有没有更好的方法来编写这个显示/隐藏JQuery代码？

好的，我终于按照我想要的方式工作了。

我需要它有显示/隐藏的不同按钮，并隐藏如果要求显示另一个DIV，我还需要将我的标签放在远离我的DIV标签以及添加和删除活动的类。但是，即使它有效，我知道它真的很混乱。

这是JS：

$(document).ready(function() {

    // Feature box 1

    $('#show1').click(function() {
        $('#show2,#show3,#show4,#show5,#show6').removeClass("active");
        $("#feature-2,#feature-3,#feature-4,#feature-5,#feature-6").hide();
        $("#feature-1").show();
        $(this).addClass("active");
    });

    $('#hide1').click(function() {
        $(this).parent().hide();
        $('#show1').removeClass("active");
    });

    // Feature box 2

    $('#show2').click(function() {
        $('#show1,#show3,#show4,#show5,#show6').removeClass("active");
        $("#feature-1,#feature-3,#feature-4,#feature-5,#feature-6").hide();
        $("#feature-2").show();
        $(this).addClass("active");
    });

    $('#hide2').click(function() {
        $(this).parent().hide();
        $('#show2').removeClass("active");
    });

    // Feature box 3

    $('#show3').click(function() {
        $('#show1,#show2,#show4,#show5,#show6').removeClass("active");
        $("#feature-1,#feature-2,#feature-4,#feature-5,#feature-6").hide();
        $("#feature-3").show();
        $(this).addClass("active");
    });

    $('#hide3').click(function() {
        $(this).parent().hide();
        $('#show3').removeClass("active");
    });

    // Feature box 4

    $('#show4').click(function() {
       $('#show1,#show2,#show3,#show5,#show6').removeClass("active");
        $("#feature-1,#feature-2,#feature-3,#feature-5,#feature-6").hide();
        $("#feature-4").show();
        $(this).addClass("active");
    });

    $('#hide4').click(function() {
        $(this).parent().hide();
        $('#show4').removeClass("active");
    });

    // Feature box 5

    $('#show5').click(function() {
       $('#show1,#show2,#show3,#show4,#show6').removeClass("active");
        $("#feature-1,#feature-2,#feature-3,#feature-4,#feature-6").hide();
        $("#feature-5").show();
        $(this).addClass("active");
    });

    $('#hide5').click(function() {
        $(this).parent().hide();
        $('#show5').removeClass("active");
    });

    // Feature box 6

    $('#show6').click(function() {
       $('#show1,#show2,#show3,#show4,#show5').removeClass("active");
        $("#feature-1,#feature-2,#feature-3,#feature-4,#feature-5").hide();
        $("#feature-6").show();
        $(this).addClass("active");
    });

    $('#hide6').click(function() {
        $(this).parent().hide();
        $('#show6').removeClass("active");
        });
    });

这是HTML：

<a href="#" id="show1">Show</a>
<a href="#" id="show2">Show</a>
<a href="#" id="show3">Show</a>
<a href="#" id="show4">Show</a>
<a href="#" id="show5">Show</a>
<a href="#" id="show6">Show</a>

<div id="feature-1">
    Fill this space with really interesting content 1. <a href="#" id="hide1">Hide</a>
</div>

<div id="feature-2">
    Fill this space with really interesting content 2. <a href="#" id="hide2">Hide</a>
</div>


<div id="feature-3">
    Fill this space with really interesting content 3. <a href="#" id="hide3">Hide</a>
</div>

<div id="feature-4">
    Fill this space with really interesting content 4. <a href="#" id="hide4">Hide</a>
</div>

<div id="feature-5">
    Fill this space with really interesting content 5. <a href="#" id="hide5">Hide</a>
</div>

<div id="feature-6">
    Fill this space with really interesting content 6. <a href="#" id="hide6">Hide</a>
</div>

这是CSS：

#feature-1,#feature-2,#feature-3,#feature-4,#feature-5,#feature-6 {
    height:300px;
    background-color: #99CCFF;
    padding:20px;
    margin-top:10px;
    border-bottom:5px solid #3399FF;
    display: none;
}
.active{background:#00FFFF;}

几乎总有一种更好的方式......;）

<强> JavaScript的： 

$("document").ready(function(){
    $("#links a").click(function(){
        $(".feature").hide();
        $("#features div").eq($(this).index()).show();
    });
    $("a.hide").click(function(){
        $(this).parent("div").hide();
    });
});

HTML：（我稍微改变了您的HTML结构）

<div id="links">
    <a href="#">Show</a>
    <a href="#">Show</a>
    ...
</div>

<div id="features">
    <div class="feature">
        Fill this space with really interesting content 1. <a href="#" class="hide">Hide</a>
    </div>
    <div class="feature">
        Fill this space with really interesting content 2. <a href="#" class="hide">Hide</a>
    </div>
    ...
</div>

您可以使用类而不是ID。根据您当前的标记，我缩小了您的代码，尝试以下操作：

$(document).ready(function() {

    $('a[id^=show]').click(function() {
        var which = this.id.slice(-1);
        $(this).addClass("active").siblings('a').removeClass("active");
        $("div[id^='feature']").hide();
        $("#feature-"+which).show();
    });

    $('a[id^=hide]').click(function() {
        var which = this.id.slice(-1);
        $(this).parent().hide();
        $('#show'+which).removeClass("active");
    });

});

/// javascript

function myfunction(anchor_id, feature_id){
 $('.anchors').removeClass("active");
    $(".features").hide();
    $("#"+feature_id).show();
    $("#"+anchor_id).addClass("active");
}

我已经尽量减少了你的一些JS代码，所以它会对你有所帮助
