Using asfunction in TextArea

Using asfunction in an UIComponent like TextArea

The asfunction protocol allows you to call Flash commands from hyperlinks in your TextFields.

To call a function in the same timeline as your TextField you would usually use something like:

myTxtFld.htmlText = "<a href='asfunction:myFunction,foo'>link</a>";

function myFunction(p)
{
trace(p);
}

See Macromedia Actionscript Dictionary

However, if you use a TextArea in the same timeline using the following won't work:

myTxtArea.text = "<a href='asfunction:myFunction,foo'>link</a>";

The reason for this is that the function is expected in the same timeline as the TextField. Within the TextArea component, however, the TextField used to display the text is a child of the component timeline. The timeline that contains your function is actually the _parent timeline of the one containing the TextField.

So use the following to get it to work:

myTxtArea.text = "<a href='asfunction:_parent.myFunction,foo'>link</a>";
