我已经找到了一个脚本，做我需要的(下拉菜单)，但我希望它能把用户带到一个外部/内部网址根据他的选择从下拉菜单，例如，如果他选择美国，然后纽约，他们去url#1，如果选择美国和新泽西去url#2，这就是我想要的

脚本：

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <script type="text/javascript">
        var citiesByState = {
            USA: ["NY","NJ"],
            Singapore: ["taas","naas"]
        }
        function makeSubmenu(value) {
            if(value.length==0) document.getElementById("citySelect").innerHTML = "<option></option>";
            else {
                var citiesOptions = "";
                for(cityId in citiesByState[value]) {
                    citiesOptions+="<option>"+citiesByState[value][cityId]+"</option>";
                }
                document.getElementById("citySelect").innerHTML = citiesOptions;
            }
        }
        function displaySelected() {
            var country = document.getElementById("countrySelect").value;
            var city = document.getElementById("citySelect").value;
            alert(country+"\n"+city);
        }
        function resetSelection() {
            document.getElementById("countrySelect").selectedIndex = 0;
            document.getElementById("citySelect").selectedIndex = 0;
        }
    </script>
</head>
<body onload="resetSelection()">
    <select id="countrySelect" size="1" onchange="makeSubmenu(this.value)">
        <option></option>
        <option>USA</option>
        <option>Singapore</option>
    </select>
    <select id="citySelect" size="1">
