Leaflet zoom on locations using multiple links

由 半城伤御伤魂 提交于 2019-12-11 09:17:37
问题 I just ran into another problem using Leaflet. I want to zoom into specific locations using Links provided underneath the maps. With one link I got it to work fine but more Links don't work.

Could somebody maybe help with this problem? The locations are stored in tags: <div id="map-navigation" class="map

由 爱⌒轻易说出口 提交于 2019-12-11 04:51:41
问题 Essentially, I want to pull text within a div tag from a document on my server to place it in the current document. To explain the reason: I want to pull a headline from a "news article" to use it as the text for a link to that article. For example, within the target HTML is the tag: <div id='news-header'>Big Day in Wonderland</div> So in my current document I want to use javascript to set the text within my anchor tags to that headline, i.e.: <a href='index.php?link=to_page'>Big Day in
