我想使用JS，但我不知道该怎么做：（
试过这个：
$("input[type=checkbox]").on("change", function() {
var $chk = $(this);
var isChecked = $chk.prop('checked');
if (isChecked) {
$chk.parent().addClass("info");
}
else {
$chk.parent().removeClass("info");
}
});
但是不起作用..
我真的需要帮助:(
非常感谢！ （对不起，如果我的英语不好，我是法国人:)）））
答案 0 :(得分：1)
您正在选择作为标签的父元素，而不是tr。使用closest查找复选框所在的tr。
$("table tbody").on("change", "input[type='checkbox']", function() {
$(this).closest("tr").toggleClass("info", this.checked);
});
答案 1 :(得分：1)
在这里，您要为.info的父label提供课程<input>
$chk.parent().addClass("info");
您需要找到确切的父<tr>来添加课程
$chk.parents('tr').addClass("info");
