I have this simpe Javascript script that show a popup box when a link is clicked:

    <script>
        function myExample() {
            alert("BaZing!  It works!");
        }
    </script>

I want to know if it is possible to format the text inside the alert() function.

In particular I want to know if (and how) is it possible to put some formatted HTML text as alert() input parameter.

Some one can help me?

• As long as it's a string, you can put anything you'd like in there? HTML and styles doesn't work on OS/browser specific windows, obviously! – adeneo Commented Oct 5, 2013 at 16:34
• You can't, use a custom modal. – alex Commented Oct 5, 2013 at 16:34

No, alert() accepts one string argument and will display it as is.

If you need to display a formatted text in a modal, use a library (e.g. Alertify.js).

alert() can't format a HTML format string, but if you just want separate a string to several lines, you can put '\n' in your string,like

alert("first line \n second line \n third line");
