Question

Here is the HTML code

<select id="language">
    <option value="en">english</option>
    <option value="fr">french</option>
    <option value="gr">german</option>
</select>






<div id="related_en_content">
    english text
</div>

<div id="related_fr_content">
    french text
</div>

<div id="related_gr_content">
    german text
</div>

Every div related to one of the options in the select, I want replace div when changing the select option.

Here’s what I’ve tried:

$(document).ready(
    function() {
        $("#language").change(
            function() {
                $("#" + this.value).show().siblings().hide();
            });
        $("#language").change();
    }
