我有下表

<table>
<tr class="rows"><td>cell1</td><td>cell2</td></tr>
</table>

How can i set an alert message if i clicked on any of the column of <tr class="rows">using jquery?

如果我单击any of the column of <tr class="rows">使用 jquery，如何设置警报消息？

You can use delegate for better performance which will attach click event to root container of rows i.e table

您可以使用委托以获得更好的性能，它将单击事件附加到行的根容器，即表

$(document).ready(function(){
    $("tableSelector").delegate("tr.rows", "click", function(){
        alert("Click!");
    });
});
