当你想要一个像绿卡这样的选项然后打开另一个选择选项有四个选择然后你选择你的选择并点击进入（提交按钮）然后我将根据链接。

- 工作---

当您选择上面的第一个选项时，如绿卡，这是正常的
我很困惑如何选择像绿卡这样的选项 - ＆gt;在有四个链接后，任何人选择然后单击按钮，位置将根据链接

请帮助如何做到这一点我不知道。

Answer 1

在按钮单击事件中，获取第一个选择框的值，然后使用该值获取相应选择框的值。然后使用该值重定向页面。

$('#Submit').click(function(e){
    e.preventDefault();
    window.location.replace($('#' + $('#DropDownList1').val()).val());
});

Answer 2

首先关闭 - 您没有关闭<form>标记。此外，我改变了你的代码，使其更具功能性（如果我理解你要做的事情）。试一试，希望它能满足您的需求。

JSFiddle

$('.toggledDropDown').parent('li').hide();  //Hide sub-dropdown menus until initial dropdown is selected

//On change of initial select
$('#DropDownList1').change(function() {
  $('.toggledDropDown').parent('li').hide();    //Hide any open sub-dropdown menus
  var id = $(this).val();   //Get value from initial dropdown for sub-dropdown ID
  $('#' + id).parent('li').show();  //Show corresponding sub-dropdown menu
});

$('#Submit').click(function() {
  var link = $('#' + $('#DropDownList1').val()).val();
  window.open(link);
});

如何使用带有值的id选择选项到另一个选择选项值dynamic
