У меня есть .js, который заполняет 2 <div> данными о долготе и широте и работает отлично. Но я хочу взять эти данные и заполнить ими форму, чтобы я мог записать ее в свою базу данных, когда они нажмут кнопку отправки. Мне все равно, если форма скрыта или видна мне просто нужно, когда страница загружается и скрипт показывает данные, которые она также автоматически помещает в форму. Любая помощь очень ценится. Спасибо.
js называется main.js, который находится ниже, и код для заполнения
данные на странице:
<section>
<ul>
<dl>
<dt>Latitude:</dt>
<dd id="latitude">Please...</dd>
</dl>
<dl>
<dt>Longitude:</dt>
<dd id="longitude">Wait...</dd>
</dl>
<dl>
<dt>Accuracy:</dt>
<dd id="accuracy">While...</dd>
</dl>
<dl>
<dt>Timestamp:</dt><dd id="timestamp">Calculating...</dd>
</dl>
</ul>
</section>
<!--Now and this is my issue I need the <dd id="latitude"> and <dd id="longitude"> some how in
a form to get in a SQL database -->
<ul class="pageitem">
<li class="smallfield"><span class="name">latitude</span><input
placeholder="" id="latitude" name="latitude" type="num" />
</li></ul>
<ul class="pageitem">
<li class="smallfield"><span class="name">Longitude</span><input
placeholder="" id="longitude" name="longitude" type="num" />
</li></ul>
Лучшая документация, которую я нашел, это:
Как мне собрать данные из div для использования в форме
Но я не могу заставить это работать. Спасибо всем заранее.
