悬停上的jquery动画边框

Question

这个功能几乎没用。

当您将鼠标悬停在导航中的不同链接上时，想法是让某种高亮显示（背景或下划线）跟随您，当您将鼠标悬停在不同的链接上时，它会找出左侧定位和宽度和动画匹配。

我需要修理什么？

• 在mouseleave或mouseout上突出显示的边框应返回活动项
• 活动项目应始终是突出显示的项目。

如果您需要更多信息，请询问 我不确定我错过了什么。

添加了unhover行为。

＆＃13;

$(function() {

  $(".app-promo-img-align:first").addClass("active");

  $('.app-promo-images').find('.app-promo-img-align').click(function(e) {

    $(this).addClass("active");
  });

  var $el, leftPos, newWidth,
    $mainNav = $(".menu");

  $mainNav.append("<div id='magic-line'></div>");
  var $magicLine = $("#magic-line");

  $magicLine
    .width($(".app-promo-img-align.active").width())
    .css("left", $(".app-promo-img-align.active a").position().left)
    .data("origLeft", $magicLine.position().left)
    .data("origWidth", $magicLine.width());

  $(".menu li a").hover(function() {
    $el = $(this);
    leftPos = $el.position().left;
    newWidth = $el.parent().width();
    $magicLine.stop().animate({
      left: leftPos,
      width: newWidth
    });

  }, function(){
  $el = $('li.active');
  console.log($el);
    leftPos = $el.position().left;
    newWidth = $el.width();
    console.log(leftPos, newWidth);
    $magicLine.stop().animate({
      left: leftPos,
      width: newWidth
    });
  }).click(function() {

Answer 2

嗯，最简单的方法就是以相同的方式将你的行移动到mouseout上的活动元素。

＆＃13;

＆＃13;

$(function() {

  $(".app-promo-img-align:first").addClass("active");

  $('.app-promo-images').find('.app-promo-img-align').click(function(e) {
    e.preventDefault;
    $(".app-promo-img-align").removeClass("active");
    $(this).addClass("active");
  });

  var $el, leftPos, newWidth,
    $mainNav = $(".menu");

  $mainNav.append("<div id='magic-line'></div>");
  var $magicLine = $("#magic-line");

  $magicLine
    .width($(".app-promo-img-align.active").width())
    .css("left", $(".app-promo-img-align.active a").position().left)
    .data("origLeft", $magicLine.position().left)
    .data("origWidth", $magicLine.width());

  $(".menu li a").hover(function() {
    $el = $(this);
    leftPos = $el.position().left;
    newWidth = $el.parent().width();
    $magicLine.stop().animate({
      left: leftPos,
      width: newWidth
    });

  }).click(function() {
    $mainNav.find('li').removeClass('active');
    $(this).parent().addClass('active');
    $magicLine.animate({
      left: $(".app-promo-img-align.active a").position().left,
      width: $(".app-promo-img-align.active").width()
    });
  }).on('mouseout', function() {
    $el = $(".app-promo-img-align.active a");
    leftPos = $el.position().left;
    newWidth = $el.parent().width();
    $magicLine.stop().animate({
      left: leftPos,
      width: newWidth
    });
  });


  $('.menu li:not(".app-promo-img-align.active")').hover(
    function() {
      $('#magic-line').addClass('hover');
    },
    function() {
      $('#magic-line').removeClass('hover');
    }
  );



});
