Question

I’m trying to call an as3 function from a dynamic textfield.

I’ve tried this:

function showPopupWindow(){
    trace("it works");
}

var texts="Hello world. <a href='#' onclick='showPopupWindow()'><u>This is a function call</u></a>";

text_txt.htmlText = texts;

You’ll have to use the TextEvent.LINK event. First, you’ll need to create a link that points to a URL Flash can recognize by prepending event: to a name. For example, you might have a piece of text like this:

textField.htmlText = "<a href='event:playMovie'>Play.</a><br />" + 
                     "<a href='event:stopMovie'>Stop.</a>";

Then, you need to add a listener for the event. You can use the TextEvent::text property to determine what link was clicked. Using the above code, here’s a sample handler:

textField.addEventListener(TextEvent.LINK, handleLink);

function handleLink(evt:TextEvent):void {
    switch (evt.text) {
        case "playMovie":
            play();
            break;
        case "stopMovie":
            stop();
            break;
    }
}
