Re: Mixing CF and JavaScript.
You need to use AJAX. Basically, inside your lookUpUPC() function you
will make a call to a CFC that does the query and hands it back to the
javascript function to pupulate fields. Look into CFAjax.

I have a question on mixing CF and Javascript.
Say I have the following with an onBlur event:

Here is the JS for LookUpUPC()
function lookUpUPC(upc)
{
cfquery name=ckUPC datasource=#application.dsn#

/cfquery
cfif ckUPC.recordCount EQ 1
alert(UPC FOUND);
cfelse

/cfif
}
When LookUpUPC fires I get just the alert boxes that I coded in for
information purposes. I tried hard coding the query with a valid upc
in the database and still I get UPC not found.
So I must be doing something wrong but I am not sure what.
Can anybody shed some light?

In my opinion, this is one of the hardest things for new CFers to
understand. The key here is that the ColdFusion code is rendered
server-side and the javascript is executed client-side. For you, this
means that you can't do what you're trying to do the way you're trying
to do it. You're trying to execute server code in a client function.
You can accomplish the mission using AJaX, but not through inline
methods like these.
HTH.

So I must be doing something wrong but I am not sure what. Can anybody shed some light? -Jason ColdFusion runs on the server and Javascript runs on the client and the two don't mix. Ok, they can be made to look like they mix with Ajax and other techniques, but this isn't beginner stuff. The first way you could do what you want is with the CFWDDX... tag. It can take the query and change it into a JS array; you then look up the values in the array. This gets heavy if the recordset is larger and exposes all the data to the user, so it is not often used. -- Ian Skinner Web Programmer BloodSource www.BloodSource.org Sacramento, CA - | 1 | | - Binary Soduko | | | - C code.

Re: Mixing CF and JavaScript.
ColdFusion is server side. Once the page loads, CF is done.
JS is client side. You can't reference CF code inside of JS after the
page loads (not without getting AJAX-y).
you can create JS variables with CF:
script type=text/javascript
var myFoo = cfoutput#myQuery.foo#/cfoutput';
/script
if you view the source of that page after it loads, you'll see the JS
is valid. it's identical to using CF to create HTML.
However, once the page loads, you can no longer rely on CF to create
any client side code.
To do what you want, you'd use CF to create a JS array and your
onclick would use that array.

Re: Mixing CF and JavaScript.
Jason,
ColdFusion cannot be directly invoked from JavaScript without a interface to
call a service.
ColdFusion is processed and then the end result is passed through the web
server to your browser. At that point essentially, the page is static.
If you want interactivity, you have to call another page or service to
activate CF enabled templates. This is typically done in AJAX when using
JavaScript. You can do this also in Flash with Flex.

Re: Mixing CF and JavaScript.
I reviewed every one's response so far and I did like a single one. I would use a bakery analogy. For example CF is like a cake it gets baked first then the sweet buttery javascript icing goes last. The two don't mix well. To cut the layers you need a fork called AJAX bla bla bla. What you need to do is change things around and make Javascript into a cake too and CF the cake next to your new js cake of pure icing. When people eat your cake they dream of eating the CF cake. Those wishfull day dreams are called HXMLHttpRequest bla bla bla because JS longs to be a reasonable cake. ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:260430 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

I think for a guy who's on day 5...all that analogy is going to do is make him more confused and hungry for cake.

Re: Mixing CF and JavaScript.
To cake or not to bake, that is the question... Whether 'tis nobler in the kitchen to suffer the slings and arrows of outrageous icing or to bear arms against a sea of debugging - and by opposing, to make a sandwich... - Will Bakespeare -Jon*needs to eat some dinner* On Nov 14, 2006, at 7:00 PM, Dan Vega wrote: Im on year 5 and I am hungry for cake!

Re: Mixing CF and JavaScript.
Heres my .02 Do an iframe with the variable in the Url of the iframe. Do an onblur event on the field to reload the iframe. Put your Query and Display element in the iframe. I say this because if your doing a query on a DB with millions of records an aray might not be a good idea.? I use that approach for my data entry people for Addresses on the Zip Code to get County Contact info.
