获取选定的文本并将其放入变量中
我有以下代码，它加载 xml 文件以填充下拉列表。我想将选定的选项文本放入变量中。我已经得到了选择的值，但没有得到文本。

$('make', xml).each(function(){

var label = $(this).text();
optionsHtml.push( "<option class='ddindent' value='"+ value +"'>"+label+"</option>");

optionsHtml = optionsHtml.join('');
select.append(optionsHtml);
select.children(":first").text("Select Make").attr("selected",true);
}
});
$('#mySelect').change(function() {
var val=$(this).val();
alert(val);
});
});

<body>
<div id="page-wrap">
<select id="mySelect">
<option>loading</option>
</select>
</div>

</html>
I have the following code which loads a xml file to populate a dropdown. I would like to put the selected options text into a variable. I already got the value of the selection but not the text.

要获取所选
的文本，您可以使用:selected和.text( ），像这样：（注意空格，它是一个子元素，所以很重要）
或者，在当前的
.change()处理程序，它看起来像这样：To get the text of the selected
<option>you could use:selectedand.text(), like this:(Note the space, it's a child so it's important)
Or, inside your current
.change()handler it would look like this:var selectedOptionValue = $('#mySelect:selected').val();var selectedOptionText = $('#mySelect:selected').html();var selectedOptionValue = $('#mySelect:selected').val();var selectedOptionText = $('#mySelect:selected').html();
