Are extra $(...) calls bad?
<p>If I have code that pulls down a jQuery object, and then makes some further calls on it</p>

<pre><code>$("a.postSyncLink").click(function () {
    var resultsTarget = $("span", $(link).parent().next());
    resultsTarget.html("&lt;img style='position: absolute;' src='" + waitImgUrl + "'/&gt;&lt;span&gt;Sync in progress&lt;/span&gt;");

    $.get($(this).attr("data-url"), function (returnVal) {
        resultsTarget.text(returnVal);
    });
});
</code></pre>

<p>Is it considered bad practice to subsequently (and unnecessarily) wrap that object in the jQuery function?  Does jQuery optimize superfluous calls like this?</p>

<pre><code>$("a.postSyncLink").click(function () {
    var resultsTarget = $("span", $(link).parent().next());
    $(resultsTarget).html("&lt;img style='position: absolute;' src='" + waitImgUrl + "'/&gt;&lt;span&gt;Sync in progress&lt;/span&gt;");

    $.get($(this).attr("data-url"), function (returnVal) {
        $(resultsTarget).text(returnVal);
    });
});
</code></pre>
