newbie quick ypSlideOutMenus question

[CH1LL1]

Hi there

I am using the funky ypSlideOutMenus on a website I am developing but want to slow down the speed the menus drop down. At the moment they drop down really quick, but have seen it slower on other sites.

Can any of you java gurus let me know what parameters to change?

Thanks!

I'm not familiar with them, but are you sure they're java and not javascript? Because a sliding website menu doesn't require Java, although it can be used for it.

[CH1LL1]

Ah sorry, just shows how much of a newbie I am - thought java was short for javascript

Code is js

[JPnyc]

Well without seeing the code, I would wager there's a setTimeout('functionName()', someValueInMilliseconds). someValueInMilliseconds is what you need to increase, it'll either be a number, or a variable set to a number.

Thanks, but it didn't seem to affect it in any way. It's on line 76. Perhaps someone could check over the code for me? Can someone tell me what the aniLen value does?

Try experimenting with these 2 values

ypSlideOutMenu.hideDelay = 50
ypSlideOutMenu.minCPUResolution = 10

[CH1LL1]

JPnyc

I have tried these already. HideDelay seems to make the drop downs stay open longer when you have moved on, whilst MinCPResolution doesn't seem to do anything!

Any other ideas

[JPnyc]

This is a mountain of code, and I don't have time to sift through it all. Have you tried to change this value in this line?
window.setTimeout(this.gRef + ".load()", 1000);

[CH1LL1]

Yeah, I have tried adjusting all the red values (red when viewing in Dreamweaver). I have compared the code to another website I did with the same menus and the values are identical but they slide out nicely.

I appreciate it's a mountain of code, but thanks for your suggestions anyhow.
