Answer 1

问题是，当您单击内部li时，单击和单击都发生了，您可以在事件内部使用stopPropagation来防止

Answer 2

you have to disable the bubbling

$(".child").on("click", function(event) {
    event.preventDefault(); // diasble default action
    event.stopPropagination();  // disable bubbling to parent event
    var l = $(this).parents('ul').length
    var a = 101*l;
    $(".open").css({
      "left": "-" + a + "%"
    })
  })

not tested

You can stopt the propagation with event.stopPropagation(); . I added a console.log() so that you see what is clicked.

 $(".child").on("click", function(event) { event.stopPropagation(); var l = $(this).parents('ul').length var a = 101 * l; console.log("click: " + $(this).find(">a").text()); $(".open").css({ "left": "-" + a + "%" }) }) 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="open"> <ul> <li class="child"> <a href="#">link1</a> <ul> <li class="child"> <a href="#">menu link1</a> </li> </ul> </li> </ul> </div>
