标签上的Onclick事件[重复]

I have an <a> tag coming back from a php file in a json format, it is as follows:

$subarray[] = '<a href="#" onclick="profile(\'' . $row['id'] . '\')" class="buttons">...</a>';

This one works fine. However, reading some material on unobtrusive JavaScript, I'd like to remove that onclick="profile(\'' . $row['id'] . '\')" and instead add an id to the tag, and then listen for the time the id is clicked. Hence, the code will be something like the following:

$subarray[] = '<a href="#" class="buttons" id="some">...</a>';

但是，当我尝试监听事件的发生时，请使用以下代码：

$("#some").click(function() {
        alert('hi');
    });

什么都没发生。如果您能告诉我如何解决问题，并告诉我最佳做法是什么，我将不胜感激。
