如何在jQuery中的div中获取span标签并分配文本？

I use the following ,

我使用以下，

<div id='message' style="display: none;">
  <span></span>
 <a href="#" class="close-notify">X</a>
</div>

Now i want to find the span inside the div and assign a text to it...

现在我想在div中找到跨度并为其分配文本...

function Errormessage(txt) {
    $("#message").fadeIn("slow");
    // find the span inside the div and assign a text
    $("#message a.close-notify").click(function() {
        $("#message").fadeOut("slow");
    });
}
