I have a <select> element in HTML. This element represents a drop down list. I'm trying to understand how to iterate through the options in the <select> element via JQuery.

如何使用JQuery在<select>元素中显示每个选项的值和文本?我只想在alert()框中显示它们.

How do I use JQuery to display the value and text of each option in a <select> element? I just want to display them in an alert() box.

    alert(this.text + ' ' + this.value);
});
