我一直在尝试检查网页上的某些单选按钮，方法是遍历所有单选按钮并尝试在每个单选按钮“组”中选择第二个值，但我对它的语法很困惑。
我在网上查找文档时，在每组单选按钮上都有相同的“名称”变量，以使每个组都易于访问，但在这个网站上情况并非如此，我被困在看似简单的解决方案中。
我一直在尝试检查每个组中的“radX_ExtendedHold”单选按钮，以禁用页面底部的“按钮页脚类”，直到用户从任何单选组中选择任何不同的值纽扣。这是它的 HTML 代码(这不是我的网站，我无法编辑 HTML 来更改名称或任何内容的值):
<div class="subsRenewEntry">
<div class="seriesOptions" data-default="Renewed">
<span>
<input id="rad0_Renewed" type="radio" name="action_f5d61c45-69fc-e711-8d62-000c2979ba39" value="Renewed" />
<label for="rad0_Renewed" >Yes, I want to renew now</label>
</span>
<span>
<input id="rad0_ExtendedHold" type="radio" name="action_f5d61c45-69fc-e711-8d62-000c2979ba39" value="ExtendedHold" />
<label for="rad0_ExtendedHold" >Not sure, keep my seat for the time being</label>
</span>
</div>
</div>
<div class="subsRenewEntry">

<div class="buttonsFooter">
<button type="submit" class="small_button_a">

</button>
</div>我尝试使用以下代码获取“subsRenewEntry”类中的所有元素:
$( ".subsRenewEntry" ).each(function( index ) {
console.log( index + ": " + $( this ).text() );
});
这似乎返回了我需要的正确组。但它只是试图检查每个组中的第二个元素。
我尝试了各种方法来尝试解决问题，如下所示:
$( "rad" + index + "_ExtendedHold").filter('[value="ExtendedHold"]').prop('checked', true);
$('.screen-RenewSubscriptions_aspx').find('option[value="ExtendedHold"]').prop('checked', true);
但它们都不起作用。
我还尝试了一种适用于单个元素的不同方法，这对我来说不太有用，因为我需要动态分配按钮，以便它可以在具有任意 X 数量的单选按钮组的任何页面上运行.
无论如何，代码如下:
$('input:radio[name="action_f5d61c45-69fc-e711-8d62-000c2979ba39"]').filter('[value="ExtendedHold"]').attr('checked', true);
但这同样只适用于其中一个按钮(显然是因为该名称仅等同于单选按钮的名称之一)。
我对 javascript/jQuery 还是很陌生，访问这些变量的语法似乎让我很困惑，因为这似乎是一个总体上非常简单的解决方案。如果有人能指出我正确的方向，我将非常感激。我不期望有人为我编写代码，只是一些关于我哪里出错以及如何改变我的想法的指示。
最佳答案
如果你想检查每个复选框的值，那么请尝试下面的 jquery 代码。只有这段代码才能帮助你做事。如果您想要不同的结果，请在此处发表评论，以便我尝试解决它们。
