Check an element existence in table rows via jQuery
<p>I have a <code>table</code> tag on my page. I'm adding dynamically a new set of rows, where some of them can contain a <code>&lt;button class="btn btn-primary"&gt;&lt;/button&gt;</code> tag. I'm wondering, how to check the information via JQuery, if that table contains any rows with that button ?</p>
