jquery check if radio button is checked and then check if tickbox is checked

Question

Hi, I have a two part form which I have developed. One is for existing members and one is not.

On one of the forms I have a checkbox which will need to be checked before they can proceed, to determine that they are on the correct form. I will use the radio button which hides and unhides forms.

However when I try to get a handle on if the radio button is checked and then checking to see if the checkbox is checked I get nothing returned.

Can someone help me implement this? My JS is below or view my JSFIDDLE:

$(document).ready(function(){

    var check;   

    if($("input:radio[name=existingpartner]").is(":checked")){

        // Example 3 - With jQuery prop  
    $("#test-with-prop").on("click", function(){
        check = $("#mycheckbox").prop("checked");
        if(check) {
             alert("Checkbox is checked.");
        } else {
            alert("Checkbox is unchecked.");
        }
    }); 
});

This is the best and the most recommended way when using jQuery:

if( $('#radio').is(':checked') ){
    alert("Radio Button Is checked!");
}
else{
    alert("Radio Button Is not checked :( ");
}
