对于一个学校项目，我需要将数据从一个html表单插入到我的数据库中。问题是，我以前从未使用过nodejs、express、handlebars或javascript，而且我似乎不知道它是如何工作的，我目前在.hbs文件中有这个表单

<div class="row">
    <form action="" method="post" class="col s12">
    <div class="row">
        <div class="col s3 offset-s1">
            <label>Sensor Type</label><br>
            <label>
                <input id="combo" class="with-gap" name="sensorType" type="radio"/>
                <span>Temperature & Humidity</span>
            </label><br>
            <label>
                <input id="temp" class="with-gap" name="sensorType" type="radio"/>
                <span>Temperature</span>
            </label><br>
            <label>
                <input id="humid" class="with-gap" name="sensorType" type="radio"/>
                <span>Humidity</span>
            </label>
        </div>
    </div>
    <div class="row">
        <div class="input-field col s3 offset-s1">
            <select id="sensorForest">
                <option value="" disabled selected>Choose your forest</option>
                <optgroup label="The Netherlands">
                    <option value="streekbos">Streekbos Bovenkarspel</option>
                </optgroup>
                <optgroup label="United States of America">
                    <option value="losAngeles">Los Angeles National Forest</option>
                </optgroup>
            </select>
            <label>Forest</label>
        </div>
        <div class="input-field col s3">
            <textarea id="textarea2" class="materialize-textarea" data-length="50"></textarea>
            <label for="textarea2">Enter sensor Location</label>
        </div>
    </div>
    <div class="row">
        <div class="input-field col s6 offset-s1">
            <div class="input-field col s6">
                <input id="latitude" type="text" class="validate">
                <label for="latitude">Latitude</label>
            </div>
            <div class="input-field col s6">
                <input id="longitude" type="text" class="validate">
                <label for="longitude">Longitude</label>
            </div>
        </div>
    </div>
    <div>
        <div class="row">
            <div class="col s12 offset-s1">
                <button class="btn waves-effect waves-light" id="submit">Submit
                    <i class="material-icons right">send</i>
                </button>
            </div>
        </div>
    </div>
    </form>
</div>

我还使用下面的脚本提取了表单中字段的值，但是我不认为我可以使用它，因为我必须使用nodejs

<script>
var submit = document.getElementById("submit");

submit.onclick = function () {
    //var sensorType = document.getElementById("sensorType").value;
    var sensorForest = document.getElementById("sensorForest").value;
    var sensorLocation = document.getElementById("textarea2").value;
    var latitude = document.getElementById("latitude").value;
    var longitude = document.getElementById("longitude").value;

    console.log(sensorForest, sensorLocation, latitude, longitude);
};
</script>

有没有人知道我应该如何将数据发送到我的数据库，或者知道一个好的教程来解释我如何做？
谢谢您
