Re: How do I reference Tapestry assets in JavaScript?

[Todd O'Bryan]

The component actually has tens of assets (maybe over a hundred), that, 
in a vanilla HTML page get loaded from the JavaScript by creating a 
URL. When it was turned into a Tapestry page, the person doing the 
porting figured out a kludge so that the JavaScript could use the 
Tapestry URLs to get to the assets. The problem is 3.0.3 needs MD5 
checksums to get at assets, so the kludge now fails.

I gather the way to deal with this is to rewrite the script so that all 
the assets are Tapestry-friendly and include ${ant-like-properties} in 
the JavaScript files. Unfortunately, the JavaScript file itself is 
quite a bit beyond me.

Thanks for the suggestions!

In order to get the valid URL for an asset, one has to call
String imageURL = getMyAsset().buildURL(cycle);
so, he would need to pass the cycle object to the script as well.
Or, he could do all this in java code, then set the url string in a 
field of his page class and then (in the .html):

<span jwcid="@Script" script="..." asset1Url="ognl: asset1Url" 
asset2="ognl: asset2Url"/>

I'm more than willing to code assets for all the images, other 
scripts, etc., but how do I reference those assets from inside the 
JavaScript components?

I may not be understanding your question, why not pass
the assets as symbols to the Script component like:
<span jwcid="@Script" script="..." asset1="ognl: assets.foo" 
asset2="ognl: assets.bar"/>
