HTML select options from json local file
Question
On my HTML page, I want to have two selections, one for picking nationality and another for picking month booking, but there are too many options for the first selection. I managed to get a json file with all the nationalities (looks like this [{"Code":167,"Nationality":" Russia "},{"Code":98,"Nationality":" Ireland "},{"Code":14,"Nationality":" Australia "}, ...) and now I need a simple way to replace my selection options by this. The HTML body is this:
<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">
<option value="{{nationality}}" >Nationality</option>
<option value="80">Portuguese</option>
<option value="60">English</option>
<option value="55">Spanish</option>
<option value="65">Chinese</option>
<option value="30">French</option>
</select>
</div>
<div>
<select id="selector" name="month">
<option value="{{month}}" >Booking Month</option>
<option value="01">January</option>
<option value="02">February</option>
<option value="03">March</option>
<option value="04">April</option>
<option value="05">May</option>
<option value="06">June</option>
<option value="07">July</option>
<option value="08">August</option>
<option value="09">September</option>
<option value="10">October</option>
<option value="11">November</option>
<option value="12">December</option>
</select>
<input type="submit" value="Get Hotels">
</div>
<div>
<select id="locality-dropdown" name="locality" onload="placeNationalities()"></select>
</div>
</div>
<div id="all">
<div id="mapid" style="width: 1200px; height: 600px;"></div>
<div id="filters">
<label for="fname">Number of Hotels</label>
<input type="text" name="numberHotels" value={{numberHotels}} size="5">
<label for="lname">MinAvg Rating</label>
<input type="text" name="minAvgRat" value={{minAvgRat}} size="5">

Solved with json content on html! Solution (with json reduced):
<body>
...
<div>
<select id="selectorr" name="nationality">
</select>
<script>
html = "";
obj = [{"Code":167,"Nationality":" Russia "},{"Code":98,"Nationality":" Ireland "}]
for (i=0; i<obj.length; i++) {
html += "<option value=" + obj[i].Code + ">" + obj[i].Nationality + "</option>"
}
document.getElementById("selectorr").innerHTML = html;
</script>
</div>
