I'm curious if this is a standard way of doing this with Coldfusion + $.ajax. It seems that my code gets a little bloated from this way. And again my question is really just to explore other ways to not have full page refreshes.
<!DOCTYPE html>
<html>
<head>
	<title></title>
</head>
<body>


<div class="loadData"></div>

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

<script>
$(document).ready(function() {
	$(".loadData").load("mydata.cfm");
});

I might have other functions here that specifically work for a few unrelated items in the "loadData" content area.

</script>


</body>
</html>

#### mydata.cfm 

<!--- I usually create .cfc's for retrieving data but for simplicty I'm adding it here --->
<cfquery>
	SELECT *
	FROM TABLE
</cfquery>

<cfoutput>
#data# I could have functionality like deleting or updating to where I utilize jquery as well.
</cfoutput>

<script>
     I might have functions here that seem to only specifically work for this pages functionality here. Which makes sense (DOM) but I'm just exploring other ways to possibly handle the ajax awesomeness as I've mentioned above.
</script>

are you asking if using $(".loadData").load("mydata.cfm"); to populate elements is ok - or is there a better way?

my opinion is that it is ok.

myself i might do the following instead though:

<div class="loadData"><cfinclude template="mydata.cfm"></div>
then to refresh it on some event i would reload it using using the $("#someelement").on('click', function() { $(".loadData").load("mydata.cfm"); } }); ...
(that's just for example)

OR if your question is different than that could you clarify please.

good luck ...

The way @dgrafx told you and you working is the best method if you want to implement ajax with coldfusion.

If you want to explore other ways, use javascript mvs frameworks like AngularJS, KnockoutJS, Batman for writing same code in more MVC manner so you can get the relevant Output

ok, thx. Just two questions: 1. Is it common to have specific javascript functions for say your "mydata.cfm" on that page? Seems like I have to add in some functions specifically used on that page at the bottom. Ideally it would be nice to just have one main scripts.js file for less clutter in the head or footer but I'm guessing the DOM of mydata.cfm loads differently so maybe that's just how it is.

<cfoutput> stuff...

<script>
 Do stuff...
</script>

2. Your method of the ".load" what advantage is that over the way I'm doing it? Just curious.

Thank you!

1. yes - create a master .js file - less clutter - stay organized
plus you do not want to add js functions in your mydata file - spaghetti code ya know ...
just like in CF you want to keep your functions in a cfc and all your cfcs in one location

2. using .on(...) will allow you to access dynamically written elements.
this may be a problem you've possibly encountered in the past ...
