  • Flash AS3 clickTag specification
    • Create the button:
      - layer transparent button object over clickable area
      - Convert Button to symbol. In the properties panel, assign the button an instance name (such as “myButton”), which will be referenced in the ActionScript.
    • Add the ActionScript to the button:
      - Create a new layer, select the first keyframe in the layer and activate the Actions panel.
      - Copy and paste the code below. This defines the on click function. This function will be called upon once your button is clicked: 

      function onButtonClick(evt:MouseEvent):void{
      if (root.loaderInfo.parameters.clickTag.substr(0,5)==”http:” ||
      root.loaderInfo.parameters.clickTag.substr(0,6)==”https:” ){
      navigateToURL(new URLRequest(root.loaderInfo.parameters.clickTag),”_blank”);
      - Use the following code to connect the function above to the button you created. This tells flash what to do once the button is clicked. This code can be placed anywhere in your Actionscript code, but makes sense to attach it to your button layer. (In AS3, you can no longer attach Actionscript to the button itself, only to the layer):
      myButton.addEventListener(MouseEvent.CLICK, onButtonClick);
      multiple AS3 clickTags

      function onButtonClick1(evt:MouseEvent):void{
      navigateToURL(new URLRequest(root.loaderInfo.parameters.clickTag), ‘_blank’);
      function onButtonClick2(evt:MouseEvent):void{
      navigateToURL(new URLRequest(root.loaderInfo.parameters.clickTag2), ‘_blank’);

      function onButtonClick3(evt:MouseEvent):void{
      navigateToURL(new URLRequest(root.loaderInfo.parameters.clickTag3), ‘_blank’);

      button.addEventListener(MouseEvent.CLICK, onButtonClick1);
      button2.addEventListener(MouseEvent.CLICK, onButtonClick2);
      button3.addEventListener(MouseEvent.CLICK, onButtonClick3);

      flash notes:
      all flash ads must be served with a default image
      wmode must be set to transparent
      clickTag is case sensitive
