Replace the js part with the following code, and the html remains unchanged! I didn't test it. If you have any questions, you can leave a message in Baidu hi or space. good luck!
<Script src = "introduce jquery core package" type = "text/javascript"> </script>
<Script type = "text/javascript">
$ (Function (){
$ ("# Fruit"). change (function (){
Var index = $ (this). selectedIndex;
Var len = $ (this). length;
$ ("# Show"). html ("the index number of the selected option is:" + index + "<br/> the number of options in the drop-down list is:" + len );
});
});
</Script>
