The code
var txt = '<div id="hi">fe</div><div id="h2">fe</div><div id="hj">fe</div>'
var parser = new DOMParser();
var temp_node = parser.parseFromString(txt, "text/html").documentElement;
console.log(temp_node)
This code results in the full html document, this is including
<html><head></head><body>
<div id="hi">fe</div>
<div id="h2">fe</div>
<div id="hj">fe</div>
</body></html>
What if I want only the <div id="hi">fe</div><div id="h2">fe</div><div id="hj">fe</div> part? How can I do it?
And, if I want to append all nodes, is there a way to do it without a loop?
parentNode.appendChile(temp_node) // add the entire code
parentNode.appendChile(temp_node.firstElementChild.nextElementSibling) // add the parent <body> and the other layers inside
parentNode.appendChild(temp_node.firstElementChild.nextElementSibling.childNodes) // doesn't do the trick, it plains about not being a "node", I guess I'd need an "appendChilds" function that allows to add many nodes at once
*What I'd wish, if parentNode is <div id="parent">
<div id="parent">
<div id="hi">fe</div>
<div id="h2">fe</div>
<div id="hj">fe</div>
</div>
But I get
<div id="parent">
<body>
<div id="hi">fe</div>
<div id="h2">fe</div>
<div id="hj">fe</div>
</body>
</div>

Reset to default 9Use childNodes
console.log(temp_node.childNodes[1].childNodes[0]);
or querySelector
console.log(temp_node.querySelector("#hi"));
JSFiddle demo
Update
or innerHTML
console.log(temp_node.querySelector("body").innerHTML);
JSFiddle demo
You can use .body instead:
parser.parseFromString(txt, "text/html").body
When you use the property .documentElement as you did in your code, it returns the following:
Returns the Element that is a direct child of the document. For HTML documents, this is normally the HTMLHtmlElement object representing the document's
<html>element.- MDN
Other properties exist on the Document, .body is one of which. Using .body (instead of querySelector()) will give you fast and direct access to the body of your HTML content, which you can then use .innerHTML on to get its inner contents as a string:
See working example:
const txt = '<div id="hi">fe</div><div id="h2">fe</div><div id="hj">fe</div>'
const parser = new DOMParser();
const temp_node = parser.parseFromString(txt, "text/html").body;
console.log(temp_node.innerHTML);发布者：admin，转转请注明出处：http://www.yc00.com/questions/1741066234a4300622.html
