How can you change this
<div id='myDiv'><p>This div has <span>other elements</span> in it.</p></div>
into this
<div id='myDiv'>This div has other elements in it.</div>
hopefully using something like this
var ele = document.getElementById('myDiv');
while(ele.firstChild) {
replaceFunction(ele.firstChild, ele.firstChild.innerHTML);
}
function replaceFunction(element, text) {
// CODE TO REPLACE ELEMENT WITH TEXT
}
You can use innerText and textContent if you want to remove all descendant nodes, but leave the text:
// Microsoft
ele.innerText = ele.innerText;
// Others
ele.textContent = ele.textContent;
If you only want to flatten certain ones, you can define:
function foldIntoParent(element) {
while(ele.firstChild) {
ele.parentNode.insertBefore(ele.firstChild, ele);
}
ele.parentNode.removeChild(ele);
}
should pull all the children out of ele into its parent, and remove ele.
So if ele is the span above, it will do what you want. To find and fold all the element children of #myDiv do this:
function foldAllElementChildren(ele) {
for (var child = ele.firstChild, next; child; child = next) {
next = child.nextSibling;
if (child.nodeType === 1 /* ELEMENT */) {
foldIntoParent(child);
}
}
}
foldAllElementChildren(document.getElementById('myDiv'));
innerText in mind when you test on IE.If you're not opposed to using jQuery, stripping the HTML from an element and leaving only the text is as simple as:
$(element).html($(element).text());
You can just take the innerText
console.log(ele.innerText)
