JavaScript method to dynamically change pictures through select_javascript skills

The example in this article describes the method of dynamically changing images through JavaScript through selection. Share it with everyone for your reference. The specific analysis is as follows:

The following JS code triggers the SetBeerIcon() function when the select list changes. The SetBeerIcon() function can dynamically modify the image according to the selected value

...
<script language="JavaScript" type="text/javascript" >
function setBeerIcon() {
 var beerIcon = document.getElementById("beerIcon");
 beerIcon.src = "images/"+getSelectValue("beer")+".jpg";
}
</script>
...
<img border="0" src="" id="brandIcon" alt="brand" />
<select name="beer" id="beer" onChange="setButton();setBeerIcon();">
<option value="--Select--">Select beer</option>
  <option value="heineken">heineken</option>
  <option value="sol">sol</option>
  <option value="amstellight">amstellight</option>
  <option value="coronalight">coronalight</option>
  <option value="coronaextra">coronaextra</option>
  <option value=""></option>
</select>
