How to use jquery trigger anchor's default click event?

Question

Suppose I have an anchor in my page like :turn to header then I also set a button in my page

Answer 1

Please see this answer.

Instead of trying to trigger the click event, try setting the window.location property:

window.location = '#header';

Or perhaps:

$("input").click(function() {
  window.location = $('#anchor').attr('href');
});
