我有一个包含行数的表，在一个表中有一个单选按钮，单选按钮重复但不起作用，我也无法更改我的dropdown_list名称，所以如何解决这个问题请帮助我。
<script>
$('input[name="radio_enable"]').on('click', function() {
if ($(this).val() === 'true') {
$('#item_dropdown_list').removeProp("disabled");
}
else {
$('#item_dropdown_list').prop("disabled", "disabled");
}
});disabled
</script>
<html>
<table border="1">
<thead>
<h3 align="center">Selected Rule</h3>
<tr>
<th data-field="id" width="25"> ID </th>
<th data-field="details" width="20"> RuleName </th>
<th data-field="repeats" width="100"> Repeats </th>
</tr>
<tbody>
<c:forEach items="${List2}" var="as">
<tr>
<td> ${as.rule.id}</td>
<td> ${as.rule.ruleName}"</td>
<td><input type="radio" data-select="#item_dropdown_list1" name="radio_enable1" value="true">
<select id="item_dropdown_list1" name="item[dropdown_list]" disabled="disabled" name="ruleList[].repeats" style="width: 80px;">

</select>

我在不同的td有两个单选按钮，当我选择一个td的另一个单选按钮时应该禁用，但是它不能正常工作，
如何用jquery做到？
谢谢你！答案 0 :(得分：0)
首先，请参阅why you should use prop
*编辑*
假设你有多行，每个输入无线电指的是相对行选择，你可以这样做。
将数据属性设置为无线电，指向必须更新的选择ID：
<input type="radio" data-select="#item_dropdown_list1" name="radio_enable1" value="true"> True<br>
<input type="radio" data-select="#item_dropdown_list1" name="radio_enable1" value="false"> False<br>
select元素必须具有如下ID：
<select id="item_dropdown_list1" name="item[dropdown_list]" disabled="disabled" name="ruleList[].repeats" style="width: 80px;">
<option value="${freq.frequencyName}" />
</select>
然后在jQuery中你可以这样做：
$('input[type="radio"]').on('click', function() {
var val = $(this).val(),
selectId = $(this).data('select');
if ($(this).val() === 'true') {
$(selectId).prop("disabled", false);
}
else {
$(selectId).prop("disabled", true);
}
});

您需要对代码进行一些更改。
首先，单行 固定和重复列中的2输入广播必须具有相同的名称属性。像这样：
<td><input type="radio" name="radio_enable_0" value="fixed"></td>
<td><input type="radio" name="radio_enable_0" value="true"></td>
但是，这个名称必须为循环中的每一行更改，如下所示：
<!-- first row -->
...
<td><input type="radio" name="radio_enable_0" value="fixed"></td>
<td><input type="radio" name="radio_enable_0" value="true"></td>
...
<!-- second row -->
...
<td><input type="radio" name="radio_enable_1" value="fixed"></td>
<td><input type="radio" name="radio_enable_1" value="true"></td>
...
为此，我们需要在c:forEach循环中使用 index variable ：<input type="radio" name="radio_enable_${as.index}">。
请尝试使用此代码进行循环：
<c:forEach items="${List2}" var="as">
<tr>
<td> ${as.rule.id}</td>
<td> ${as.rule.ruleName}"</td>
<td> <input type="radio" name="radio_enable_${as.index}" value="fixed"> </td>
<td>
<input type="radio" name="radio_enable_${as.index}" value="true">
<select id="item_dropdown_list1" name="item[dropdown_list]" disabled name="ruleList[].repeats" style="width: 80px;">
<c:forEach items="${listfrequency}" var="freq">
<option value="${freq.frequencyName}" />
<c:out value="${freq.frequencyName}" />
</c:forEach>
</select>
</td>
</tr>
</c:forEach>
然后在jquery中你可以做到：
$('input[type="radio"]').on('click', function() {
var val = $(this).val(),
selectId = $(this).closest('tr').find('select').first();
if ($(this).val() === 'true') {
$(selectId).prop("disabled", false);
}
else {
$(selectId).prop("disabled", true);
}
});
这是最后的JSFIDDLE
