Use of HTML5 custom data attribute for AJAX response

I have never used HTML5 much and so am not aware of its limitation.

But I have heard there is a useful custom data attribute which has got added. So my question is, can I use this for AJAX response handling? By that I mean, say I have coded some placeholder divs with data attributes.

Now can I parse this JSON response to fill up the div elements easily. Or is there another quicker way?

Main thing i开发者_C百科s HTML structure would be separate and json response will only contain data.
