Coldfusion CFC Return JSON display in Jquery, how do I handle multiple records from CFC and display in Jquery?

Question

I need a way to grab the json return from coldfusion and display it in jquery I can display the first result fine, but if more that one record comes back I am stuck Here is my cfc

<cfquery name="users" datasource="#thedb#">
In this query I can get 1 record to 25 or even more results         
</cfquery>

Here is my out put to jquery, not sure if this is a good way to do this, but.... this is how I handle mutliple records right now.

<cfset var user = structNew()/>

<cfset thenumber = 1>   
        <cfloop query="users"> 
        <cfset user["newrequestor#theNumber#"] = users.requestor/>
        <cfset user["newrequestorusername#theNumber#"] = users.requestor_username/>
        <cfset user["newrequestorphone#theNumber#"] = users.requestorphone/>
        <cfset user["newrequestoremail#theNumber#"] = users.requestoremail/>
        <cfset user["newthedate#theNumber#"] = users.thedate/>
        <cfset user["newapproved#theNumber#"] = users.approved/>
        <cfset user["newcomments#theNumber#"] = users.comments/>
        <cfset user["newviewed#theNumber#"] = users.viewed/>
        <cfset thenumber = thenumber + 1>
        </cfloop>

<cfreturn user>

End of CFC

Here is my jquery, I have it manually set to grab first record... not sure how to loop over to get all records returned.

Here I pass my arguments to the cfc to get my result. works great

thedata = instance.getSearch($("#therequestor").val(), $("#fromDate").val(), $("#toDate").val(), $("#theapproved").val(), $("#theroom").val());

Next I build a row in jquery to handle my first record, manual setting not dynamic.

var new_Return = '<tr id="newReturn"><th style="text-align:left;" id="first">Request Date:</th><td>'+thedata.newthedate1+'</td><td>&nbsp&nbsp&nbsp&nbsp</td><th style="text-align:left;" id="first">Requestor:</th><td>'+thedata.newrequestor1+'</td><td>&nbsp&nbsp&nbsp&nbsp</td><th style="text-align:left;" id="first">Approved:</th><td>'+thedata.newapproved1+'</td><td>&nbsp&nbsp&nbsp&nbsp</td><th style="text-align:left;" id="first">Viewed:</th><td>'+thedata.newviewed1+'</td></tr>';
        $("#theReturnFormTable").append(new_Return)

Displays first result in my div tag great, how can I loop over if I have multiple records Example thedata.newrequestor1 is my first record

then I could have more many more

thedata.newrequestor2 is my 2nd thedata.newrequestor3 is my 3rd etc. on and on

How can I handle this in jquery, or do I have to start different in coldfusion cfc??

Answer 1

You could just call the remote function and let ColdFusion serialize the query object to JSON? (notice returnFormat="JSON")

<cffunction name="getUsers" access="remote" returnType="query" returnFormat="JSON">
   <cfquery name="users" datasource="#thedb#">
       In this query I can get 1 record to 25 or even more results         
   </cfquery>
   <cfreturn users>
</cffunction>

JSON formatting will look like this:

{"COLUMNS":["NEWREQUESTER","NEWREQUESTERUSERNAME"],"DATA":[["1","JOHN DOE"],["2","JIM DOE"]]}
