如何显示或基于复选框选择

Question

我试图根据复选框选中此选项显示的值，并取消

例如，如果显示所有数学复选框选择隐藏容器内div的，我想显示所有针对数学选择

类似地，如果显示所有物理复选框被选中的包面板，我想显示所有这Physiscs选择

包面板

我已经尝试过这种方式

$(document).on('change', '.filtermaths', function() { 
$(".pack-panel").each(function() { 
    var visible = $(this).find('.mathscheckbox').prop('checked') 
    $(this).toggle(visible); 
    }); 
    }); 


$(document).on('change', '.filterphysics', function() { 
$(".pack-panel").each(function() { 
    var visible = $(this).find('.physicscheckbox').prop('checked') 
    $(this).toggle(visible); 
    }); 
    }); 

    $(document).on('change', '.filterchemistry', function() { 
$(".pack-panel").each(function() { 
    var visible = $(this).find('.chemistrycheckbox').prop('checked') 
    $(this).toggle(visible); 
    }); 
    }); 

但预期

这是不工作这是我的小提琴

你可以尝试这样的事情。

$(document).on("change", ".actions", function(event) { 
 
    if ($("input[name='includeAll']:checked").val() === "OR") { 
 
    if ($("input:checked", $(".actions")).length === 0) { 
 
     $(".pack-panel").addClass("visible").removeClass("hidden"); 
 
    } else { 
 
     $(".pack-panel").addClass("hidden"); 
 
    } 
 

 
    $("input:checked", $(".actions")).each(function() { 
 
     var $target = $(this); 
 
     var isChecked = $target.prop("checked"); 
 
     var value = $target.data("course-flag"); 
 

 
     if (isChecked) { 
 
     $("." + value + "-checkbox:checked").closest(".pack-panel").addClass("visible").removeClass("hidden"); 
 
     } 
 
    }); 
 
    } else { 
 

 
    var selectedCourses = []; 
 

 
    $("input:checked", $(".actions")).each(function() { 
 
     selectedCourses.push($(this).data("course-flag")); 
 
    }); 
 

 
    selectAll(selectedCourses); 
 
    } 
 

 

 
}); 
 

 
function selectAll(courses) { 
 

 
    $(".pack-panel").each(function() { 
 
    var $panel = $(this); 
 
    var allSelected = true; 
 
    courses.forEach(function(course) { 
 

 
     if ($panel.find("." + course + "-checkbox:checked").length === 0) { 
 
     allSelected = false; 
 
     } 
 
    }); 
 

 
    if (allSelected) { 
 
     $panel.addClass("visible").removeClass("hidden"); 
 
    } else { 
 
     $panel.removeClass("visible").addClass("hidden"); 
 
    } 
 
    }); 
 
}

.visible { 
 
    display: block; 
 
} 
 
.hidden { 
 
    display: none; 
 
}

我修改的标记位有从复选框选择外观UPS在顶部包板里面的人。

修改了代码以适应OR和AND条件。这应该可以解决你的问题。

Answer 2

var fields = ['maths', 'physics', 'chemistry']; 
var visible = {}; 

$('.actions input').on('change', function(){ 
    var atLeastOne = false; 
    for(var field of fields){ 
     visible[field] = false; 
     if($('.filter' + field).prop('checked')){ 
      visible[field] = true; 
      atLeastOne = true; 
     } 
    } 

    if(!atLeastOne){ 
     $(".pack-panel").show(); 
    }else{ 
     $(".pack-panel").hide(); 
     for(var field of fields){ 
      if(!visible[field]){ continue; } 
      $(".pack-panel").each(function() { 
       if($(this).is(':visible')) { return; } 
       if($(this).find('.'+field+'checkbox').prop('checked')){ 
        $(this).show(); 
        return; 
       } 
      }); 
     } 
    } 
}); 

Answer 3

试试这个最短的代码

$('.actions input').on('change', function() { 
    if ($('.actions input:checked').length <= 0) 
     $(".pack-panel").show(); 
    else { 
     $(".pack-panel").show(); 
     $('.actions input:checked').each(function() { 
      var cclass = $(this).attr('class').split('filter')[1] + "checkbox";      
      $('.' + cclass).each(function() {        
       if(!$(this).prop('checked')){ 
        $(this).parents('.pack-panel').hide(); 
       } 
      }); 
     }); 
    } 
});
