How change all the href with a specific url?

I want to change all the urls of the href = "" that are in my home page, but it is a specific url.

Example:

<a href="mydomain.com/issues/resolve"> The issue </a>

Switch to:

<a href = "mydomain.com/issues/resolve/#thecontent">The issue</a>

I clarify that there is more than one with the same url, I want to change them all.

I have tried this without any visible result this I am doing with javascript:

$enlaces = document.getElementsByTagName("a");

                  for (let i = 0; i < $enlaces.length; i++) {
                    $enlaces2 = $enlaces[i];

                    if ($enlaces[i].href == 'mydomain.com/issues/resolve') {
                        this.href = 'mydomain.com/issues/resolve/#thecontent';
                    }

                    console.log ($enlaces2);

                  }

Solution

An <a> node has many properties.

Given:

HTML: <a href="https://www.example.com:80/this/is/the/path?foo=bar&bish=bash#myAnchor" >test link</a>,
javascript member representing the resulting DOM node: link,

then the properties of interest here are:

link.href https://www.example.com:80/this/is/the/path?foo=bar&bish=bash#testSector
link.hostname www.example.com
link.pathname /this/is/the/path
link.hash myAnchor

These and other properties are read/write.

So from the question, you appear to want to test a.hostname + a.pathname. If so then the following will do what you want:

$('a').each(function() {
    if ((this.hostname + this.pathname) == 'mydomain.com/issues/resolve') {
        this.hash = 'thecontent';
    }
});

You should see why testing the .href property didn't work.

Notes:

reading: a.hash returns a string including the leading #
writing: a.hash = "someString" does not require the hash.
there were historical differences between browsers in this regard but I think they are ironed out now (worth testing).
