我一直试图在数组中的其他复选框（例如费用）中总结动态勾选的复选框（例如“uniform”，“educfees”，schoolFees）的值。但似乎很难（可能是因为我禁用了一些复选框，这是必要的）。
这是html：
<p>Child's Gender:<br>
<input type="checkbox" name="gender[]" id="male" value="male" ><label>Male</label><br>
<input type="checkbox" name="gender[]" id="female" value="female" ><label>Female</label><br>
<p>Child's Class:<br>
<select required name="childClass" id="childClass">
<option value="0" >Select...</option>
<option value="prenursery">Pre Nursery</option>
<option value="nursery">Nursery</option>
<option value="reception">Reception</option>
<option value="year1">Year One</option>
<option value="year2">Year Two</option>
<option value="year3">Year Three</option>
<option value="year4">Year Four</option>
<option value="year5">Year Five</option>
<option value="year6">Year Six</option>
</select>
<p>
<h2>Fees</h2>
<p>Cost of Uniform: <br>
<input type="checkbox" name="uniform[]" id="uniform24" value="24300.00" required disabled><label>Uniform Fee N24,300</label><br>
<input type="checkbox" name="uniform[]" id="uniform26" value="26300.00" required disabled><label>Uniform Fee N26,300</label><br>

<input type="checkbox" name="fee" value="15000.00" onclick="calculate()" ><label>Club <b>(optional)</b> N15,000.00</label><br>
<!--total fee is here-->
<p><b>Total Fee:

答案 0 :(得分：1)
您必须检查disabled属性是否为true：.attr('disabled')。
你可以遍历这样的属性然后我们可以通过$("input[type='checkbox']").val();
你能从这里拿走吗？
对于纯JS，我们可以选中如下所示的复选框
document.getElementById("check1").checked = true;
或
document.getElementById("check1").checked = false;
接下来让if条件循环遍历所有选项。如果option.checked值为false，则创建变量sum，这将添加document.getElementById(whatever here).value
