Callback Functions: Taking a Variable Literally

[BooYaKaSha]

Long story short, I have this script:

for (i = 1; i <= currentType.length; i++)
// (sic)
{
this[&quot;piece&quot; + i].onRollOver = function()
{
getDescription(i);
descriptionBar.gotoAndPlay(&quot;over&quot;
}
// (sic)
}

The &quot;getDescription(i)&quot; part won't work, and I understand why, but how can I modify that to make it work. I need &quot;i&quot;'s value to be taken literally right then and there, not when the callback gets executed.

I've tried things like &quot;eval(i)&quot;, &quot;function() {return i}&quot; and &quot;i.toString()&quot; to no avail.
Thanks a million for your help.

what does the function getDescription look like

function getDescription(whichPiece)
{
descriptionBar.slider.title = currentType[whichPiece].title;
descriptionBar.slider.subtitle = currentType[whichPiece].subtitle;
descriptionBar.slider.summary = currentType[whichPiece].summary;
descriptionBar.slider.description = currentType[whichPiece].description;
}

currentType is a reference to an object that was parsed from an XML file.

I figured out one solution:
getDescription(this._name.substr(this._name.length - 1, 1));

But if you know of a more elegant solution I'm definitely all ears. Thanks

untested but given your solution im sure this will work

for (i = 1; i <= currentType.length; i++)
// (sic)
{
this[&quot;piece&quot; + i].onRollOver = function()
{
getDescription();
descriptionBar.gotoAndPlay(&quot;over&quot;
}
// (sic)
}

Are you sure that's right?

I need to pass getDescription() a number.

 

[billwatson]

yes im sure but as i said i aint tested it

I think the problem with Bill's code is that there was an 'i' in square brackets in there and the site has treated it as an 'italics' tag. Can you repost Bill with the code inside

tags?

 

[wangbar]

Hmmm.. the site also parses 'code' tags of course...

That should have read:

the code inside '[''code' ']' tags?

 

[billwatson]

well spotted wangbar thats exactly what i had

(square baracket i sqr.brk)

OH, sorry Bill, was wondering why half of it was in italics

To make sure I am trying the right thing:

for (i = 1; i <= currentType.length; i++)
// (sic)
{
this[&quot;piece&quot; + i].onRollOver = function()
{
getDescription();
descriptionBar.gotoAndPlay(&quot;over&quot;
}
// (sic)
}

I tried the above and unfortunately it did not work.

 

[billwatson]

thats what i expected to work

well at least you have your original solution

Maybe Bill will someday learn how to use &quot;code&quot; tags here on TT!
Read the last note in &quot;Process TGML&quot; on the bottom of the post window... If you can find it!
