Explanation:
This page uses an event handler created by Expression Web. To create it yourself, follow these steps:
- Add a button and then rt-clicked the button to edit the "Form Field Properties". Give it the name "btnGo" or something similar.
- Now, click Panels | Behaviors in Expression. This will display the behaviors window.
- Highlight your button. In the behaviors panel, choose Insert and select "Open browser window".
- This will create a new action and shows you that it will be called/triggered from an onClick event. Recall that we have done this manually in the past.
- Now double-click in the behaviors panel where it shows your new action (Open browser).
- This will open a dialog where you can choose the options you want the new window to have. See below.
- Choose OK. Now press F12 to run your page. When you examine the code, you will see that EW has added an onClick attribute to your button tag. It has given your event handler a name and also listed your properties that you chose.
- Now scroll up to the head part of your code. You will see a new function called "function FP_openNewWindow()". This function/method can now be used anywhere on your page. It has a bunch of code that will define how to open the new window. It looks messy to humans but the browser understands it perfectly. It looks weird because EW smushed all the lines together to save space.
- Try adding another button. Make it go to another website by adding a behavior to it just like you did with this one. You will discover that EW uses the same function it created the first time. It just passes it new arguments each time.
