我想为阿富汗和阿尔巴尼亚增加一个额外的选项值“9”。示例:当我应用过滤阿尔巴尼亚和1磅时,我得到两个结果:41美元和22美元。
HTML:
<p>Filter: </p>
<select class="filterby">
<option value="L"><h5>Afghanistan</h5></option>
<option value="E"><h5>Albania</h5></option>
</select>
<p>Location: </p>
<select class="filterby">
<option value="1"><h5>1 Pound</h5></option>
<option value="2"><h5>2 Pound</h5></option>
</select>
<div id="FilterContainer">
<div class="E 1">$41</div>
<div class="E 2">$48</div>
<div class="L 1">$28</div>
<div class="L 2">$33</div>
<div class="9 1">$22</div>
<div class="9 2">$25</div>
</div>
JAVASCRIPT:
<script type="text/javascript">//<![CDATA[
window.onload=function(){
$('#FilterContainer').hide();
$("select.filterby").change(function(){
var filters = $.map($("select.filterby").toArray(), function(e){
return $(e).val();
}).join(".");
$("div#FilterContainer").find("div").hide();
$('#FilterContainer').show();
$("div#FilterContainer").find("div." + filters).show();
});
}//]]>
</script>
答案 0 :(得分:0)
我在第一个选择的选项中添加了属性,我们可以将该属性视为您要添加的第二个值:
<p>Filter: </p>
<select class="filterby" id="allCountries">
<option value="L" dataSec="8"><h5>Afghanistan</h5></option>
<option value="E" dataSec="9"><h5>Albania</h5></option>
</select>
<p>Location: </p>
<select class="filterby">
<option value="1"><h5>1 Pound</h5></option>
<option value="2"><h5>2 Pound</h5></option>
</select>
<div id="FilterContainer">
<div class="E 1">$41</div>
<div class="E 2">$48</div>
<div class="L 1">$28</div>
<div class="L 2">$33</div>
<div class="9 1">$22</div>
<div class="9 2">$25</div>
</div>
和js:
$('#FilterContainer').hide();
$("select.filterby").change(function(){
var filters = $.map($("select.filterby").toArray(), function(e){
return $(e).val();
});
var secondVal = $("#allCountries option:selected").attr('dataSec');
$("div#FilterContainer").find("div").hide();
$('#FilterContainer').show();
$("div#FilterContainer").find("div." + filters.join('.')).show();
$("div#FilterContainer").find("div." + secondVal + "." + filters[1]).show();
});
