javascript - JQuery - how to select dropdown item based on value

Question

I want set a dropdown(select) to be change based on the value of the entries.

I have

<select id="mySelect">
  <option value="ps">Please Select</option>
  <option value="ab">Fred</option>
  <option value="fg">George</option>
  <option value="ac">Dave</option>
</select>

And I know that I want to change the dropdown so that the option with the value of "fg" is selected. How can I do this with JQuery?

Answer 1

You should use

$('#dropdownid').val('selectedvalue');

Here's an example:

$('#dropdownid').val('selectedvalue');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id='dropdownid'>
    <option value=''>- Please choose -</option>
    <option value='1'>1</option>
    <option value='2'>2</option>
    <option value='selectedvalue'>There we go!</option>
    <option value='3'>3</option>
    <option value='4'>4</option>
    <option value='5'>5</option>
</select>
