How to parse text as JavaScript?
- by Danjah
This question of mine (currently unanswered), drove me toward finding a better solution to what I'm attempting.
My requirements:
chunks of code which can be arbitrarily added into a document, without an identifier:
[div class="thing"]
[elements... /]
[/div]
the objects are scanned for and found by an external script:
var things = yd.getElementsBy(function(el){
return yd.hasClass('thing');
},null,document );
the objects must be individually configurable, what I have currently is identifier-based:
[div class="thing" id="thing0"]
[elements... /]
[script type="text/javascript"]
new Thing().init({ id:'thing0'; });
[/script]
[/div]
So I need to ditch the identifier (id="thing0") so there are no duplicates when more than one chunk of the same code is added to a page
I still need to be able to config these objects individually, without an identifier
SO! All of that said, I wondered about creating a dynamic global variable within the script block of each added chunk of code, within its script tag. As each 'thing' is found, I figure it would be legit to grab the innerHTML of the script tag and somehow convert that text into a useable JS object.
Discuss.
Ok, don't discuss if you like, but if you get the drift then feel free to correct my wayward thinking or provide a better solution - please!
