javascript - jQuery - 显示/隐藏搜索框

Question

我编写了一些 jQuery 来在单击 div 时滑动打开搜索框。基本上，单击它会显示一个最初隐藏的 div，并且在该 div 内部是一个搜索框和一个关闭按钮。这一切都很好。然而不起作用的是关闭按钮。我的猜测是关闭按钮没有隐藏那个 div，因为它本身在 div 中。这是我得到的，这是一个 jsfiddle .

HTML

<ul class="tert-nav">
    <li><img alt="" border="0" src="images/icon-cart.png" width="16" height="16" /></li>
    <li><img alt="" border="0" src="images/icon-tickets.png" width="16" height="16" /></li>
    <li class="searchit">
        <img alt="" border="0" class="searchicon" src="images/icon-search.png" width="16" height="16" />
        <div class="searchbox">
            <img alt="" border="0" class="closesearch" src="images/icon-close.png" width="16" height="16" />
            <input placeholder="search..." type="text" />
            <input type="submit" value="" />
        </div>
    </li>
</ul>

jQuery

$(document).ready(function() {

// Search
$('ul.tert-nav li.searchit').click(function() {
    $(this).addClass('search');
    $('.searchbox').fadeIn();
    $('ul.tert-nav li img.searchicon').hide();
});

$('ul.tert-nav li.searchit img.closesearch').click(function() {
    $('.searchbox').hide();
    $('ul.tert-nav li').removeClass('search');
});

})

CSS

ul.tert-nav {
    float: right;
    position: absolute;
    margin: 0;
    padding: 0;
    right: 0;
    top: 0;
    list-style: none;
}

ul.tert-nav li {
    float: right;
    width: 26px;
    height: 28px;
    background: #3c3c3c;
    text-align: center;
    margin-left: 2px;
    cursor: pointer;
    transition: all .2s ease;
    -o-transition: all .2s ease;
    -moz-transition: all .2s ease;
    -webkit-transition: all .2s ease;
}

ul.tert-nav li:hover {
    background: #000;
}

ul.tert-nav .search {
    width: 246px;
    text-align: left;
    cursor: default;
}

ul.tert-nav .search:hover {
    background: #3c3c3c;
}

ul.tert-nav .searchbox {
    display: none;
    width: 100%;
}

ul.tert-nav .searchbox .closesearch {
    float: left;
    margin: 6px 4px 0px 4px;
    cursor: pointer;
}

ul.tert-nav .searchbox .closesearch:hover {
    opacity: 0.8;   
}

ul.tert-nav .searchbox input[type=text] {
    float: left;
    width: 184px;
    height: 24px;
    padding: 0px 0px 0px 10px;
    margin: 2px 0px 0px 0px;
    border: none;
    background: url(images/search-bg.png) no-repeat;
    outline: none;
}

ul.tert-nav .searchbox input[type=submit] {
    float: left;
    width: 26px;
    height: 24px;
    margin: 2px 0px 0px 0px;
    padding: 0px;
    border: none;
    background: url(images/search-btn.png) no-repeat;
    outline: none;
    cursor: pointer;
}

另外，这里有一张初始状态和点击/打开状态的示例图片，让您直观地了解我正在尝试做什么。谢谢!

因为关闭按钮在 .searchit 框内，所以第一个处理程序也紧随其后被触发。在关闭处理程序期间停止点击事件的传播，它应该可以工作:

$('ul.tert-nav li.searchit img.closesearch').click(function(e) {
    e.stopPropagation();
    $('.searchbox').hide();
    $('ul.tert-nav li').removeClass('search');
});
