What I am doing is calling a jQuery function which then uses a CFC method to
create my file. I am returning a message of how many files were created and
zipped up. I then want to present the user with the File Download box to
download the newly created file. It seems the cffunction does not like to have
the cfheader/cfcontent in the same function so I put it in its own function. It
appears the 2nd function call is returning the file contents to my $get result
set. If I call the function directly from a CFM page, the File Download box
will appear. Below is my cfc call and my cffunctions...
function exportPartsData(){
// Set a hidden variable to the selected rows lsa_aIds
getGridValues();
// Set variables
var aplsToUse = $('#selectedGrid').val();
var outputType = $('input:radio[name=fileType]:checked').val();
$.getJSON("services/Parts.cfc?ajaxTS=<cfoutput>#Now()#</cfoutput>&_cf_nodebug=true",
{method:'exportData',
idsToUse:idsToUse,
cache: false
},
function(data){
alert("'"+data+"'" + " Records Exported into a zip file into the
selected directory.");
// Present the user the a File Download Box
$.get("services/Parts.cfc?ajaxTS=<cfoutput>#Now()#</cfoutput>&_cf_nodebug=true",
{method:'openFile',
cache: false
},
function(data){
//alert(data);
}
);
}
);
}
....
CFFUNCTIONS...
<cffunction name="exportData" access="remote" returnformat="json"
returntype="any">
<cfargument name="idsToUse">
<cfset test = "this is my test file."/>
<cffile action="write" file="c:\test.txt" output="#variables.test#"/>
<cfset fileCount = ListLen(idsToUse)/>
<!--- Return the Count of files we created --->
<cfreturn fileCount />
</cffunction>
....
<cffunction name="openFile" access="remote" returnformat="plain"
returntype="Any" hint="Function which will present the download box">
<!--- Present the download box --->
<cfheader name="Content-disposition" VALUE="attachment;filename=test.txt">
<cfcontent type="application/octet-stream" FILE="c:\test.txt">
<cfreturn />
</cffunction>
