Javascript 如何将数据从mapbox提取到html页面
我正在使用Mapbox gl js。我正在控制台中获取数据,但我无法将数据提取到HTML中,有人能帮我这样做吗。 我需要数据,在mapdata中显示在html页面上,当我单击标记时,showStory条件必须为true。我尝试使用ngFor使用mapData,但它不起作用,当我在mapbox外使用console时,console中的数据也不会出现 HTML:Javascript 如何将数据从mapbox提取到html页面,javascript,mapbox-gl-js,Javascript,Mapbox Gl Js,我正在使用Mapbox gl js。我正在控制台中获取数据,但我无法将数据提取到HTML中,有人能帮我这样做吗。 我需要数据,在mapdata中显示在html页面上,当我单击标记时,showStory条件必须为true。我尝试使用ngFor使用mapData,但它不起作用,当我在mapbox外使用console时,console中的数据也不会出现 HTML: 地名 乡村、城市 邮政编码、地址 Ts: publicshowstory:boolean=false; 这是我们的服务 .get

如果要将数据从组件显示到HTML
,请使用innerHTML
属性
在html中
<li><b [innerHTML]="place"></b></li>
<li [innerHTML]="Country, City"></li>
<li [innerHTML]="Postal Code, Address"></li>
我不知道你想做什么。你能详细解释一下吗?出什么问题了?感谢您的回复,这里是console.log(this.mapData),我正在获取数据。。我需要从那里获取名称并将该名称添加到html中page@SteveBennettㄹ谢谢你的回复。。这有帮助
