Creating effects with Spry behaviors

From: Dreamweaver CS3 Beyond the Basics

Video: Creating effects with Spry behaviors

One of the reasons Ajax is so popular with web developers is because it allows you to add cool effects like animation and fading items in and out, without the use of third party plug-ins. Adobe's Spry framework contains a full set of really cool effects and in this exercise, we'll see just how easy it is to apply them to your page. I have our Current.htm exercise file open. So if you are following along with me you are going to want to open this up. In our previous exercise we have completed our Accordion Widget, and we're going to add an effect to the image in the Accordion widget. So I am going to go on to a page and I am going to select the image. Now if you don't see the image, you will need to expand the first Accordion panel and remember you can do that by either clicking the Spry Accordion tab and clicking on the name of that, or clicking on the tab itself and then clicking on the eye icon that will show up on the right hand side.

Creating effects with Spry behaviors

One of the reasons Ajax is so popular with web developers is because it allows you to add cool effects like animation and fading items in and out, without the use of third party plug-ins. Adobe's Spry framework contains a full set of really cool effects and in this exercise, we'll see just how easy it is to apply them to your page. I have our Current.htm exercise file open. So if you are following along with me you are going to want to open this up. In our previous exercise we have completed our Accordion Widget, and we're going to add an effect to the image in the Accordion widget. So I am going to go on to a page and I am going to select the image. Now if you don't see the image, you will need to expand the first Accordion panel and remember you can do that by either clicking the Spry Accordion tab and clicking on the name of that, or clicking on the tab itself and then clicking on the eye icon that will show up on the right hand side.

Well you won't find these spry effects in the Spry toolbar. If I click on my Spry toolbar and open that up I really don't see anything up here relating to any type of effect. Remember a big part of Ajax is JavaScript. So these spry effects are located in the same place that you are going to access all your other prebuilt JavaScript in Dreamweaver, which is the Behaviors panel. So we're going to go to Window and choose Behaviors. If your Behaviors panel is not already open. Make sure you have your image or whatever object you are trying to apply the effect on, you need that selected first. Then I am going to go up to my Behaviors panel and click Add Behaviors. Well, in addition to the list that you're probably used to seeing, in Dreamweaver CS3 we're going to have an Effects flyout menu.

And we have Appear/Fade, we have a Blind Transition, Grow and Shrink, which is really useful for thumbnails and photo galleries. Highlight, Shake, Slide and Squish. So some really neat effects here that are JavaScript based. Well we're going to do the Appear/Fade. What I would like to have to happen is whenever I click on a painting to load the image up, I would like the image to kind of have a little bit of a fade effect to it as it fades in. So I am going to choose Appear/Fade and the Appear/Fade dialog box comes up. So every time you choose one of these effects you are going to have a dialog box. If you don't have something selected with your target element, any element on the page that has an ID or name attribute you're going to be able to target.

So I am going to stick with current selection because I have my image selected. I can choose an effect duration. I am going to have the effect last for one second. So notice that again it's in milliseconds. And I can have it fade in or appear. I am going to have it appear because I want it to fade in. Now when I choose Appear notice that I have the option bringing it up from a certain opacity and making it appear certain opacity. So I can actually have the final appearance at a lower opacity, which is a really neat effect. I think what we're going to do here, however, is I am going to go ahead and do 40% to 100%. Now feel free to modify it if you want to or try different settings.

That's the part of the fun of using these effects. I am of the school of thought though that less is more and going from 0%-100% is a really strong effect. So you get this big flash going on. I want it to be a little bit more subtle. Now I also do not want to select Toggle effect. The Toggle effect means the first time, it fades in; the second time, it fades out. It's very useful for showing and hiding objects. So you can have that Toggle going on and it remembers what it did in the previous time and it will just reverse it the next time. So I will say OK. Now notice that in our Behaviors panel we have our Appear/Fade effect. And we also have a default event. So these spry effects are driven by events. Right now OnClick is default event. Well that's not really what I want. I mean for that to work someone would have to actually click on the image to be able to see this effect. I want them to see the effect when it loads up.

So I am going to change that from OnClick. And we want to choose OnLoad. So to refresh this and then you'll be able to see it. So I am going to ahead and save my file. And again it's asking me, "Hey do you want me to copy these dependent files?" Now you may have already been doing some Spry development for a while and then later on the development you click Save and it asks you this again. Well it's because you have added another effect or another widget that requires a JavaScript file that you haven't copied over to your spry assets yet. So I am going to choose OK, it will copy that over and then I can test this in my browser.

So we're going to go ahead and preview this and now I'll scroll down my Accordion widget and I'll open this up and now every time I click on a painting I can see that I get that nice little neat little sort of flashing/fading effect. Now, there is no limit to how many of these effects you can add to your page. You could animate this while it's fading in. I am of the design school of less is more, however. I think if you overload the page with too many effects it begins to really overwhelm the actual information on the page. So I want to encourage you to experiment with all of those spry effects to find out which one is going to work best for your applications. In our next exercise, we'll take a look at hand coding spry content.
