javascript - 仅根据单选按钮和复选框按钮显示/隐藏 div

Question

在此页面中:http://www.metagame.gg/champions/我有几个过滤器来显示或隐藏下面的图片。

我已经创建了一个脚本来根据第一个单选按钮(位置)的选择来显示/隐藏 div。但我无法弄清楚如何专门对其余选择器(单选按钮和复选框)进行编程。

选择不同字段的结果应通过AND条件关联。

例如:如果我选择 Top、Tank 和 Melee，则显示的 div 应该只是类为 .top、.tank 和 .melee 的 div

这是 HTML

<div id="selector">

<div id="resetCheckboxesDiv">
    <button id="resetCheckboxes">Reset</button>
</div>
</div>

这就是图片 HTML 的外观。注意调节过滤器的不同类:

<div class="item  Melee Crowd-Control Engage  Counter-Engage Jungle-Clear Burst  Scape  Splitpush Sustain    Normal egame  Fighter    Tank Hybrid top jungle  ">
    <a href="aatrox">
        <img class="champavatar2" src="/icon/champions/aatrox.png" alt="">
        <div class="textavatar">Aatrox</div> 
    </a>
</div>

<div class="item Ranged  Crowd-Control Engage  Counter-Engage  Burst Poke Scape Siege  Sustain Teamfight Wave-Clear  High mgame Assassin   Mage   AP   mid ">
    <a href="ahri">
        <img class="champavatar2" src="/icon/champions/ahri.png" alt="">
        <div class="textavatar">Ahri</div> 
    </a>
</div>

<div class="item  Melee      Burst  Scape  Splitpush Sustain    Normal lgame Assassin Fighter     Hybrid top  mid ">
    <a href="akali">
        <img class="champavatar2" src="/icon/champions/akali.png" alt="">
        <div class="textavatar">Akali</div> 
    </a>
</div>

<div class="item  Melee Crowd-Control Engage Disengage Counter-Engage    Scape   Sustain Teamfight  Peel High lgame  Fighter   Support Tank AP    bot">
    <a href="alistar">
        <img class="champavatar2" src="/icon/champions/alistar.png" alt="">
        <div class="textavatar">Alistar</div> 
    </a>
</div>

这是我为第一个单选选择器创建的 JS:

$('input[name=posi]').click(function() {
    if( $('input[name=posi]:checked').val() == '.top' ) {
        $('.top').show(); 
        $('.jungle').hide();   
        $('.mid').hide();   
        $('.bot').hide();   
    }
    else if ( $('input[name=posi]:checked').val() == '.jungle' ) {
        $('.top').hide();   
        $('.jungle').show();   
        $('.mid').hide();   
        $('.bot').hide();   
    }
    else if ( $('input[name=posi]:checked').val() == '.mid' ) {
        $('.top').hide();  
        $('.jungle').hide();   
        $('.mid').show();   
        $('.bot').hide();   
    }
    else if ( $('input[name=posi]:checked').val() == '.bot' ) {
        $('.top').hide();   
        $('.jungle').hide();   
        $('.mid').hide();   
        $('.bot').show();  
    }
});

我对 javascript 有点陌生，所以非常感谢任何帮助。预先非常感谢您。

对于您的情况，我实际上建议使用 .not()功能。

因此，您想要做的是创建所有选定 radio 及其值的列表，并用 . 字符分隔 - multiple class selectors 的表示法。 .

因此，对于您的示例，如果我选择 Top、Tank 和 Melee，则显示的 div 应该仅包含类 .top、.tank 和 .melee，您的选择器字符串将为 “.top.tank.melee”。

使用该字符串，您可以显示匹配的字符串并隐藏不匹配的字符串:

var selected = ...;               // <-- for example, ".top.tank.melee"
$('.item').not(selected).hide();  // hide items not matching your classes
$('.item' + selected).show();     // show items matching your classes
