我的表单上有一个复选框列表。当用户选择“实验室”时,我希望显示第二个复选框列表。我不希望在他们点击“实验室”复选框之前显示第二个复选框列表。
如何在Javascript或jQuery中完成此操作?

while ($tstmt->fetch()){
$d1= '<input type="checkbox" name="test[]"
value="'.$mtn.'">'.$mtn.'<br>';
echo $d1;
}

您可以使用以下内容,
此外,您可以使用$(document).ready(function() {
//initially hide all the sub lists
$(".sublists").children().each(function() {
if ($(this).attr("data-sub-list") == "true") {
$(this).hide();
}
});
// when you click the checkbox show Radiology,Radiology or ect.
$("input[name=test]").click(function() {
var list = $(this).attr("data-list");
console.log(list);
if ($(this).prop('checked')) {
$("#" + list + "").show();
} else {
$("#" + list + "").hide();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="col-xs-7">

<input type="checkbox" name="test" id="Laboratory" value="Laboratory" data-list="Laboratory-list">Laboratory

在所有情况下,你必须生成它(例如在隐藏的ul
中)并使用jQuery显示它,如$(“#mydiv”)。toggle();

您可以使用JQuery .toggle()
函数来显示/隐藏元素。
$(document).ready(function() {
$('input[type="checkbox"]').click(function() {
if ($(this).attr("value") == "lab") {
$(".labboxes").toggle();
}
});
});
.labboxes {
margin: 10px;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox">Radiology
<input type="checkbox" value="lab">Laboratory
<div class="labboxes">
<div>
<input type="checkbox" name="topic"><span>Triglyceride</span>
</div>
<div>
<input type="checkbox" name="topic"><span>VLDL</span>
</div>
<div>
<input type="checkbox" name="topic"><span>Creatinine</span>
</div>
</div>
