How to get the selected value on select tag using JavaScript?

Question

I have a select statement like this:

<select onchange="change_session()" name="select_path" id="select_path">
    <option name="sserver_id" id="select_path" selected value="{{ i.id }}">{{ default_server_id }}</option>
    {% for i in all_server_id %}
        <option name="server_id" id="select_path" value="{{ i.id }}">{{ i.session_name }}</option>                 
    {% endfor %}
    </select>

The first option show the default_id on the top and the second options lists all the options. User can change the option and process accordingly which is send to server using AJAX. Now I want to find out which server_id has user selected using JavaScript like this:

var serverId=document.getElementById('server_id');

How can I get the selected option?

First, you need to remove the 'name' and 'id' attributes from your <option> tags. You cannot have duplicate ids on a single page.

Next, you can use this to get the element by id:

var selected = document.getElementById('select_path').value;

use this

<select id="MySelectOption">
    <option value="1">test1</option>
    <option value="2" selected="selected">test2</option>
    <option value="3">test3</option>
 </select>

javascript

<script>
       var e = document.getElementById("MySelectOption");
         var strUser = e.options[e.selectedIndex].value;
 </script>

If you would like to get the actual text from the selected option do this:

<script>
       var e = document.getElementById("MySelectOption");
        var strUser = e.options[e.selectedIndex].text;
 </script>
