显示3个下拉菜单中的详细信息

标签: javascript html

我在网站上有网页,我正在为大学做点什么,我在注册页面上遇到了问题。我想要一个新窗口打开我输入的详细信息。下面是我给出的代码,它显示了在一个下拉菜单中输入的数据,但生日一个有3个菜单,一个用于日,月,年。我需要帮助从这3个下拉菜单中接收代码,而不仅仅是一个。谢谢你的帮助!

function getdropdownvalue()
    {
        var range = document.form1.DOBDay.selectedIndex
        return document.form1.DOBDay.options[range].value
    }



       <body>
        <form action="" method="post" name="form1" onsubmit="checkdetails()">

在我为您提供解决方案之前,我在您的代码中注意到您缺少一些结束标记,填写代码中的下拉列表,使用表格进行格式化等。这些建议很少:

  1. 使用JS填写下拉列表。
  2. 使用一个好的编辑器来帮助您识别错过的标签。
  3. id添加到您的select / input语句中,以便更轻松地使用JS。
  4. 您是一个类似Bootstrap的框架,因此可以轻松设置页面格式,并避免使用<table>格式化页面。
  5. 这是一个简单的代码片段:

    &#13;
    &#13;
    function a() {
      var m = document.getElementById("DOBMonth");
      var y = document.getElementById("DOBYear");
      var d = document.getElementById("DOBDay");
      alert(" D:"+d.options[d.selectedIndex].value+"  M:"+m.options[m.selectedIndex].value+" Y:"+y.options[m.selectedIndex].value);
    }
    &#13;
    <select name="DOBMonth" id="DOBMonth">

只需逐个获取所需的所有元素的值(因为你说你想要数字格式的月份和日期,我得到这些元素的索引而不是值)

function getdropdownvalue()
{
      var month = document.form1.DOBMonth.selectedIndex;
      var day = document.form1.DOBDay.selectedIndex;
      var year =   document.form1.DOBYear.options[document.form1.DOBDay.selectedIndex].value;
      alert(month+' '+day+' '+year);
      return month+' '+day+' '+year;
}
