How to get return variable from coldfusion cfc page?

I have function that makes call to .cfc pag. I'm passing method and parameter along with the page name. Here is my code:

function callFunction(name){
    param = name;

    location.href = 'myTest.cfc?method=getRecords&userName=' + param;
}

Here is my cffunction on cfc page:

<cfcomponent>
    <cffunction name="getRecords" access="remote" returnformat="void">
        <cfargument name="userName" type="string" required="yes">

        <cfset myResult = "1">

        <cftry>
            <cfquery name="getResults" datasource="test">
                //myQuery
            </cfquery>

            <cfcatch>
                <cfoutput>#cfcatch#</cfoutput>
                <cfset myResult="0">
            </cfcatch>
        </cftry>
        <cfreturn myResult>
    </cffunction>
</cfcomponent>

My code doesn't give me return variable after I make a call to my function. I'm not sure what I'm missing in my code. If anyone can help with this problem please let me know.

This is how you would fetch the result of getRecords from the myTest.cfc component. 

var xhr = new XMLHttpRequest();
xhr.open('GET', 'myTest.cfc?method=getRecords&userName='+name);
xhr.send(null);

xhr.onreadystatechange = function () {
  var DONE = 4; // readyState 4 means the request is done.
  var OK = 200; // status 200 is a successful return.
  if (xhr.readyState === DONE) {
    if (xhr.status === OK) 
      var result = xhr.responseText; // 'This is the returned text.'
      //result will = 1 or 0.
    } else {
      console.log('Error: ' + xhr.status); // An error occurred during the request.
    }
  }
};

Not sure I've understood the question but are you looking for this... ?

function callFunction(name) {
  var target = 'myTest.cfc?method=getRecords&userName=' + name;

  location.href = target;

  return target;
}
