Question

我正在尝试学习如何创建幻灯片菜单。到目前为止，我有一些基本的HTML和CSS。但是，我不确定编写jQuery的最佳方法。目前，它滑出但不会滑回。或者我可以使用CSS Transition吗？

<div class="side-menu">
   MENU
</div>

<div class="page">

    <a href="#" id="slideMenu"><i class="fa fa-bars"></i></a>

    <p>The Hon. Francis Gillette, in a speech in Hartford, Conn., in 1871, said that there was "in Connecticut, on an average, one liquor shop to every forty voters, and three to every Christian church. In this city, as stated in the _Hartford Times_, recently, we have five hundred liquor shops, and one million eight hundred and twenty-five thousand dollars were, last year, paid for intoxicating drinks. A cry, an appeal, came to me from the city, a few days since, after this wise: 'Our young men are going to destruction, and we want your influence, counsel, and prayers, to help save them.'"</p>

</div>

我的CSS：

div.side-menu {
    width:260px;
    height:400px;
    background:#202020;
    position:absolute;
    left:-260px;
    top:0px;
}

div.page {
    width:100%; 
    height:100%;
    position:relative;
    top:0;
    left:0px;
    padding:4%;
    padding-top:100px;
    background:#f4f4f4;
}


div.page a {
    display:block;
    width:50px;
    height:50px;
    -o-border-radius: 100%; 
    -webkit-border-radius: 100%; 
    -moz-border-radius: 100%; 
    border-radius: 100%;    
    background:#666;
    position:absolute;
    top:20px;
    left:4%;
    font-size:24px;
    text-align:center;
    text-decoration:none;
    padding-top:7px;
    color:#fff;
    outline:none;   
 }

p {
    color:#555; 
    font-size:18px;
    font-weight:normal;
}

我的jQuery：

    <script>
    $(document).ready(function() {

        $("a").click(function() {
        $(".page").animate({"left": "260px"},"fast");
        });

    });
    </script>

Answer 1

$（document）.ready（function（）{

    $("a").click(function() {
        if($(".page").css("left") == "0px"){
            $(".page").animate({"left": "260px"},"fast");
        }
        else{
            $(".page").animate({"left": "0px"},"fast");
        }
    });

});

Answer 2

使这样的调用更快，将整数处理为整数而不是字符串...
你也可以替换＆＃34; fast＆＃34;因为正常时间是400毫秒而200毫秒是＆＃34;快速＆＃34;

$(document).ready(function() {

    $("a").click(function() {
        if(parseInt($(".page").css("left")) == 0){
            $(".page").animate({left: 260},200);
        }
        else{
            $(".page").animate({left: 0},200);
        }
    });

});

这是简单的jQuery。当您单击导航切换链接时，它会将css类添加到页面和导航菜单中以将它们都滑动到左侧。这允许您使用相同的切换按钮来打开和关闭导航。

我还投入了一些CSS3过渡来平滑它。

您也可以在不使用jquery或javascript的情况下小心使用复选框和标签来实现此目的。
