Javascript 如何使用jQuery获取所有数据id输入类值，其中数据id与当前关注的字段数据id相同？

我已经输入表单html如下

<input type="text" class="form-control featurecat-item featurecat" value="" data-id="1">
<input type="text" class="form-control featurecat-label featurecat" value="" data-id="1">
<input type="checkbox" class="filled-in featurecat-isactive featurecat" data-id="1">

<input type="text" class="form-control featurecat-item featurecat" value="" data-id="2">
<input type="text" class="form-control featurecat-label featurecat" value="" data-id="2">
<input type="checkbox" class="filled-in featurecat-isactive featurecat" data-id="2">

<input type="text" class="form-control featurecat-item featurecat" value="" data-id="3">
<input type="text" class="form-control featurecat-label featurecat" value="" data-id="3">
<input type="checkbox" class="filled-in featurecat-isactive featurecat" data-id="3">

<input type="text" class="form-control featurecat-item featurecat" value="" data-id="4">
<input type="text" class="form-control featurecat-label featurecat" value="" data-id="4">
<input type="checkbox" class="filled-in featurecat-isactive featurecat" data-id="4">

如何在jQuery中使用它

要获取数据属性，请使用.data'id'或.attr'data-id' 要选择具有此数据属性的元素，请使用[data id=…]选择器 还要检查：选中您可以使用。is'：checked' $document.readyfunction{ $.featurecat.onchange粘贴键控，函数{ //......... //var current_id=当前聚焦字段数据id //获取.featurecat项、.featurecat标签、.featurecat为活动类输入值，数据id等于当前\u id //......... var ThisInput=$this； var data_id=ThisInput.data'id'； var item=$'.featurecat item[data id='+data_id+']']'.val；//.replace/，/g； var label=$'.featurecat label[data id='+data_id+']']'.val；//.replace/，/g； var isactive=$”。featurecat isactive[data id='+data_id+']'。is'：选中“？1:0； var数据=项目：+项目+|标签：+标签+| isactive：+isactive； 控制台日志数据； }; };

  $(document).ready(function(){

    $(".featurecat").on("change paste keyup", function() {

    //.........
    // var current_id = Current focused field data-id
    // Get the .featurecat-item, .featurecat-label, .featurecat-isactive class input value which data-id is equal to current_id
    //......... 

     var item = $('.featurecat-item').val().replace(/,/g, "");
     var label = $('.featurecat-label').val().replace(/,/g, "");        
     var isactive = ($(".featurecat-isactive").prop('checked') == true) ? 1 : 0;

     var data = "item:"+item+"| label:"+label+"| isactive:"+isactive;
     console.log(data);
    });

  });
