如何使用JQuery通过复选框过滤HTML5数据属性元素

Question

在我的列表包装器中，每个产品都有多个数据属性，例如data-baths="3"，data-beds="4"，data-halfbath="12"，data-garages="2"，data-stories="2"，data-price="2" ，data-sqft="2567"。

我的复选框的类别与data-category="value"相对应，此处值可能为baths/ beds/ halfbath/ garages/ stories/ price/ sqft

<input type=’checkbox’ class=’filter’ data-filter=’baths’ value=’1’> 1 Bathroom
<input type=’checkbox’ class=’filter’ data-filter=’beds’ value=’2’> 2 Bedrooms

因此，当用户选择复选框时，我只需要根据类别显示产品。

问题是，如果我选择多个类别（复选框值），则会缺少某些条件并显示无条件数据。

   $(".filter").change(function(){
    var beds=[],baths=[],halfbaths=[],garages=[],stories=[];    
$('.filter').each(function(){
        if($(this).is(':checked')){
            currentValue=$(this).val();     

            if($(this).attr('data-filter')==='beds'){                   
                if($.inArray(currentValue, beds) == -1){beds.push(currentValue);}   
            }
            if($(this).attr('data-filter')==='baths'){
                if($.inArray(currentValue, baths) == -1){baths.push(currentValue);} 
            }
            if($(this).attr('data-filter')==='halfbath'){

            }
        }
    });

    var bedsselector=[], bathsselector=[], halfbathssselector=[], garagesselector=[], storiessselector=[];

        });

Answer 1

我得到了解决方案，我正在回答我自己的问题，因为这个逻辑可能对某人有帮助。

使用功能齐全的代码更新了JSFiddle。

使用简单代码 JSFiddle

的另一种解决方案

这是JQuery：

jQuery(document).ready(function($){
$(".filter").change(function(){
    filterData();
});

clearfilter=function(){
    $('.filter').attr('checked',false);
    $(".listing-wrap").show("slow");
}

filterData=function(){
    var beds=[],baths=[],halfbaths=[],garages=[],stories=[];    
    $('.filter').each(function(){
        if($(this).is(':checked')){
            currentValue=$(this).val();     

            if($(this).attr('data-filter')==='beds'){                   
                if($.inArray(currentValue, beds) == -1){beds.push(currentValue);}   
            }
            if($(this).attr('data-filter')==='baths'){
                if($.inArray(currentValue, baths) == -1){baths.push(currentValue);} 
            }
            if($(this).attr('data-filter')==='halfbath'){
                if($.inArray(currentValue, halfbaths) == -1){halfbaths.push(currentValue);} 
            }
            if($(this).attr('data-filter')==='garages'){
                if($.inArray(currentValue, garages) == -1){garages.push(currentValue);} 
            }
            if($(this).attr('data-filter')==='stories'){
                if($.inArray(currentValue, stories) == -1){stories.push(currentValue);} 
            }
        }
        else{
            currentValue=$(this).val();
            if($(this).attr('data-filter')=='beds'){                    
                beds = $.grep(beds, function(b) {return b != currentValue;});                                       
            }
            if($(this).attr('data-filter')=='baths'){
                baths=$.grep(baths, function(b) {return b != currentValue;});                   
            }
            if($(this).attr('data-filter')=='halfbath'){
                halfbaths=$.grep(halfbaths, function(b) {return b != currentValue;});
            }
            if($(this).attr('data-filter')=='garages'){
                garages=$.grep(garages, function(b) {return b != currentValue;});
            }
            if($(this).attr('data-filter')=='stories'){
                stories=$.grep(stories, function(b) {return b != currentValue;});
            }
        }
    });

console.log("Beds:"+beds);
console.log("Baths:"+baths);
console.log("Halfbaths:"+halfbaths);
console.log("Garages:"+garages);
console.log("Stories:"+stories);
console.log("-----------------------");

    $('.listing-wrap').hide();
    $('.listing-wrap').each(function(){
        var this_beds=$(this).attr('data-beds');
        var this_baths=$(this).attr('data-baths');
        var this_halfbaths=$(this).attr('data-halfbath');
        var this_garages=$(this).attr('data-garages');
        var this_stories=$(this).attr('data-stories');

        //console.log(baths.length);
        console.log($.inArray(this_beds,beds));

        var isbeds=beds.length===0?true:($.inArray(this_beds,beds)>=0);
        var isbaths=baths.length===0?true:($.inArray(this_baths,baths)>=0);
        var ishalfbaths=halfbaths.length===0?true:($.inArray(this_halfbaths,halfbaths)>=0);
        var isgarages=garages.length===0?true:($.inArray(this_garages,garages)>=0);
        var isstories=stories.length===0?true:($.inArray(this_stories,stories)>=0);
        console.log("Beds:"+isbeds+",Baths:"+isbaths+",Halfbaths:"+ishalfbaths+",Garages:"+isgarages+",Stories:"+isstories);
        console.log("Beds("+this_beds+"):"+isbeds+",Baths("+this_baths+"):"+isbaths+",Halfbaths("+this_halfbaths+"):"+ishalfbaths+",Garages("+this_garages+"):"+isgarages+",Stories("+this_stories+"):"+isstories);
        var isdisplay=(isbeds&&isbaths&&ishalfbaths&&isgarages&&isstories);
        console.log("Release="+isdisplay);
        console.log("-----");
        if((isdisplay)){
            $(this).show("slow");
            }

        //else{
        //  $(this).hide("slow");
        //}
    });

}
});

这是另一个简单代码的解决方案：

$('.filter').change(function() {
var beds = $('[data-filter="beds"]:checked').map(function() {
return '[data-beds="' + $(this).val() + '"]';
}).get().join(',') || '*';

var baths = $('[data-filter="baths"]:checked').map(function() {
return '[data-baths="' + $(this).val() + '"]';
}).get().join(',') || '*';

var halfbaths = $('[data-filter="halfbaths"]:checked').map(function() {
return '[data-halfbaths="' + $(this).val() + '"]';
}).get().join(',') || '*';

var garages = $('[data-filter="garages"]:checked').map(function() {
return '[data-garages="' + $(this).val() + '"]';
}).get().join(',') || '*';

var stories = $('[data-filter="stories"]:checked').map(function() {
return '[data-stories="' + $(this).val() + '"]';
}).get().join(',') || '*';

console.log(beds + '|' + baths + '|' + halfbaths + '|' + garages + '|' + stories);

$('.listing-wrap').hide().filter(beds).filter(baths).filter(halfbaths).filter(garages).filter(stories).show('slow');

});
