$未在jsfiddle中定义 [英] $ is not defined in jsfiddle

问题描述

假设我有以下html:

Suppose I have the following html:

<div id="test1">hi</div>
<a href="#" onclick="showDiv()">click here</a>

和javascript:

and the javascript:

function showDiv() {
    $("#test1").hide();
}

当我在jsfiddle上尝试时，它返回:

When I try it on jsfiddle, it returns:

$未定义

$ is not defined

我错过了jsFiddle中的某些设置吗?

Did I miss some setting in jsFiddle?

谢谢.
