How do I create a global function that I can call from my actionscript code in a Coldfusion Flash Forms page. Currently, all actionscript functionality on the page is linked to an event, for example, how do I create a GetCustomDate method that can be accessed by both cfsavecontents below. Currently, I have to do whatever functionality is required for GetCustomDate in each cfsavecontent definition.

For example:

<cfsavecontent variable="OnCustomDateClick">
   var customdate = GetCustomDate();
   //do other stuff
</cfsavecontent>
<cfsavecontent variable="OnNewDateClick">
   var newdate = GetCustomDate();
   //do other stuff
</cfsavecontent>

<cfinput onClick="#OnCustomDateClick#" type="text" name="customDate">
<cfinput onClick="#OnNewDateClick#" type="text" name="newDate">

The code may not be 100% accurate but you can get the jist of what I'm trying to accomplish. I really hope there is a way to do this.

--- UPDATE -------------------------------------------------------------------------------

Ok, so based on the comments so far, we are almost there except for one thing: Please excuse that the code is a little more comple开发者_JAVA百科x that the simple GetCustomDate example I gave previously. It was made simple to illustrate the problem.

Given the code below. When I try and call GetCurrency like so:

_global.GetCurrency('40346feb-feb9-11d8-995f-00c0df070000');
alert('Symbol After: ' + _global.GetMyResult());

The output is:

Symbol Before: $
Symbol After: Undefined

As you can see by the alert, the currencySymbol value ($) is set and accessible from within the GetCurrency method, but once it leaves that method, it's value is 'undefined'.

I'm not sure why this is happening. I have also tried returning the currencySymbol (this is commented out) variable from the GetCurrency method, but flash/actionscript doesn't seem to like the returning of values from the OnResult event.

How do I call this GetCurrency function so that once the function has completed, I have access to the result somehow??

<cfsavecontent variable="onLoad">
        <!--- Init --->
        _global.myResult;

        //create connection    
        var connection:mx.remoting.Connection = mx.remoting.NetServices.createGatewayConnection("http://<cfoutput>#cgi.HTTP_HOST#</cfoutput>/flashservices/gateway/");

        //declare service    
        var myService:mx.remoting.NetServiceProxy;
        var serviceName:String = '';

        var responseHandler = {};
        responseHandler.onStatus = function( stat: Object ):Void 
        {
           //if there is any error, show an alert 
           alert("Error while calling cfc:" + stat.description);
        }

        <!--- MyResult Get/Set --->
        _global.SetMyResult = function(result) 
        {
            _global.myResult = result;
            alert('_global.myResult' + _global.myResult)
        }       
        _global.GetMyResult = function() 
        {
            return _global.myResult;
        }

        <!--- Get Service Name --->
        _global.GetServiceName = function(serviceName) 
        {   
            var tServiceName:String = '';
            var tWebRoot:String = '<cfoutput>#Replace(Mid(request.site.webroot,2,Len(request.site.webroot)-1),'/','.','ALL')#</cfoutput>';

            <cfif request.site.webroot NEQ "">
                tServiceName = tWebRoot + '.' + + serviceName;
            </cfif>
            <!--- SALT --->
            tServiceName = 'pricelist.webroot.' + serviceName;

            return tServiceName;
        }       

        <!--- Get Currency --->
        _global.GetCurrency = function(currencyId)
        { 
            responseHandler.onResult = function( results: Object ):Void
            {
                var currencySymbol:String = '';

                if (results.length == 0) 
                {
                    alert('No details found!');
                } 
                else
                {
                    currencySymbol = results.getItemAt(0).currencySymbol;
                    _global.SetMyResult(currencySymbol);
                    alert('Symbol Before: ' + _global.GetMyResult());
                }
                //return currencySymbol;
            }           

            serviceName = _global.GetServiceName('components.currency');
            myService = connection.getService(serviceName, responseHandler );
            myService.getDetail(currencyId);
        }

        _global.GetCurrency('40346feb-feb9-11d8-995f-00c0df070000');
        alert('Symbol After: ' + _global.GetMyResult());
    </cfsavecontent>

Thanks


I'm not familiar with ActionScript at all, but after defining your function you can assign it to a different scope:

<cffunction name="GetCustomDate">
    <!--- do stuff --->
</cffunction>
<cfset request.GetCustomDate = GetCustomDate>

So after doing that, your code would change as follows:

<cfsavecontent variable="OnCustomDateClick">
   var customdate = request.GetCustomDate();
   //do other stuff
</cfsavecontent>
<cfsavecontent variable="OnNewDateClick">
   var newdate = request.GetCustomDate();
   //do other stuff
</cfsavecontent>

Sorry if I didn't address your question appropriately - like I said, I am not familiar with ActionScript.

Ok, per your comment that will not work. Try defining your function like this:

_global.GetCustomDate = function() { /* do stuff here */ }

And calling it like this:

<cfsavecontent variable="OnCustomDateClick">
   var customdate = _global.GetCustomDate();
   //do other stuff
</cfsavecontent>
<cfsavecontent variable="OnNewDateClick">
   var newdate = _global.GetCustomDate();
   //do other stuff
</cfsavecontent>


Why not put your GetCustomDate() actionscript function in a <cfformitem type="script"> before your cfsavecontents?

<cfformitem type="script">
function GetCustomDate():Date{
   // do stuff
}
</cfformitem>
