Removing wrapper div without Jquery (raw javascript)

问题

I know there is a solution with Jquery called unwrap, but I am writing "raw" JavaScript. I didn't find any solution without jQuery.

I'd like to remove a div like so:

<div><div id="mydiv">Important text here</div></div>

After removal of "mydiv":

<div>Important text here</div>

What should I do, I'd like to know the theory.

Thanks in advance.

回答1:

shouldn't this line work

 document.getElementById("mydiv").outerHTML = document.getElementById("mydiv").innerHTML

See this JSBin Example (inspect the element)

回答2:

You need to use removeChild method for that:

var divToRemove = document.getElementById('mydiv').;
var tmpStr = divToRemove.innerHTML;
var parent = divToRemove.parentNode;
parent.removeChild(divToRemove);
parent.inerHTML(tmpStr);

回答3:

Try

​var el = document.getElementById('mydiv');
var text = el.innerText; //or el.innerHTML
    el.parentNode.innerHTML = text;
​

This would replace the html of mydiv's parent with the content of mydiv.
