Answer 1

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>

Answer 2

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>

Answer 3

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>
