Question

我试图模仿https://rstudio.github.io/leaflet/popups.html上的第一个例子，但是使用的是html标签的矢量而不是一个。

https://rstudio.github.io/leaflet/popups.html上的示例：

含量

[1] "<b><a href='http://www.samurainoodle.com'>Samurai Noodle</a></b><br/>606 5th Ave. S<br/>Seattle, WA 98138"

矿：

鸟$ HTML [1]

[1] "<a href=‘https://www.allaboutbirds.org/guide/Gadwall/id’>more info</a>"

但是，当我将代码传递给leaflet popup时，会显示更多的info超链接，并链接到未找到的页面而不是url。我是否必须在HTML标记中添加任何特殊字符（例如斜杠或引号）？有什么想法吗？

leaflet () %>%
      addTiles(urlTemplate = base_map, attribution = mb_attribution)%>%
      addMarkers(bird$lon, bird$lat, 
                 popup=paste(sep="","<b>", bird$Common.Name,"</b>",
                             "<br/>","<font size=2 color=#045FB4>","Scientific Name: ","</font>" ,bird$Scientific.Name,
                             "<br/>","<font size=2 color=#045FB4>","Number Observed: ","</font>", bird$Count,
                             "<br/>","<font size=2 color=#045FB4>","Location: ","</font>", bird$Location,
                             "<br/>","<font size=2 color=#045FB4>","Region: ","</font>", bird$Area,
                             "<br/>","<font size=2 color=#045FB4>", "Date: ", "</font>", bird$Date,
                             "<br/>", bird$html),
                 clusterOptions = markerClusterOptions()) %>%
      addPopups(bird$lon, bird$lat, bird$html, options = popupOptions(closeButton = FALSE)
      )

我认为您使用的是错误的引号字符串。 ’代替'。如果我将引号字符串反转为：

，它对我有用

'<a href="https://www.allaboutbirds.org/guide/Gadwall/id">more info</a>'

双引号以转义网址。

R，传单包，将HTML标签的字符向量传递给弹出窗口？
