JQuery PHP从选择框更改URL

Question

I have single page with div element , that changes color regarding of selected color. Selection is made using select box.

Select color from table_colors where id=($_GET["id"])

Current URL :

http://localhost/colors.php?id=1

My plan is to :

• Choose color green (id=2) from select box.
• Using JQuery , to change href id value
• Refresh page (or just a DIV) to change the color

In my situation It is very important to pass value to URL How it is done?

As others have said:

<form method="get" action=colours.php">
  <select name="id">
    <option value="2">Green</option>
  </select>
  <button type="submit">Go</button>
</form>
