You can add an event listener:

function tool(a, b) {
  console.log(a, b);
}
document.getElementById("link").addEventListener('click',
  function(e) {
    e.preventDefault();
    tool(2, 3);
  });
<a href="javascript:tool(1,2)" name="link" id="link" title="before click">click here</a>

Use what you want to do. But your question is not clear. As I understand I am giving your answer

Answer 1

function tool(a, b) {
    console.log(a, b);
    document.getElementById('link').href='javascript:tool(2, 3);';
}
<a href="javascript:tool(1, 2)" id="link" title="before click">click here</a>

Answer 2

function tool(a, b) {
    console.log(a, b);
    document.getElementById('link').href='javascript:tool('+(Number(a)+1)+', '+(Number(b)+1)+');';
}
<a href="javascript:tool(1, 2)" id="link" title="before click">click here</a>

You could update the href property of the anchor node.

function tool(a, b) {
    console.log(a, b);
}
document.getElementById('link').href='javascript:tool(2, 3);';
<a href="javascript:tool(1, 2)" id="link" title="before click">click here</a>
