how to get parameters from component to javascript

Hi Folks,

I have this component... TransparentTextImage

BlahBlah.tml
<img t:type="transparentTextImage" t:id="transparentTextImageComponentId" id="transparentTextImageComponentId"
    src="${photoLink}" alt="${currentObject}" width="200" height="160" 
    title="${currentObject.photo.fileName}"
    model="currentObject"
    image="${photoLink}"
         topLeftText="${currentObject}.transparentText"
         topRightText="topRightText"
         bottomLeftText="bottomLeftText"
         bottomRightText="bottomRightText"
         centerText="centerText"                                        
/>

I am attempting to operate some integrated JAVASCRIPT and inside the javascript I want to setup local var for these...
         topLeftText
         topRightText
         bottomLeftText
         bottomRightText
         centerText

Does anyone know how to get these from within the javascript?

Thanks

The client side only knows what the server side tells it. You must pass
this down to the client in some way. Modern thinking is to write data-
attributes into the element.

Alright, I am up to speed on your suggestion.

I faired well with the T4 style... and was able to get fairly granular by indexing appended loop indices onto the and of function names at render time in order to customize specific javascript to items on each individual iteration within loops.

Not sure if I can do that now. But I will try.

keepin rolling with the punches

Best regards

Thanks Howard,

Would you be referring to JSon ?

I might be happy to hear that... just looking for a confirmation.
