This can be done simply with the following to get the actual text value...

这可以通过以下简单地完成以获得实际的文本值......

var value = $("[name='MyName'] option:selected").text();

or this to get the option 'value' attribute...

或者这是为了获得选项“值”属性......

var value = $("[name='MyName']").val();

With the following html, the first will give you 'MyText', the second will give you 'MyValue'

使用以下 html,第一个会给你“MyText”,第二个会给你“MyValue”

<select name="MyName">
   <option value="MyValue" selected="selected">MyText</option>
</select>

Here is a working example

这是一个工作示例

<select id ="myCombo">
   <option value="Play selected="selected">Here</option>
   <option value="Once">Again</option>
</select>

$('#myCombo option:selected').text();

This will return you "here"

这将使您返回“此处”

$('myCombo option:selected').val();

This will return you "Play"

这将返回您“播放”
