Jquery and native js get examples of values selected in the select drop down box

Now I have a drop-down box with id=test, how do I get the selected value?

Use javascript native methods and jquery methods, respectively

 
<select id="test" name=""> 
<option value="1">text1</option> 
<option value="2">text2</option> 
</select> 

One: javascript native methods

Var myselect= document.getelementbyid ("test");

2: get the index of the selected item: var index= myselect.selectedindex; // selectedIndex represents the index of the item you selected

3: value of selected options: myselect.options[index]. Value;

Text: myselect.options[index]. Text;

2. Jquery methods (provided that the jquery library has been loaded)

1: var options = $(" # test option: selected "); // gets the selected item

2: alert (options. Val ()); // gets the value of the selected item

3: alert (options. The text ()); // get the text of the selected item
