image preload script 1

[gollyg]

Hi,

I've been trying to write something to simplify the preloading for my buttons. There are two button states and they are named button.gif and button_o.gif (where button is a unique name for the button). So the code needs to introduce button as a new image and set the source property. But it doesn't! Any help much appreciated.

navImgs = 
["commit","contact","dates","draw","entry","finals","links","results",
"rules","scores","teams","winners"]


	buttons = new Array()
	buttons_o = new Array()

for (i in navImgs)
	{

		buttons[i] = new Image
		buttons_o[i] = new Image		
		
		
		buttons[i].src  = "images/" + navImgs[i] + ".gif"
		buttons[i].name  = navImgs[i]
		buttons_o[i].src  = "images/" + navImgs[i] + "_o.gif"
		buttons_o[i].name  = navImgs[i] + "_o"

	}

A good friend of mine FlatHead asked the same question on the HTML forum a few weeks ago, check out what responses he got.

I'm not sure but I think you need to define the array elements before you can assign an object to them, had a similar problem a few weeks ago.
Try declaring the arrays:
var buttons = new Array [navImgs.length]
ver buttons_o = new Array [navImgs.length]
Hope that helps.

Thanks alot for your replies. It's great that people actually want to help out! I think I found the problem - I forgot the () after declaring the new image objects. Seems to be working now.

Thanks again
