Question

How can I add the href attribute to a link dynamically using JavaScript?

I basically want to add a href attribute to

Answer 1

First, try changing <a>Link</a> to <span id=test><a>Link</a></span>.

Then, add something like this in the javascript function that you're calling:

var abc = 'somelink';
document.getElementById('test').innerHTML = '<a href="' + abc + '">Link</a>';

This way the link will look like this:

<a href="somelink">Link</a>

Answer 2

document.getElementById('link-id').href = "new-href";

I know this is an old post, but here's a one-liner that might be more suitable for some folks.

Answer 3

var a = document.getElementById('yourlinkId'); //or grab it by tagname etc
a.href = "somelink url"

Answer 4

More actual solution:

<a id="someId">Link</a>

const a = document.querySelector('#someId');
a.href = 'url';

Answer 5

I assume you know how to get the DOM object for the <a> element (use document.getElementById or some other method).

To add any attribute, just use the setAttribute method on the DOM object:

a = document.getElementById(...);
a.setAttribute("href", "somelink url");
