on the basis of your only jQuerytag :)

基于你唯一的jQuery标签:)

HTML

HTML

<select id="my-select">
<option value="1">This is text 1</option>
<option value="2">This is text 2</option>
<option value="3">This is text 3</option>
</select>

For text--

对于文字——

$(document).ready(function() {
    $("#my-select").change(function() {
        alert($('#my-select option:selected').html());
    });
});

For value--

对于价值——

$(document).ready(function() {
    $("#my-select").change(function() {
        alert($(this).val());
    });
});
