Answer 1

You've misidentified the problem.

jQuery('a[href*="15628"]') is finding the element just fine (I haven't checked the others).

However, the value you assign to the onclick property must be a function and you are assigning a string.

You should use the on() method to assign event handlers when you are using jQuery though.

Answer 2

You can do this several ways, but your binding of the event is incorrect. See these examples from your code and one I added.

 console.log(jQuery('a[href*="15628"]').length); console.log(jQuery('a[href="https://stackoverflow.com/?page_id=15628"]').length); jQuery('a[href="https://stackoverflow.com/"]').on("click", function(event) { event.preventDefault(); event.stopPropagation(); console.log('home link'); // window.location.href = 'https://stackoverflow.com/?page_id=15628'; return false; }); jQuery('a[href*="15628"]').on("click", function(event) { event.preventDefault(); event.stopPropagation(); console.log('no ajax1', $(this).attr('href')); // window.location.href = 'https://stackoverflow.com/?page_id=15628'; return false; }); jQuery('a[href="https://stackoverflow.com/?page_id=15628"]').on("click", function(event) { console.log('no ajax0', $(this).attr('href')); event.preventDefault(); event.stopPropagation(); // window.location.href = 'https://stackoverflow.com/?page_id=15628'; return false; }); jQuery('ul#menu-main_menu').find('a[href*="15628"]').on("click", function(event) { event.preventDefault(); event.stopPropagation(); console.log('no ajax2', $(this).attr('href')); // window.location.href = 'https://stackoverflow.com/?page_id=15628'; return false; }); jQuery('ul#menu-main_menu').on("click", 'a[href*="15628"]', function(event) { event.preventDefault(); event.stopPropagation(); console.log('no ajax3', $(this).attr('href')); // window.location.href = 'https://stackoverflow.com/?page_id=15628'; return false; });
