Replace attribute inside a tag

I am struggling to find a solution of replacing my attribute with another.

My HTML is:

<a href="#" external>link</a>

I want to replace "external" with target="_blank"

Is it doable?

You don't need jQuery for that.

Just iterate over the anchor elements with the external attribute using the selector a[external] and remove the external attribute and set the target attribute:

Example Here

Array.prototype.forEach.call(document.querySelectorAll('a[external]'), function(a) {
    a.removeAttribute('external');
    a.setAttribute('target', '_blank');
});

For what it's worth, if you want the jQuery alternative, use:

Example Here

$('a[external]').each(function () {
    $(this).removeAttr('external');
    $(this).attr('target', '_blank');
});

Correct me if I'm wrong, but this doesn't do what the OP describes, even if it does what he wanted. He said he wanted to replace external with target='_blank'. This removes external and adds target='_blank' regardless of whether or not that anchor had an external attribute. The below takes your code and checks for the existence of the external attribute before doing anything.

    Array.prototype.forEach.call(document.querySelectorAll('a'), function(a) {
    if (a.getAttribute("external") != null) {
        a.removeAttribute('external');
        a.setAttribute('target', '_blank');
    }
});
