My question is whether googlebot can track pages redirected through javascript onchange function:
Example:
<select id="bla">
<option value="1">page1</option>
<option value="2">page2</option>
</select>
<script type="text/javascript">
document.getElementById("bla").onchange = function() { // code to redirect }
</script>
Now, will googlebot be redirected to page2 or page1?
According to the documentation they “may not”:
