Is there a way to JSON.stringify an HTML dom object? [JavaScript]
Question
I am trying to load in a external html file and stringify the contents within the body but can't seem to do so without it producing undesired results. Is there even a way to do this?
var xhr = new XMLHttpRequest();
function loadFile(){
xhr.open("GET", 'index.html');
xhr.responseType = "document";
xhr.send();
}
xhr.onload = function(data) {
myData = data;
myString = JSON.stringify(myData.srcElement.responseXML.body.children);
console.log(myString)
//logs: {"0":{},"length":1}
}
loadFile();
But what I need it to load is the actual div contents, ex:
//log: '<div id ='mydiv'>...</div>
What am I doing wrong?

Your question is not very clear but I want to give it a try. Inspired from there: https://stackoverflow.com/a/7539198/1636522 . Demo: http://jsfiddle.net/wared/fezc6tnt/ .
function string2dom (html) {
var iframe, doc;
iframe = document.createElement('iframe');
iframe.style.display = 'none';
document.body.appendChild(iframe);
doc = iframe.contentDocument || iframe.contentWindow.document;
iframe.parentNode.removeChild(iframe);
doc.open();
doc.write(html);
doc.close();
return doc;
}
var dom = string2dom(''
+ '<html>'
+ '<head>'
+ '<title>test</title>'
+ '</head>'
+ '<body>'
+ '<div id="test">allo la <b>terre</b></div>'
+ '</body>'
+ '</html>'
);
document.body.innerHTML = (
dom.getElementById('test').innerHTML
);

I was able to figure this out by changing the response type to 'DOMString':
function buildAd(file){
xhr.open("GET", file);
xhr.responseType = "DOMString";
xhr.send();
}
