new to java script (not to programming) Help with back/next navigation

Insider1984 · Nov 28, 2005

Hello everyone. I'm not new to programming but this is my first post in the javascript forum as I'm new to writing my own java script. My past experience has pretty much been modding correctly working java script.

anyway my question. I have a working menu system using a js file with the following inside of it:

Code:

/* Vision Menu items structure */
var MENU_ITEMS = [
	['Vision Basics', null, null,
		['Introduction', null, null,
			['Acronyms', '1-1.html'],
			['Terms', null],
			['Save Values', null],
			['Part Files Structure', null],
			['Image Naming Format', null],
			['Vision System Overview', null],
			['ImageJ/Matrox', null]
		],
		['CAD Files', null, null,
			['CAD File Locations', null],
			['DXF', null],
			['Modifications Needed', null],
			['Troubleshooting Common Errors', null]
		],
		['Vision Editor', null, null,
			['mini', null],
			['cad', null],
			['dxfx', null],
			['pini', null],
			['Field Of View Layout', null],
			['Placing Inspection Windows', null],
			['Scripts', null],
			['Masks', null],
			['Nominals', null],
			['Synthetics', null]
		],
		['Part File Cleanup', null, null,
			['remove tests without masks', null]
		],
		['Synthetic Images', null, null,
			['No Errors', null],
			['No Clipping', null],
			['Full Part Coverage', null],
			['All Edges Train', null],
			['Masks Are Places Correctly', null]
		]
	],
	['Advanced', null],
	['Expert', null]
];

It's pretty basic. The java script just makes a neat little menu from it. I use it currently to allow non programmers to make their own menus.

I'd like to extend the functionality of this one more by adding a next and back button either on the menu or at the bottom of the page that can help go "back" and "forward" through the list.

Seems like it should be fairly easy but without debugging (like I'm used to in C# for example) I don't have the confidence to just tinker until I understand and find the solution.

Please help if you can. Thanks!

But what is your actual problem? How are you stuck with the coding? Do you have errors, or are you after general pointers on how you might navigate through a 2D array?

but without debugging

Then get a JS debugger! One comes free with Firefox, MS offer a free downloadable one, and you've always got the likes of MS Visual Interdev, too - and that's just 3 off the top of my head - there are probably more if you look around.

Hope this helps,
Dan

It's very easy to do little JavaScript tests. I am constantly writing files called test.html with very minimal HTML in it to test an easy script:

Code:

<html>
<head>
<script>
function blahblah(arg1, arg2)
{
 //do something
}
</script>
</head>
<body>
<input type='button' value='click me' onclick='blahblah(1, 2)' />
</body>
</html>

Get over your fears! You will not break your computer!
