Well, this would be easier and more Prototype-y if you used an event
listener instead of an onclick to open your function. If you did
that,
you would have access to the Event.element() function, which would
give
you an extended object reference to the element you clicked on. From
there it's very simple to update your input.
An event listener, you say. Hrm... I'll look into that.
Something like this:
<!-- include a fallback link for non-scripted browsers -->
<a class="edit_tags" href="/tags/edit/42">Edit</a>
document.observe('click',function(evt){
var elm;
if(elm = evt.findElement('a.edit_tags'){
cancel the click, since you're grabbing it in JS
evt.stop(); //
//do your magic here
var yourTagsAsText =['foo','bar','baz'].join(',');
elm.next('input').setValue(yourTagsAsText);
}
});
And then, whenever you've come up with your list of tags, all you
need
to do to to write the value back in is this:
elm.next('input').setValue(yourTagListAsText);
Aha ! I think this is what I was looking for. Thanks.
