jQuery懸停淡出p標簽並淡入另一個

Question

所以我在使它起作用方面遇到問題。 我有3個ID為＃mod1，＃mod2，＃mod3的模塊。 當您將鼠標懸停在這些標簽上時，我希望它們淡出可見的P標簽，然后淡入另一個標簽。

<ul id="homeModules">
    <li id="mod1"><a href="/portfolio/">VIEW OUR GALLERY</a></li>
    <li id="mod2"><a href="/about/">MEET SARAH</a></li>
    <li id="mod3"><a href="/become-a-client/">BECOME A CLIENT</a></li>
</ul>

<p class="homeTags" id="homeTag1">Lorem ipsum dolor sit amet.</p>               
<p class="homeTags" id="homeTag2">The Google Fonts API will.</p>                
<p class="homeTags" id="homeTag3">Check out more advanced techniques.</p>

#homeTag2, #homeTag3 {
    display: none;
}

$('#mod1').hover(function(){
    $('#homeTag2,#homeTag3').fadeOut(250);
    setTimeout(function(){
        $('#homeTag1').fadeIn(250);
    }, 500);
});

$('#mod2').hover(function(){
    $('#homeTag1,#homeTag3').fadeOut(250);
    setTimeout(function(){
        $('#homeTag2').fadeIn(250);
    }, 500);
});

$('#mod3').hover(function(){
    $('#homeTag1,#homeTag2').fadeOut(250);
    setTimeout(function(){
        $('#homeTag3').fadeIn(250);
    }, 500);
});

您太復雜了，可以改用這種方法：

HTML-從li的ID中刪除了ID

<ul id="homeModules">
    <li data-target="#homeTag1"><a href="/portfolio/">VIEW OUR GALLERY</a></li>
    <li data-target="#homeTag2"><a href="/about/">MEET SARAH</a></li>
    <li data-target="#homeTag3"><a href="/become-a-client/">BECOME A CLIENT</a></li>
</ul>

JS

var $homeTags = $('.homeTags');
$homeTags.filter(':first').show(); //Show the first one
$('#homeModules > li').hover(function(){
    var $target = $($(this).data('target')); //Get the target reading from data attribute of the hovered li
    $target.stop(true, true).fadeIn(250, function(){ //fadeIn the target and on completion of this
        $homeTags.filter(':visible').not($target).fadeOut(250); //fadeOut the others
    })
});

您也可以利用當前HTML的索引和索引（而不使用任何ID或數據目標）來進行這種方式，但是之前的更為明確。

$('.homeTags:first').show();
$('#homeModules > li').hover(function(){
    var $target = $('.homeTags').eq($(this).index())
    $target.fadeIn(250, function(){
        $('.homeTags:visible').not($target).fadeOut(250);
    });
});

的HTML

<ul id="homeModules">
  <li id="mod1"><a href="/portfolio/">VIEW OUR GALLERY</a></li>
  <li id="mod2"><a href="/about/">MEET SARAH</a></li>
  <li id="mod3"><a href="/become-a-client/">BECOME A CLIENT</a></li>
</ul>
<div class="homeTags" id="homeTag1">
  <p>Lorem ipsum dolor sit amet.</p>
</div>
<div class="homeTags" id="homeTag2">
  <p>The Google Fonts API will.</p>
</div>
<div class="homeTags" id="homeTag3">
  <p>Check out more advanced techniques.</p>
</div>

的CSS

#homeTag2, #homeTag3 {
    display: none;
}

JQUERY

$("#homeModules li").on("mouseenter", function () {
  var whichLink = $(this).attr("id").slice(-1);

  if ($("#homeTag" + whichLink).css("display") == "block") {
    return false;
  } else {
    $(".homeTags").hide();
    $("#homeTag" + whichLink).show();
  }
});
