Video: Working with snippets

As you start working more and more with the code in {italic}Dreamweaver,{plain} you might find yourself using the same code over and over again on different pages, and typing the same code over and over again can be kind of tedious. Fortunately, {italic}Dreamweaver{plain} offers a way to save all those useful bits of code that you use every day as what are called Snippets. These are pieces of code, whether they're XHTML code, JavaScript, CSS, you name it, that you can add to your documents with the click of a button. {italic}Dreamweaver {plain}comes complete with its own set of predefined Snippets, and you can even create your own. In this exercise we'll take a look at how to add one of the predefined Code Snippets to your page, and also how to add you own Snippets to {italic}Dreamweaver.{plain} I'm going to come in here to the "About Us: Our Goal" text. I'm just going to click to the left of that, and I'm going to bring up my Snippets by coming over to my Files panel, and clicking on the Snippets panel.

Working with snippets

As you start working more and more with the code in {italic}Dreamweaver,{plain} you might find yourself using the same code over and over again on different pages, and typing the same code over and over again can be kind of tedious. Fortunately, {italic}Dreamweaver{plain} offers a way to save all those useful bits of code that you use every day as what are called Snippets. These are pieces of code, whether they're XHTML code, JavaScript, CSS, you name it, that you can add to your documents with the click of a button. {italic}Dreamweaver {plain}comes complete with its own set of predefined Snippets, and you can even create your own. In this exercise we'll take a look at how to add one of the predefined Code Snippets to your page, and also how to add you own Snippets to {italic}Dreamweaver.{plain} I'm going to come in here to the "About Us: Our Goal" text. I'm just going to click to the left of that, and I'm going to bring up my Snippets by coming over to my Files panel, and clicking on the Snippets panel.

You can see, the Snippets panel is broken down into all these different categories that you see here. We have Accessible snippets, Common snippets, Header snippets, JavaScript snippets; tons of different snippets that we can add to our page right away, In here, we also have Navigation, and we have Breadcrumb snippets. Now, breadcrumb, if you're not familiar with it, is just sort of a series of links at the top that show you where you are on your site. For instance, if we were on a products page, you might see some links at the top that say Our Products. Next to that might be Kettles and Teapots. Next to that might be Teapots.

So, you can just sort of follow your way across so you know exactly where you are on your site. It's called a breadcrumb. {italic}Dreamweaver{plain} comes with a built in generic breadcrumb snippet that I can use to add to my page. We have two of them, Angle brackets, you can see a preview up here, with a little angle bracket there. Or, we can use the colon as a separator, like so. I'm going to come down here and click the Insert button. And you can see what {italic}Dreamweaver{plain} has done here, especially if I switch to Split view here. It's inserted an entire table complete with place-holder links for adding your own breadcrumb style navigation.

You can see that it's created this table right here. For instance, if I wanted to I could come in here and change this to "About Us", and change this to "Our Company", "Our Policies", and then finally showing that we're on the Our Goal page, I can type "Our Goal". That's basically how a breadcrumb trail works. Now, the only problem I find is we don't really need an entire table to hold a breadcrumb trail. It can just be a single line of text.

You notice that I would now have to come in here and start playing around with these cell widths if I wanted these links to all be on one line. So I'm just going to select this entire table, and we'll delete that. Let's create our own breadcrumb navigation code that we can then save as a snippet to add to as many pages as we want. Let's go to Split view here. I'm going to put my cursor right before the h1 tag here, and I'm just going to give myself some space to work. Let's type some HTML code. We'll create a new paragraph. We'll put a link here, "a href=", and since we don't want to put a specific link here because we're creating just a generic breadcrumb trail, I'm going to put a hash mark here, or a null link, just make sure that this is a link, to make sure it doesn't go anywhere.

We'll close that anchor tag. We'll just use the same terminology, the generic Greeking terminology that {italic} Dreamweaver{plain} did for its breadcrumb navigation. So, we'll type in "Lorem", we'll close the anchor tag, like so. Type a space, a colon, another space, create another anchor tag, "a href". Just to save myself some time here, I'm just going to copy that code, like so, and let's just Paste that. This time it will be "Iapsum." Close that tag.

Another space, colon, space. Paste again. I'll just use the keyboard command of Command or Ctrl + V. "Oolar", close that tag, and one more: space, colon, space. This won't have a link, it will just be "Amit." We'll close that paragraph, like so. So, if I refresh my page on here, I can do that by clicking the Refresh button in the Properties Inspector here. You can see there's my breadcrumb trail, and I like the look of that much better, because now I don't have to worry about tables and table cells, and having all that extra code on my page.

I'm going to click somewhere in my breadcrumb trail. I can just select all the text here, but it's much easier to click somewhere in there and just the click the

tag to select the entire paragraph. Over here in the Snippets panel, I'm going to come down here and click the New Snippet button, which opens the Snippet dialog box, and we can give this a name, and I'll just call this "Standard Breadcrumb." Because this is an entire block of code, we're going to select Insert Block. We don't need to wrap that around anything and insert it after anything, because it's a freestanding bit of code. For the preview type, it will be Design, so we can actually see what it looks like.

That determines what we see in the Preview pane. If I had chose Code we would just see the code up here in the Preview, but if I want to see what it actually looks like, it'll show me the Design view. We'll click on OK, and you can see, there it is. So if I save, and close this page, and switch over back to my files and open up abouttea, I can just come in here, put my cursor before "About Tea: History," go back to snippets, and choose to insert my standard breadcrumb. There it is. That's how we create and work with snippets in {italic}Dreamweaver CS3.{plain} Again, it can be a big, big timesaver to create your own snippets if you find yourself using the same code over and over again.
