Javascript bookmarklet to select drop down value?

Was hoping you guys can help me out. I cant seem to figure out how to make a bookmarklet to selecting options on a drop down menu on a webpage.

Hoping to acheive: make a bookmark on my chrome browser. When I click it on this page it will select the and select level 2 in the membership box

html of the webpage

<select name="membership" onchange="submit()">
<option value="1"> Level 1</option>
<option value="2"> Level 2</option>
<option value="3"> Level 3</option>

thanks. Really new to this.

Edit: Sorry i apologize. This is the current bookmark i tried to make

javascript:document.getElementById("membership").selectedIndex = 2; <

EDIT2 < realized probably cant use get element by id since the
<select name="membership"
is using name instead of
. Is there one that can search the name=?

EDIT 3 THANKS EVERYONE for your help here you guys are amazing and i've learned alot in the past 2 hrs wiht the different type of getelements* and queryselector. thanks sideroxylon!

This might get you started. First up you select the option you want. Then trigger the onchange event. Make sure you're passing the selected value.

document.getElementsByName('membership')[0].value = 2;

function submit(val) {
<select name="membership" onchange="submit(this.value)">
  <option value="1">Level 1</option>
  <option value="2">Level 2</option>
  <option value="3">Level 3</option>

Your bookmarklet should look something like this:

javascript:document.getElementsByName('membership')[0].value = 2;document.getElementsByName('membership')[0].onchange();
