Hello,
Originally I had this long post describing what I'm doing and where I'm
stuck and yadda yadda yadda. I think what it boils down to is that I
just don't know what the syntax of some of this js means.
I've searched several times in the past for what I consider "advanced"
js but all I seem to find are people who seem to still be living in the
late 90s.
Here's a specific example of something I don't quite understand:
(This comes from ajax_tables.js. I cut out some of the code for
brevity.)
loadFromDataAnchor = function (ev) {
ignoreEvent(ev);
var format = this.getAttribute("mochi:dataformat");
var href = this.href;
sortableManager.loadFromURL(format, href);
};
SortableManager.prototype = {
"initialize": function () {
// just rip all mochi-examples out of the DOM
...
// make a template list
...
// set up the data anchors to do loads
var anchors = getElementsByTagAndClassName("a", null);
for (var i = 0; i < anchors.length; i++) {
var node = anchors[i];
var format = getAttribute(node, "mochi:dataformat");
if (format) {
---------> node.onclick = loadFromDataAnchor;
}
}
},
...
};
Is 'node.onclick = loadFromDataAnchor' adding an onclick event to the
current node?
Then going to the definition of loadFromDataAnchor...
loadFromDataAnchor = function (ev) {
What is 'ev' and where does it come from? At this point I assume it
means "event" but I'm not positive. But even if it does, I'm not sure
how it's being used.
<phew>
Having avoided js like the plague for so many years has put me at a bit
of a disadvantage... but I think once I learn the basics I should be
good to go.
I guess this post is a bit long too. So much for rewrites. :)
Thanks,
Chris.
