How to display the value of the drop-down box in jq

WBOYOriginal: 2016-09-06 08:42:54818browse

I want to write something like this
There is a drop-down box. When a value is selected, the currently selected value is displayed in a div. When switching other drop-down options, the value in the div will also change.

This is my code, but it doesn't work. What's wrong?

<code><body>
    <script src="http://keleyi.com/keleyi/pmedia/jquery-1.9.1.min.js"></script>

<select id="s">
    <option value="1">Option 1</option>
    <option value="2">Option 2</option>
    <option value="3">Option 3</option>
    <option value="4">Option 4</option>
</select>
    <script type="text/javascript">
        $('#k').on('change', function()
{
    document.write($("#s").val());
    
});
    </script>
    <div id="k"></div>
</body>value值
我想在div#k中显示当前选中的下拉选项</code>

Excuse me what’s wrong
