Question

在我的HTML页面上，我希望有两个选项，一个用于选择国籍，另一个用于选择月份预订，但是第一个选择的选项太多了。我设法获得了一个包含所有国籍的json文件（看起来像这样 [{“代码”：167，“国籍”：“俄罗斯”}，{“代码”：98，“国籍”：“爱尔兰”} ，{“代码”：14，“国籍”：“澳大利亚”}， ...）现在我需要一种简单的方法来替换我的选择选项。 HTML正文如下：

<body onload="initialize()">
    <h1>Hotel Recommendations</h1>
    <h3>The Best Hotels in Europe</h3>

    <div id="currentText">We recommend the best hotels for you, based on your nationality and month of booking. 
        Do you want to give it a try?</div>
    <p></p>

    <form action = "/p/5433/newhotels" method ="POST">
        {% if error_message %}
          <div id="error"><p>{{error_message}}</p></div>
        {% endif %}

        <div id="floating-panel">
            <div>
                <select id="selector" name="nationality">

解决了html上的json内容！解决方案（减少了json）：

<body>
