我在一页上有一个简单的文本提交字段。目的是让用户键入一个位置并点击“提交”，然后转到带有Mapbox地图的登录页面，使其居中或缩放到该位置。我尝试使用一个变量从本地存储传递地址-获取本地存储项并将其设置为地图中心-不走运。然后将其设置为新Mapbox地图的中心。我也可以使用Mapbox中的flyto方法来飞到地址位置。我不确定这是否会破坏地址解析器。这是我的代码：
第一页：
<html>
<form target="_blank" id="form1">
<input name="address" type="text" id="address" placeholder="Location" style="border-radius: 5px;"/>
<input onclick="window.location.href = 'mymapboxpage';" type="Submit" value="GO" style="border-radius: 5px;"/>
</form>
</div>
<script type="text/javascript">
document.getElementById('form1')
.addEventListener('submit', function (event) {
event.preventDefault();
localStorage.setItem('address', document.getElementById('address').value);
});
</script>
</html>
带有Mapbox地图的着陆页：
