我有一个多行表单,每行都有一个单选按钮。我希望禁用最后一个<button>标记,直到从每一行选中单选按钮为止。
我目前有一个来自上一个问题(jQuery multi-step form: disable 'next' button until input is filled in each section)的解决方案,当您选择任何单选按钮时,该解决方案将从按钮中删除disabled属性,但如果可能的话,我希望更具体一些。
这个是可能的吗?下面是我目前正在做的工作的代码:https://codepen.io/abbasarezoo/pen/vdoMGX --正如您在任何行中点击任何收音机时所看到的那样,禁用的属性会脱落。
HTML:
<form>
<fieldset>
<div class="radio-group">
<h2>Select one answer per row</h2>
<h3>Row 1</h3>
<label for="radio-1">Radio 1</label>
<input type="radio" id="radio-2" name="radio-row-1" />
<label for="radio-2">Radio 2</label>
<input type="radio" id="radio-2" name="radio-row-2" />
<label for="radio-3">Radio 3</label>
<input type="radio" id="radio-3" name="radio-row-3" />
</div>
<div class="radio-group">
<h3>Row 2</h3>
<label for="radio-4">Radio 1</label>
<input type="radio" id="radio-4" name="radio-row-4" />
<label for="radio-5">Radio 2</label>
<input type="radio" id="radio-5" name="radio-row-5" />
<label for="radio-6">Radio 3</label>
<input type="radio" id="radio-6" name="radio-row-6" />
</div>
<button disabled>Next</button>
</fieldset>
</form>jQuery:
$('fieldset input').click(function () {
if ($('input:checked').length >= 1) {
$(this).closest('fieldset').find('button').prop("disabled", false);
}
else {
$('button').prop("disabled", true);
}

您需要为单选按钮组指定相同的名称,以便每一行只选择一个单选按钮。然后,您可以简单地将选中单选按钮的长度与单选按钮组的长度进行比较,
$('fieldset input').click(function () {
var radioLength = $('.radio-group').length;
if ($('input:checked').length == radioLength) {
$('fieldset button').prop("disabled", false);
}
else {
$('button').prop("disabled", true);
}
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<fieldset>
<div class="radio-group">
<h2>Select one answer per row</h2>
<h3>Row 1</h3>
<label for="radio-1">Radio 1</label>
<input type="radio" id="radio-2" name="radio-row-1" />
<label for="radio-2">Radio 2</label>
<input type="radio" id="radio-2" name="radio-row-1" />
<label for="radio-3">Radio 3</label>
<input type="radio" id="radio-3" name="radio-row-1" />
</div>
<div class="radio-group">
<h3>Row 2</h3>
<label for="radio-4">Radio 1</label>
<input type="radio" id="radio-4" name="radio-row-2" />
<label for="radio-5">Radio 2</label>
<input type="radio" id="radio-5" name="radio-row-2" />
<label for="radio-6">Radio 3</label>
<input type="radio" id="radio-6" name="radio-row-2" />
</div>
<button disabled>Next</button>
</fieldset>
</form>
