我是这个环境中的新手，想请求协助我如何使用多个下拉菜单列表来处理我的简单网页。我知道这个JS是单个下拉菜单，只想得到一些关于如何获得的输入在多个下拉函数中使用它

var urlmenu = document.getElementById( 'menu1' );
 urlmenu.onchange = function() {
      window.open( this.options[ this.selectedIndex ].value );
 };

Answer 1

very easy
var urlmenu = document.getElementById( 'menu1' );
 urlmenu.onchange = function() {
      window.open( this.options[ this.selectedIndex ].value );
 };

用于菜单一

var urlmenu = document.getElementById( 'menu2' );
 urlmenu.onchange = function() {
      window.open( this.options[ this.selectedIndex ].value );
 };

用于菜单2

var urlmenu = document.getElementById( 'menu3' );
 urlmenu.onchange = function() {
      window.open( this.options[ this.selectedIndex ].value );
 };

用于菜单3

只需将menu1更改为任何不同的

Answer 2

看起来像你真正想要的是创建一个共同的功能。

试试这个：

$('select').change(function(){
    var myVal = $(this).val();
    alert(myVal);
    //open window code here
    //blah blah
});
