Can I add a <br/> and links to a javascript alert?

Question

I have the following statement:

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?

How can I do this with my example?

When I added the \n, the alert doesn't show up.

Answer 1

No, alert() only allows plain text. So \n is a line break.

Answer 2

You cannot allow links but you can have newlines.

Just use "\n" for a newline instead of <br/>.

Answer 3

You can't use HTML, but you can add line breaks:

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.

Answer 4

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.

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)

Answer 5

You can't use markup in a javascript alert. However, you can achieve line breaks using "\n"

Answer 6

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...

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..

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.

Answer 7

Short answer: you can't. Javascript dialogs are basic.

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.

The alternative is to fake it in HTML, which a large number of Javascript libraries provide built-in functionality for.
