如何通过链接标签处理 jQuery 事件

Question

I have a link on which I have attached an attribute setnumber .

 <a class="link-container" href="page1.html" data-setnumber="100">Link to page 1</a>

I want to get this attribute as soon as the user clicks on the link, then I will use this attribute through JQuery to save some information into the database.

$(document).on('click','.link-container',function(){ 
    var el = $(".link-container").attr("data-setenumber");
    alert(el);
});

After that or at the same time, I would let the user go to the requested page (page1.html). But I never get into the JQuery file. I directly go to page1.html.
Is there a better way to do this with a link? The goal is to fill a mySQL table after the user clicks on the link, then bring the user to page1.html.

Answer 1

 $(document).on('click','.link-container', function(event){ event.preventDefault(); var el = $(".link-container").data("setnumber"); alert(el); });

Answer 2

Do not use href to go to the requested page page1.html . First get value of data-setenumber attribute and then redirect to page1.html .

<a class="link-container" href="javascript:void(0);" data-setnumber="100">Link to page 1</a>

$(document).on('click','.link-container',function(){ 
    var el = $(".link-container").attr("data-setenumber");
    alert(el);
    window.location.href = "http://localhost/page1.html";
});
