I have a form I built wherein I am binding several fields to one cfinput and hitting a cfc I built that pulls data from a web service. I am struggling in figuring out how to get the fields to fill in with the binding value once I click a button. Here's the scenario...the end user fills in the field, clicks a button and several other fields get filled in from the cfc that hits the web service. I have tried the following to no avail...

</cfform>

I have even tried playing with the cfajaxproxy tag and the @4642326 event. I feel like I am close. If someone could educate me/point me in the right direction, I would appreciate it.

Thanks,

~Clay

When I add the @click in the above bind attribute, it works when I click in the appropriate fields, but I cannot seem to figure out how to run the bind when clicking the button.

ok...I figured it out and thought I would post my solution in case someone else runs into this issue...

(my solution is based of of this link)

cfajaxproxy tag to tie cfc to page via JSON

<cfajaxproxy cfc="proxy" jsclassname="proxy" />

Script that runs the method within the cfc and uses the setCallbackHandler function to return the result. The we can set the result equal to the value utilizing the DOM.

<script>
          function getYearvin(source) {
                    var instance = new proxy();
                    instance.setCallbackHandler(getYearvinSuccess);
                    instance.getYearvin(source);
          }
          function getYearvinSuccess(result) {
                    document.getElementById('year').value = result;
          }
</script>

Here is the form...

<input type="text" name="source" id="source" value="" />
<button name="vinDecode" onClick="getYearvin(getElementById('source').value)">Get Year</button>
<br><br>
<input type="text" name="year" id="year" value="" />

FYI...I wrote a quick blog post concerning this...http://webolutiondesigns.com/blog/ajaxcfcs-json-and-other-geeky-stuff/
