有没有办法JSON.stringify HTML dom对象? [JavaScript的]

[英]Is there a way to JSON.stringify an HTML dom object? [JavaScript]

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. 我正在尝试加载外部html文件并在正文中对内容进行字符串化处理,但如果不产生不希望的结果,似乎无法这样做。 Is there even a way to do this? 有没有办法做到这一点?

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: 但是我需要加载的是实际的div内容,例如:

//log: '<div id ='mydiv'>...</div>

What am I doing wrong? 我究竟做错了什么?

Your question is not very clear but I want to give it a try. 您的问题不是很清楚,但我想尝试一下。 Inspired from there: https://stackoverflow.com/a/7539198/1636522 . 从那里得到启发: https : //stackoverflow.com/a/7539198/1636522 Demo: http://jsfiddle.net/wared/fezc6tnt/ . 演示: 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': 通过将响应类型更改为“ DOMString”,我能够弄清楚这一点:

function buildAd(file){
    xhr.open("GET", file);
    xhr.responseType = "DOMString";
    xhr.send();
}
