【问题描述】:
我设法(在 SO 的帮助下)将 pulsing 标记从插件放到带有 R 传单包的地图中,并使用以下脚本:
library(leaflet)
library(htmltools)
library(htmlwidgets)
# This tells htmlwidgets about our plugin name, version, and
# where to find the script. (There's also a stylesheet argument
# if the plugin comes with CSS files.)
esriPlugin <- htmlDependency("leaflet-icon-pulse",version = "1.0",
src = "realtimemap/",
script = "L.Icon.Pulse.js",stylesheet ="L.Icon.Pulse.css")
# A function that takes a plugin htmlDependency object and adds
# it to the map. This ensures that however or whenever the map
# gets rendered, the plugin will be loaded into the browser.
registerPlugin <- function(map, plugin) {
map$dependencies <- c(map$dependencies, list(plugin))
map
}
content <- paste(sep = "<br/>",
"<b><a> Homicide </a></b>",
"606 5th Ave. S",
"Ocean District, CA 98138"
)
leaflet() %>% addProviderTiles("CartoDB.DarkMatter") %>% setView(-122.4105513,37.78250256, zoom = 12) %>%
addPopups(-122.41, 37.78, content,
options = popupOptions(closeButton = TRUE)
) %>%
registerPlugin(esriPlugin) %>%
# Add your custom JS logic here. The `this` keyword
# refers to the Leaflet (JS) map object.
onRender("function(el,x) {
var pulsingIcon = L.icon.pulse({iconSize:[20,20],color:'red'});
var pulsingIcon2 = L.icon.pulse({iconSize:[15,15],color:'orange',heartbeat:2});
var marker = L.marker([37.78,-122.41],{icon: pulsingIcon}).addTo(this);
var marker = L.marker([37.75,-122.39],{icon: pulsingIcon2}).addTo(this);}")
但是现在,如果我点击那些脉冲标记,我想显示一些信息。当然,我不能使用传单包中的 addpopup 或 addmarker,因为我必须使用非正统的方式从插件中添加标记。你会怎么做?
【问题讨论】:
-
为什么不在同一位置添加一个带有所需弹出窗口的透明圆圈标记?
-
哇还不错。我要试试!!
-
@TimSalabim 真可惜,我似乎无法将圆形标记放在脉冲标记的顶部。
-
确实可惜。我明天看看。也许我们可以用 z-index 做点什么。
-
Z 索引?好的,谢谢你的帮助,再见
