How to get Text BOLD in Alert or Confirm box?

Solution 1:

You can't do it. But you can use custom Alert and Confirm boxes.

You can read about some User Interface libraries here:

Most common libraries are:

  • http://jqueryui.com/
  • http://mootools.net/
  • http://www.prototype-ui.com/
  • http://script.aculo.us/
  • http://developer.yahoo.com/yui/

Solution 2:

The alert() dialog is not rendered in HTML, and thus the HTML you have embedded is meaningless.

You'd need to use a custom modal to achieve that.
