如何将动态创建的输入（或文本框）值发送到iframe，并在iframe中将其显示为HTML？

Question

How do I send my dynamically created input (or textbox) values to an iframe and show it as HTML inside the iframe?

I'm trying to do it with the code below (on JSFiddle), but other solutions would be nice too. Thanks. Jquery is fine also.

Here's the HTML:

<a href="#" id="new" rel="create">new</a><br>
<a href="#" id="another" rel="create">another</a><br>

<input id="thisButton" type="button" name="Display" value="Edit HTML Below then Click to Display"/>

<iframe id="iframetest" src="" style="background: White;"></iframe>

Here's the Javascript:

var counter = {};

var myHTML = {
    'new': '<input id="test%n" name="test" value="<b>blah</b> blah blah %n">',
    'another': '<input id="another%n" name="test" value="<b>cool</b> COOL! %n">'
};

var htmlForId = {
    'foo': ['a','b','c'],
    'bar': ['d','e','f']
}

var createEls = document.querySelectorAll('a[rel=create]');
for(var i = 0; i < createEls.length; i++) {

  createEls[i].onclick = create;
}

function create() {
    var id = this.id;

    var div = document.createElement('div');
    div.className = 'create';
    if (counter[id]===undefined) { counter[id] = 1; }
    var thecurrentid = counter[id];
    div.id = id + counter[id]++;

    if (div.id in myHTML) {
        div.innerHTML = myHTML[div.id].replace(/%n/g, thecurrentid);
    } else if (this.id in myHTML) {
        div.innerHTML = myHTML[this.id].replace(/%n/g, thecurrentid);
    } else {
        div.innerHTML = div.id;
    }
    document.body.appendChild(div);

    return false;
}

var myArray = [
    'b<strong>l</strong>a bla bla', // index 0
    'foo', // index 1
    'test' // index 2
];
function appendArray(a) {
    for(var i = 0; i < a.length; i++) {
        var div = document.createElement('div');
        div.className = 'loop';
        div.innerHTML = a[i];
        document.body.appendChild(div);
    }
}

you can access the document object of iframe using contentDocument

document.getElementById("thisButton").onclick = function(){
    var html = "<b>Dynamic Content</b>"; //TODO: get the value dynamically from textbox
    document.getElementById("iframetest").contentDocument.body.innerHTML = html;
};
