如何从JSON哈希创建HTML选择选项？

只是这里的踢是纯Javascript的答案，您可能也不需要数组，只需一个简单的对象即可

    <select name="datas" id="datas"></select>    <script>        html = "";        obj = { "1" : "Name", "2": "Age", "3" : "Gender"        }        for(var key in obj) { html += "<option value=" + key  + ">" +obj[key] + "</option>"        }        document.getElementById("datas").innerHTML = html;    </script>
