[jQuery] $("a") is not a function error

[jQuery] $("a") is not a function error


Hi everyone,
I use jquery 1.2.6. I'd like to get some attributes from a tag, but i
get some errors. Here's the jquery script:
$(document).ready(function() {
    alert($("a").href());
    alert($("a").text());
    alert($("a").title());
});
And the html is here:
<a href="the href" class="myclass" title="the title">testing</a>
The script only works for $(''a").text(), and the others show error.
Can anyone help me, why is it happen?Thanks a lot before..
