jQuery动画不适用于我的导航栏

Question

I have a navigation menu on top of my page made out of list items. I want to apply jQuery code to make the list items to slide down one by one when my page loads...Can't get it work.

index.html

<div class="container">
  <ul>      
      <a href="#"><li id="goFirst">Projects</li></a>
      <a href="#"><li id="goSecond">Contact</li></a>
      <a href="#"><li id="goThird">Blog</li></a>
  </ul>
</div>

script.js

$(document).ready(function() {
    $('#goFirst').animate({top: '+=75px'}, 1000);
    $('#goSecond').delay(1000).animate({top: '+=75px'}, 1000);
    $('#goThird').delay(2000).animate({top: '+=75px'}, 1000);
});

Answer 1

Use marginTop instead of top .

 $(document).ready(function() { $('#goFirst').animate({ marginTop: '+=75px' }, 1000); $('#goSecond').delay(1000).animate({ marginTop: '+=75px' }, 1000); $('#goThird').delay(2000).animate({ marginTop: '+=75px' }, 1000); });
