jquery多个下拉菜单 [英] jquery multiple dropdown filter menu

问题描述

我有一个隐藏和显示的图片基于多个下拉菜单选择。我试图让2和可能更多的下拉菜单合作来完善搜索。

如果我在第一个下拉列表中选择一个项目，我想应用第二个过滤器等等，并附加任何额外的下拉列表。

我需要jQuery的一些帮助。我当前的问题是第二个过滤器从不踢，它被覆盖并重置过滤器。如果可能，我想添加一个第三个过滤器来缩小搜索范围，甚至找到我正在寻找的内容。这里是一些示例代码。

  $（'select'）。change（function（）{
 var current = $（this）.attr（'value'）; 
 
 if（current =='all'）{
 $（'＃FilterContainer'）。children（'div.all' ）.show（）; 
} 
 
 else {
 
 $（'＃FilterContainer'）。children（'div：not（。'+ current + ）'）hide（）; 
 $（'＃FilterContainer'）。children（'div。'+ current）.show（）; 
} 
 
 return false; 
}）
  

HTML

 < p>过滤器：< / p> 
< select class =filterby> 
< option value =all>< h5>显示全部< / h5>< / option> 
< option value =1>< h5> One< / h5>< / option> 
< option value =2>< h5> Two< / h5>< / option> 
< option value =3>< h5> Three< / h5>< / option> 
< / select> 
 
 
 
< p>位置：< / p> 
< select class =filterby> 
< option value =all>< h5>所有位置< / h5>< / option> 
< option value =nj>< h5> NJ< / h5>< / option> 
< option value =ny>< h5> NY< / h5>< / option> 
< option value =pa>< h5> PA< / h5>< / option> 
< / select> 
 
 
< div id =FilterContainer> 
 
< div class =all 1 nj> Test One NJ< / div> 
< div class =all 1 ny> Test One NY< / div> 
< div class =all 1 pa> Test One PA< / div> 
< div class =all 2 nj> Test Two NJ< / div> 
< div class =all 2 ny> Test Two NY< / div> 
< div class =all 2 pa>测试两个PA< / div> 
< div class =all 3 nj> Test Three NJ< / div> 
< div class =all 3 ny> Test Three NY< / div> 
< div class =all 3 pa>测试三个PA< / div> 
< div class =all 1 nj> Test One NJ< / div> 
< div class =all 1 pa> Test One PA< / div> 
< div class =all 1 pa> Test One PA< / div> 
< div class =all 2 nj> Test Two NJ< / div> 
< div class =all 2 ny> Test Two NY< / div> 
< div class =all 2 ny> Test Two NY< / div> 
  

解决方案

尝试这个 -

  $（select.filterby）。change（function（）{
 var filters = $ .map（$（select.filterby） .toArray（），function（e）{
 return $（e）.val（）; 
}）。join（。）; 
 $（div＃FilterContainer .find（div）。hide（）; 
 $（div＃FilterContainer）。find（div。+ filters）.show（）; 
}）; 
  

与 LIVE DEMO

I have pictures hiding and showing based on a multiple dropdown menu selection. I am trying to have the 2 and possible more dropdown menus working together to refine a search.

If I select an item in the first dropdown, I would like to apply the second filter and so on with any additional dropdown.

I need some help with the jquery. My current problem is the 2nd filter never kicks in. It gets overwritten and resets the filter. If possible, I would like to add a 3rd filter to narrow the search even more to find exactly what I am looking for. Here is some sample code..

$('select').change(function(){
var current = $(this).attr('value');

if(current == 'all'){
    $('#FilterContainer').children('div.all').show();
} 

else {

    $('#FilterContainer').children('div:not(.' + current + ')').hide();
$('#FilterContainer').children('div.' + current).show();
 }

  return false;
})

HTML

  <p>Filter: </p>
        <select class="filterby">
        <option value="all"><h5>Show All</h5></option>
        <option value="1"><h5>One</h5></option>
        <option value="2"><h5>Two</h5></option>
        <option value="3"><h5>Three</h5></option>
      </select>



      <p>Location: </p>
        <select class="filterby">
        <option value="all"><h5>All Locations</h5></option>
        <option value="nj"><h5>NJ</h5></option>
        <option value="ny"><h5>NY</h5></option>
        <option value="pa"><h5>PA</h5></option>
      </select>


  <div id="FilterContainer">

  <div class="all 1 nj">Test One NJ</div>
  <div class="all 1 ny">Test One NY</div>
  <div class="all 1 pa">Test One PA</div>
  <div class="all 2 nj">Test Two NJ</div>
  <div class="all 2 ny">Test Two NY</div>
  <div class="all 2 pa">Test Two PA</div>
  <div class="all 3 nj">Test Three NJ</div>
  <div class="all 3 ny">Test Three NY</div>
  <div class="all 3 pa">Test Three PA</div>
  <div class="all 1 nj">Test One NJ</div>
  <div class="all 1 pa">Test One PA</div>
  <div class="all 1 pa">Test One PA</div>
  <div class="all 2 nj">Test Two NJ</div>
  <div class="all 2 ny">Test Two NY</div>
  <div class="all 2 ny">Test Two NY</div>

解决方案

Try this -

$("select.filterby").change(function(){
    var filters = $.map($("select.filterby").toArray(), function(e){
        return $(e).val();
    }).join(".");
    $("div#FilterContainer").find("div").hide();
    $("div#FilterContainer").find("div." + filters).show();
});
