Question

我是Jquery的新手，并且对Jquery函数有一点问题。我从某处获得了代码，并希望添加一个小功能，如点击任何地方，但搜索框将隐藏搜索框。目前，当我点击img close.png时，搜索框才会隐藏:(

这是代码

<script>
$(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(e) {
    e.stopPropagation();
    $('.searchbox').hide();
    $('ul.tert-nav li').removeClass('search');
});

})
</script>

HTML代码：

<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>

CSS：

@charset "utf-8";
/* CSS Document */

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;
}

当您检查div元素时，serchbox是div的子代，这里是适合您的代码

    $(document).bind('click', function(e){
     var par = $(e.target).parent();
    if(!$('.searchbox').is(e.target))
    {
       if( typeof par != 'undefined' && par.attr('class')=='searchbox')
        return;
            $('.searchbox').hide();

    };    
   });

你可以这样做

$(document).on("click", function(e){
    if( !$(".searchbox").is(e.target) ){ 
        $(".searchbox").hide();
    }
});

Answer 2

你可以这样做：

$(document).click(function (e) {
  if($(".searchbox").is(":visible") && !$(".searchbox").is(e.target)) {
      $(".searchbox").fadeOut();
  }
});

单击除自身以外的任何位置隐藏搜索框
