我有一个选择框，如下所示。我想打印出选择框中每个项目的名称和电子邮件地址，如逗号分隔值，如

Try this:

尝试这个：

$("select").each(function() {
    var options = [];
    $(this).children("option").each(function() {
        var $this = $(this);
        options.push($this.text()+ "," + $this.val());
    });
    alert(options.join("\n"));
});

This will alert you the options for each select individually.

这将提醒您单独选择每个选项。

I think is a good example to use Traversing/map:

我认为使用Traversing / map是一个很好的例子：

$('select option').map(function () {
  return $(this).text() + ',' + $(this).val();
}).get().join('\n');

Something like this:

像这样的东西：

var s = "";
$("select option").each(function()
{
   var $option = $(this);
   s += $option.text() + ", " + $option.val() + "\n";
});

alert(s);
