json get not access returning as undefined

I am currently doing the following with some jQuery,

    $(".template-choice").live("click", function(event){$.post($(this).attr('href'), function(data) {
                console.log(data);
            $('.textarea textarea').val(data.letter_template_content);
     });
     event.preventDefault();
});

As you can see I trying to insert the JSON var into a textarea however my data.letter_template_content is returning as undefined below is my JSON object,

{"template":[{"letter_template_id":"1","letter_template_name":"Change of address","letter_template_content":"<p style=\"font-weight: bold;\">[Your Name] <\/p><p style=\"font-weight: bold;\">[Address] <\/p><p style=\"font-weight: bold;\">[Town, City] <\/p><p><span style=\"font-weight: bold;\">[Post Code] <\/span><br><\/p><p><br><\/p><p> <\/p><p>[Recipient Name] <\/p><p>[Job Title] <\/p><p>[Company Name] <\/p><p>[Address] <\/p><p>[Town, City] <\/p><p>[ Post Code] <\/p><p> <\/p><p> <\/p><p>Dear <span>[Recipient Name]<\/span>: <br><\/p><p><br><\/p><p> <\/p><p>This letter is to inform you that I have a new mailing address.

how do i access the letter_template_name key?

That's because data.letter_template_content doesn't exist.

Try:

data.template[0].letter_template_id
data.template[0].letter_template_name
data.template[0].letter_template_content

Your (very nicely formatted JSON, may I add), would look like this in a nicely formatted world:

{
    template: [
        {
            letter_template_id: 1,
            letter_template_name: "Change of address",
            letter_template_content: "lots of html",
        },...
    ]
}

this one is correct

data.template[0].letter_template_content
