根据选择的单选项将属性值推入两个不同的数组

Question

简而言之，如果用户选择yes对于一个单选选项，我试图从input中获得data-name属性，并将其推送到一个名为accepted_array的数组。

如果用户选择no，则存储data-name到declined_array。

下面是标记的可视化:

<div class="guest__options-group">
<input id="attending-yes-0" type="radio" name="attendance-0" value="yes" data-name="John" required />
<label for="attending-yes-0">Yes</label>
</div>
<div class="guest__options-group">
<input id="attending-no-0" type="radio" name="attendance-0" value="no" data-name="John" required />
<label for="attending-no-0">No</label>
</div>
<!-- options for Alex -->
<div class="guest__options-group">
<input id="attending-yes-1" type="radio" name="attendance-1" value="yes" data-name="Alex" required />
<label for="attending-yes-1">Yes</label>
</div>
<div class="guest__options-group">
<input id="attending-no-1" type="radio" name="attendance-1" value="no" data-name="Alex" required />
<label for="attending-no-1">No</label>
</div>

以下是我尝试过的两种方法:

第一个出路。

(function ($) {
$( ".guest__attendance-input" ).each(function(index) {
$(this).on("click", function(){
var $this = $(this);
var checkedVal = $this.val();
var accepted_array = [];
var declined_array = [];
if( checkedVal == "yes" ) {
var name = $this.data("name");
accepted_array.push(name);
} else {
declined_array.push(name);
}
console.log("accepted " + accepted_array.join(","));
console.log("declined " + accepted_array.join(","));
});
});
}) (jQuery);

这只对选定的用户执行，并将名称添加到两个数组中。

第二个出路。

(function ($) {
$( ".guest__attendance-input" ).each(function(index) {
$(this).on("click", function(){
var $this = $(this);
var data = [];
var checked = $this.is(':checked');
var name = $this.attr('data-name');

if (checked) {
if (!data[name]) {
data[name] = []
}
data[name].push($this.val())
}
console.log(data);
});
});
}) (jQuery);

只将用户添加到单个数组中。

如果都选择yes，我需要两个名字都在accepted_array中。如果有人选择yes然后选择no我需要从accepted_array中删除它们，反之亦然。

如果有人选择yes，可以使用splice和inArray从数组中删除值然后选择no反之亦然

的例子:

var accepted_array = [];
var declined_array = [];
$('.guest__options-group > input[type=radio]').on('change', function() {
var $this = $(this);
var name = $this.data("name");
var checkedVal = $this.val();
var name = $this.data("name");
if (checkedVal == "yes") {
accepted_array.push(name);
declined_array.splice($.inArray(name, declined_array), 1);
} else {
declined_array.push(name);
accepted_array.splice($.inArray(name, accepted_array), 1);
}
console.log("accepted " + accepted_array.join(","));
console.log("declined " + declined_array.join(","));
});
