JQuery:nothing is loaded into iframe : <p>I took this code from this <a href="http://jsfiddle.net/praveenscience/292wF/" rel="nofollow noreferrer">jsfiddle</a>
and it's working on that but when I tried to use it on my site it doesn't work</p>

<p>you can see my page <a href="http://www.sagisepr.com/CLEANMAPS/dropdown.html" rel="nofollow noreferrer">here</a>(or run the snippet below) it seems like nothing being loaded into iframe</p>

<p>and my short code below</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;html&gt;
&lt;head&gt;
&lt;title&gt;DROPDOWN&lt;/title&gt;
&lt;link rel="stylesheet" href="styles.css"&gt;
&lt;/head&gt;

&lt;body style="width:880px"&gt;

&lt;select id="selector"&gt;
    &lt;option value="0"&gt;select year&lt;/option&gt;
    &lt;option value="http://www.sagisepr.com/CLEANMAPS/takeback_policymap_2000.html"&gt;2000&lt;/option&gt;
	&lt;option value="http://www.sagisepr.com/CLEANMAPS/takeback_policymap_2005.html"&gt;2005&lt;/option&gt;
	&lt;option value="http://www.sagisepr.com/CLEANMAPS/takeback_policymap_2008.html"&gt;2008&lt;/option&gt;
	&lt;option value="http://www.sagisepr.com/CLEANMAPS/takeback_policymap_2010.html"&gt;2010&lt;/option&gt;
	&lt;option value="http://www.sagisepr.com/CLEANMAPS/takeback_policymap_2015.html"&gt;2015&lt;/option&gt;
   
&lt;/select&gt;
&lt;div&gt;
    &lt;iframe src="about:blank" frameborder="0" id="iframeId"&gt;&lt;/iframe&gt;
&lt;/div&gt;
&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"&gt;

$(document).ready(function(){
    $("#selector").change(function(){
        $("#iframeId").attr("src", $(this).val());
    });
});
&lt;/script&gt;

&lt;/body&gt;
&lt;/html&gt;</code></pre>
