我有一个table
,每个checkbox
的第一列(在<td>
元素中)都有一个row
。选中此项后,将显示该行中的其余列。
我已经阅读了一些有关此主题的文章,并提供了一些出色的示例,但无法完全达到我想要的目的。我已经能够使用<td>
隐藏其余的css
元素,但无法将其设置为visible
。
我了解JavaScript可以做到这一点,但是我并不精通它。非常感谢您的帮助。
table {
width: 300px;
}
table td {
min-width: 150px;
border: 1px solid;
text-align: center;
padding: 5px;
}
table td lable {
margin-right: 10px;
}
.L3,
.L4,
.L5 {
visibility: hidden
}
<form method="post" action="#">
<table>
<tr>
<th>Year</th>
<th>Thank You Letter</th>
<th>Pennant</th>
<th>Trophy</th>
<th>Medal</th>
<th>Book Voucher</th>
</tr>

最佳答案
使用jQuery:
$(document).ready(function() {
$("tr td:first-child :checkbox").change(function() {
var checkboxes = $(this).parent().siblings("td").children(":checkbox");
var containers = $(this).parent().siblings("td:not(first-child)");
if (this.checked) {
containers.css('visibility', 'visible');
checkboxes.prop("checked", true);
} else {
containers.css('visibility', 'hidden');
checkboxes.prop("checked", false);
}
});
});
table {

table td {
min-width: 150px;
border: 1px solid;
text-align: center;
padding: 5px;
}
table td lable {
margin-right: 10px;
}

仅使用JS:
var primaryCheckboxes = document.querySelectorAll("tr td:first-child input[type=checkbox]");
Array.from(primaryCheckboxes).forEach(checkbox => {
checkbox.addEventListener("click", function(event) {
var secondaryCheckboxes = this.parentElement.parentElement.querySelectorAll("input[type=checkbox]");
var checkedSatus = false,
visibilityStatus = "hidden";
if (this.checked) {
checkedSatus = true;
visibilityStatus = "visible";
}
Array.from(secondaryCheckboxes).forEach(checkbox => {
if (checkbox !== this) {
checkbox.checked = checkedSatus;
checkbox.parentElement.style.visibility = visibilityStatus;
}
});
});
});
