How do you execute an 'if' statement with html

[allywally]

How do you execute an if-statement on a drop down box. I have to do a camera website and basically there's a drop down box for camera manufacturer, if an option is clicked then reaults are displayed thats what i'm going for

Impossible to do through HTML or CSS

Head over to the Javascript/AJAX forum.

Or, indeed, the PHP forum

The if statements in html are really basic.

I've only ever used them to detect the browser and browser version. not sure if they can be used to do anything else, as i've never tried to do anything else with them.


IF statements need to be inside HTML comments, i.e.

[HTML]<!-- -->[/HTML]

Interent Explorer is the only browser that will run these IF statements as it is the only broswer that executes HTML comments. All the other browsers ignore HTML comments.

You can use the if statements to include other stylesheets or javascript files. based on whether the browser is internet explorer and the version

e.g.

[HTML]<!--[if lt IE 7]>
<link rel="stylesheet" href="css/styles-lessthan7.css" type="text/css" />
<![endif]-->

<!--[if IE]>
<link rel="stylesheet" href="css/styles-ie.css" type="text/css" />
<![endif]-->[/HTML]
