Javascript equivalent for scanf()
<p>I would like to ask a series of question to users in one function using </p>

<pre><code>&lt;input type="text" id="input"&gt;
</code></pre>

<p>In C, the scanf() function allows you to wait for user response and continue if the user enters a value. In JavaScript, how can I wait for user response in a function without using prompt() ?</p>
