单击时在每个tr行上切换类

Question

For some reason I can't get the class of "selected" to toggle on when each row is clicked 由于某些原因，单击每一行时无法打开“选择”类

$("tr").click(function() {
      $(this).toggleClass('selected');
};

table tr.user:hover {
    background: #007A00;
}
table tr.selected {
    background: #198719;
}

Should be a simple fix, but I can't see what I'm doing wrong. 应该是一个简单的修复程序，但是我看不到我在做什么错。

$("tr").click(function() {
      $(this).toggleClass('selected');
});

You are missing a closing bracket at the end. 您最后缺少一个右括号。
