I wanted to know if somehow it could be done that when I clicked with href, a function would be executed and how it would be (having jquery and js available). I had something like that but it does not work, thank you very much.
<a href="funcion(x)">Y</a>
It is wrong, the href property in the <a> tags is used to determine the link to which you would redirect the link, for example:
<a href="https://www.google.es/">Google</a>
If what you want is that when you click on the link to execute a JS function you have to use the property onclick :
<button onclick="Funcion()">Hago algo</button>
