How do I clear the content of a div using JavaScript? [closed]

Closed 2 years ago.
document.getElementById('test').innerHTML = '<h1>Hello World</h1>';
Is there anyway that I can remove everything the code above put between two HTML tags?
I gather you want to remove the text between the <h1> and the </h1>. Simple:
const test = document.getElementById('test');
const child = test.firstChild;
child.innerHTML = "";

Something like this should do the trick. If you have further questions feel free to ask them :)
var x = document.querySelectorAll("a");
x.forEach(function(element){
var link = element.href;
console.log(link)
element.href = link + "?max-results=7";
console.log(element.href);
});

How do I concatenate a string with a variable?
(5 answers)
Closed 3 years ago.
This is basic ,
I can show or hide a class with :
$('.blink').show();
but I would like to do the same with a parameter so
var a = "blink";
$(a).show();
will not work obviously and I couldn't find the keywords to look for this in google.
You need to append a dot when you use that variable so that the $ will consider it as a class selector:
var a = "blink";
$('.'+a).show();

I want to translate an input from an API like this
<p>Communication that doesn’t take a chance doesn’t stand a chance.</p>
into something like this
"Communication that doesn’t take a chance doesn’t stand a chance."
I understand that html could translate this but I don't know how to translate this directly for use in javascript
Insert it into an element as HTML, and read it back out as text.
var elt = document.createElement('div');
elt.innerHTML = apiResponse;
alert(elt.textContent);

JavaScript DOM remove element
(4 answers)
Closed 8 years ago.
Ok I've been so spoiled with Jquery that I don't even know how to remove an element anymore with plain Javascript.
So I have this which I would like to remove with Javascript.
Any help appreciated.
Try this
function RemoveElement(elemID) {
var elem = document.getElementById(elemID);
if (elem.parentNode) {
elem.parentNode.removeChild(elem);
}
}
Node.removeChild is the method, see documentation here: https://developer.mozilla.org/En/DOM/Node.removeChild
Example:
var parent = document.getElementById("mydiv");
var child = document.getElementById("other");
parent.removeChild(child);
like:
container.removeChild(child);
