I am looking to display the pdf of one of two distributions, depending on what the user selected:
Code:
<script type="text/javascript">
function distributionChange() {
var img = document.createElement("img");
var link = 'http://en.wikipedia.org/wiki/xxx#mediaviewer/File:yyy';
switch (document.getElementById("distributions").value) {
case 'normal':
img.src = link.replace("xxx", "Normal_distribution").replace("yyy", "Normal_Distribution_PDF.svg");
break;
case 'lognormal':
img.src = link.replace("xxx", "Log-normal_distribution").replace("yyy", "Some_log-normal_distributions.svg");
break;
default:
img.src = "Distribution not specified.";
}

}
</script>
<select id='distributions' onChange='distributionChange()'>
<option name='option0' value='normal'>normal</option>
<option name='option1' value='lognormal'>lognormal</option>
</select>
<div id="distribution"></div>
