根据单选和复选框按钮显示/隐藏 div

Question

在这个页面中：http://www.metagame.gg/champions/我有几个过滤器可以显示或隐藏下面的图片。

我已经创建了一个脚本来根据单选按钮的选择显示/隐藏 div，但它仅在选择 5 个选项时才有效。此外，我无法弄清楚如何专门对复选框进行编程。

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 和 Tank and Melee，则显示的 div 应该只有类 .top、.tank 和 .melee

这里是 HTML

<div id="selector">

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>

这是我设法创建的 JS。我坚持认为它仅在选择每 5 个单选按钮中的一个选项时才有效。

    $('#selector input').click(function() {
        var position = $('input[name=posi]:checked').val();
        var role = $('input[name=role]:checked').val();
        var dmg = $('input[name=dmg]:checked').val();
        var powers = $('input[name=powers]:checked').val();
        var skill = $('input[name=skill]:checked').val();

        var selected = position + role + dmg + powers + skill;
        $('.item').not(selected).hide();
        $('.item' + selected).show();
    });
    $("#resetCheckboxes").click(function(){
        $("#selector input").removeAttr("checked");
        $('.item').show();
    })

我对 javascript 有点陌生，因此非常感谢任何帮助。 非常感谢您。

Answer 1

你可以使用.each()

$('#selector input').on('change',function() {
     var selected = '';
     $('input:checked').each(function(){
        selected += $(this).val();
     });
     alert(selected);
     $('.item').not($(selected)).hide();
     $('.item' + selected).show();
 });

Answer 2

我没有尝试和测试你的代码...我不得不承认。
但是作为对您的 js 的第一次快速阅读，我清楚地看到您根据它们的“checked”属性定义了 var。当没有对特定名称输入进行检查时，就会出现漏洞。结果可能是“未定义”的变量。您检查过控制台结果吗？

我相信设置默认值是个好主意！

像这样：

$('#selector input').click(function() {
    if ( $( elem ).is( ":checked" ) ){
        // Your var definition
    }else{
        // Define a default value !
    }
}

为每个人都这样做。

Answer 3

您可以检查任何值是否为undefined，然后继续使用show/hide 功能。

$('#selector input').click(function() {
  var position = $('input[name=posi]:checked').val();
  var role = $('input[name=role]:checked').val();
  var dmg = $('input[name=dmg]:checked').val();
  var powers = $('input[name=powers]:checked').val();
  var skill = $('input[name=skill]:checked').val();
  if (position == undefined || role == undefined || dmg == undefined || powers == undefined || skill == undefined) {} else {
    var selected = position + role + dmg + powers + skill;
    console.log(selected, $('.item' + selected));
    $('.item').not(selected).hide();
    $('.item' + selected).show();
  }

});
