The ondblclick event handler captures a double-click event from the user’s mouse button on the element to which the ondblclick attribute is applied. This will usually result in a call to a script method such as a JavaScript function. Note that the onclick event handler will fire before the ondblclick event handler.

Note that this event attribute cannot be applied to the following elements:

  • applet
  • base
  • basefont
  • bdo
  • br
  • font
  • frame
  • frameset
  • head
  • html
  • iframe
  • isindex
  • meta
  • param
  • script
  • style
  • title


Here, the ondblclick event handler calls a function called openFile:


It can also be used to run a script in situ:

ondblclick="alert('My, you are a quick clicker');"


This attribute has no fixed value. It’s up to the author to decide on the scripting that’s included here, be that a call to one or more defined functions, or a simple alert() statement.

However, the likely values will be similar to this:


You could also specify a value like this:


You may also use a value like this:

ondblclick="alert('Hello, double-clickers of the world. You only
➥needed to click once, you know.');window.close();"

Note that you can string several functions together, separating them with a semicolon, as shown in the second and third examples above.

Every browser listed supports this attribute. However, inline event handlers such as this should be avoided. In the same way that inline CSS styles are frowned upon but externally defined CSS styles are considered good practice, inline event handlers should be stripped out and replaced with events attached unobtrusively through the DOM.
