AJAX UI Windows In Coldfusion 8
By Raymond Camden
I've been blogging about new ColdFusion UI controls in ColdFusion 8 and today I'm discussing CFWINDOW.
First - CFWINDOW does not - as you might guess - create a popup window. Which is probably a good thing. The last thing this world needs is another popup window. Instead the tag creates a "virtual" window that appears on top of your page. Let's take a look at a few examples.
At the simplest level, all you need to for a window is:
But if you run this, nothing shows up! Turns out that by default, windows are hidden. To make a window show up right away, you would do:
So this example begins by using cfimage to get information about an image. I use that information to supply a height to my window. I'm also using a few more attributes:
• Title - This sets the title of the window.
• Center - This centers a window.
• Modal - This makes the window have focus - it also does a cool "gray" effect on the rest of the page.
• Resizable - This lets you resize the window.
• Draggable - This lets you enable window moving (I turned it off)
• Height (and Width) - This lets you size the window.
You can see an example of this here.
