是否可以使用复选框过滤不同的元素？

Question

我找到了这段代码，我想改进它以使用不同的元素。现在它只适用于一个 div 类，但如果我希望它与这样的东西一起使用：

<div class="list">

<li class="one category1">               //get some category from this li
<a href="link">
<img src="img"/>
<p class="name">name</p></a>
<p class="age">Age: days</p>
<span class="rating category2"></span>   //get some category from this span
<span class="status category3"></span></li>   //get some category from this span

...code repeats from <li class="one category1"> to </li> many times with different values and that the content i filter

我找到的代码：

    <ul id="filter1">
        <li>
            <input type="checkbox" name="filter1" value="dark">
            Dark</li>
        <li>
            <input type="checkbox" name="filter1" value="medium">
            Medium</li>
        <li>
            <input type="checkbox" name="filter1" value="light">
            Light</li>
    </ul>

    <ul id="filter2">
        <li>
            <input type="checkbox" name="filter2" value="sm">
            Small</li>
        <li>
            <input type="checkbox" name="filter2" value="med">
            Medium</li>
        <li>
            <input type="checkbox" name="filter2" value="lge">
            Large</li>
    </ul>

    <ul id="filter3">
        <li>
            <input type="checkbox" name="filter3" value="smooth">
            Smooth</li>
        <li>
            <input type="checkbox" name="filter3" value="riven">
            Riven</li>
        <li>
            <input type="checkbox" name="filter3" value="honed">
            Honed</li>
    </ul>

    <ul id="filter4">
        <li>
            <input type="checkbox" name="filter4" value="a">
            Up to £25</li>
        <li>
            <input type="checkbox" name="filter4" value="b">
            £25 to £45</li>
        <li>
            <input type="checkbox" name="filter4" value="c">
            £45 to £65</li>
        <li>
            <input type="checkbox" name="filter4" value="d">
            £65 to £85</li>
        <li>
            <input type="checkbox" name="filter4" value="e">
            over £85</li>
    </ul>

    <p><a class="showall" href="#" />Clear Filters</a></p>

我相信以下内容与您所追求的一致，尽管到目前为止给出的细节非常模糊

var filterArray=[];

$(function(){    
    var $items=$('#items .list'), $noRes=$('.NoResults')

   var $controls = $(':checkbox').change(function(){
        if(this.checked){
            filterArray.push(this.value)
        }else{
           var idx= $.inArray(this.value, filterArray);
            filterArray.splice( idx,1);     
        }      
        filterItems();          
    });


    $('a.showall').click(function(e){
        e.preventDefault();

        $controls.prop('checked',false);
        filterArray=[];
        filterItems();
    });

    function filterItems(){
      var results=0;
      if( filterArray.length){          
              $items.hide(); 
              var $filterItems=$items.filter( '.'+filterArray.join('.')).show()
              results=$filterItems.length;
          }else{
              $items.show();
          }
          $noRes[results || !filterArray.length ? 'hide' : 'show' ]();
    }
});

如果没有关于如何处理用户在每个类别中选择多个价格或多个项目的规则，就很难做更多。
