How to insertBefore() element in body tag?

rated 0 times [ 22] [ 5] / answers: 1 / hits: 80781 / 13 Years ago, mon, may 16, 2011, 12:00:00

I am trying to use insertBefore in js like this:

var p = document.createElement(p);

p.innerHTML = test1;

document.body.insertBefore(p, null);



var p = document.createElement(p);

p.innerHTML = test2;

document.body.insertBefore(p, null);

But that would add the last p element just before the close of the body tag, how could I use it so it will be added to the top when it opens? So the last element added will be the first element inside the body tag.

I tried:

document.body.insertBefore(p, document.getElementsByTagName('body')[0]);

But firebug shows:

Node was not found code: 8

You can get the first child of the body element with the firstChild property. Then use it as the reference.

const p = document.createElement(p);

p.textContent = test1;

document.body.insertBefore(p, document.body.firstChild);

I modernized your code for reasons :)
