添加换行符:
alert('line1\nline2');
If a rich modal popup is really what you want though, you can use jQuery's dialog feature and put whatever you want in there.
如果你想要的是丰富的模态弹出窗口,你可以使用jQuery的对话框功能并在那里放置任何你想要的东西。

Use \\n (needs two slashes).
使用\\ n(需要两个斜杠)。
You'll notice that before doing this the alert will not post even a javascript error. \n will not work because the slash needs to be escaped.
您会注意到,在执行此操作之前,警报甚至不会发布javascript错误。 \ n将无法工作,因为需要转义斜杠。

You cannot allow links but you can have newlines.
您不能允许链接,但可以使用换行符。
Just use "\n" for a newline instead of <br/>.
只需使用“\ n”代替换行符。

Javascript has a specific AlertDialog that it opens when you you call alert('') and treats the entire body as text - far as I know there is no way of adding HTML to the displayed dialog.
当你调用alert('')并将整个主体视为文本时,Javascript有一个特定的AlertDialog,就像我知道没有办法在显示的对话框中添加HTML一样。
I'd recommend using a Javascript library that supports a customizable dialog box or modal box like this Modal Box to get your desired behavior (and it will look better)
我建议使用一个Javascript库,它支持一个可自定义的对话框或模态框,就像这个Modal Box一样,以获得你想要的行为(它看起来会更好)

You can't use markup in a javascript alert. However, you can achieve line breaks using "\n"
您无法在javascript警报中使用标记。但是,您可以使用“\ n”实现换行符

Alert is a fairly crude tool (and looks it too). Perhaps it's time to look at doing this in a more web friendly way...
警报是一个相当粗糙的工具(也看起来也是如此)。也许现在是时候以更友好的方式来看待这个......
Create a hidden message div on your page and instead of executing the alert, populate it with some message mark-up (including an anchor link if you wish) and reveal it to the user instead. You can add all kinds of nice visual tricks to this including fading in/out, centring, layering a semi-opaque background, etc, etc..
在您的页面上创建一个隐藏的消息div,而不是执行警报,用一些消息标记(如果您愿意,包括一个锚链接)填充它,并将其显示给用户。你可以添加各种漂亮的视觉技巧,包括淡入/淡出,居中,分层半透明背景等等。
edit: jQuery dialog (as mentioned by others) is a nice way to handle this, most libraries will have some widget or another to do similar.
编辑:jQuery对话框(正如其他人所提到的)是处理这个问题的好方法,大多数库都会有一些小部件或其他类似的东西。

Short answer: you can't. Javascript dialogs are basic.
简答:你不能。 Javascript对话框是基本的。
You can use VBScript's MsgBox method to create a custom dialog box but that'll only work on Internet Explorer with VBScript turned on. Not cross-platform; not recommended.
您可以使用VBScript的MsgBox方法创建自定义对话框,但这只能在启用了VBScript的Internet Explorer上运行。不是跨平台的;不建议。
The alternative is to fake it in HTML, which a large number of Javascript libraries provide built-in functionality for.
另一种方法是在HTML中伪造它,大量的Javascript库为其提供内置功能。

as Gumbo said, \n is working 100%. But don't forget to give spaces between text and the \n
正如Gumbo所说,\ n正在100%工作。但是不要忘记在文本和\ n之间留出空格

No, alert() only allows plain text. So \n is a line break.
不,alert()只允许纯文本。所以\ n是一个换行符。

Maybe you can try confirm() instead alert(). This solution is not a link, but a redirection from button.
也许你可以尝试confirm()而不是alert()。此解决方案不是链接,而是从按钮重定向。
If you wrap the confirm into other var and check for true/false, you can perform 2 actions.
如果将confirm包装到其他var并检查true / false,则可以执行2个操作。
var r=confirm("Do you wanna do"); if (r==true) { window.location.assign('register.html'); // this will be append to current url. For other, use http:// full url assignement. } else { window.location.assign(''); // cancel does nothing }
var r = confirm(“你想做”); if(r == true){window.location.assign('register.html'); //这将附加到当前网址。对于其他人,请使用http:// full url assignement。 } else {window.location.assign(''); //取消不做任何事情}
