I have a whole bunch of pages that I need to parse through and add calculated
IDs to each image, based on the ID of its ancestor (might be parent,
grandparent or more) div which has the class of "page".
So that, for instance, this...
<div class="page" id="p_27">
... blah, blah ...
<img ... />
<img ... />
. .. blah, blah ...
<div ...>
<img ... />
</div>
</div>
<div class="page" id="p_28">
... blah, blah ...
<img ... />
<img ... />
. .. blah, blah ...
<div ...>
<img ... />
</div>
</div>
...would become this...
<div class="page" id="p_27">
... blah, blah ...
<img ... id="p_27-01 />
<img ... id="p_27-02 />
. .. blah, blah ...
<div ...>
<img ... id="p_27-03 />
</div>
</div>
<div class="page" id="p_28">
... blah, blah ...
<img ... id="p_28-01 />
<img ... id="p_28-02 />
. .. blah, blah ...
<div ...>
<img ... id="p_28-03 />
</div>
</div>
... etc., with the particulars having no regularity.
I've written a jQuery script that can do this dynamically with less code than
it takes to comment it.
$(function() {
$('div.page').each(function() {
//GET REFS TO ALL div.page ELEMENTS, WITH EACH ONE:
var theID = $(this).attr('id');
//GET THE ID OF THE DIV
var counter = 1;
//SET COUNTER TO ONE FOR FRESH INCREMENTATION
var imageID;
//DECLARE ImageID VARIABLE
$(this).find('img').each(function(counter) {
//GET REFS TO EACH DESCENDENT img OF THE DIV; WITH EACH
ONE:
imageID = (theID + "-" + (((counter += 1) < 10) ?
counter = "0" + counter : true));
//CONCATENATE THE DIV ID WITH THE COUNTER,
SEPARATED BY A HYPHEN,
WITH A LEADING ZERO IF NECESSARY,
SET THE VALUE OF imageID TO THE RESULT,
AND INCREMENT THE COUNTER.
$(this).attr('id', imageID);
//SET THE ID OF THE IMAGE TO imageID
});
});
});
But how might I go about getting the generated code for it into my source files?
I can write regular expressions, and I can AppleScript, but it's so much more
complex to deal with this sort of thing via string parsing than it is to
directly alter objects in the DOM.
Your suggestions are much appreciated.
