问题
I'm working on a simple implementation of Python Folium with simple markers based on this page.
import folium
map_1 = folium.Map(location=[45.372, -121.6972], zoom_start=12,
tiles='Stamen Terrain')
map_1.simple_marker([45.3288, -121.6625], popup='Mt. Hood Meadows')
map_1.simple_marker([45.3311, -121.7113], popup='Timberline Lodge')
map_1.create_map(path='mthood.html')
I can include HTML in the popup, but I'd like to embed a webpage. Here is my mock-up.
Is it possible?

Here a quick example of how I proceed :
def get_frame(url,width,height):
html = """
<!doctype html>
<html>
<iframe id="myIFrame" width="{}" height="{}" src={}""".format(width,height,url) + """ frameborder="0"></iframe>
<script type="text/javascript">
var resizeIFrame = function(event) {
var loc = document.location;
if (event.origin != loc.protocol + '//' + loc.host) return;
var myIFrame = document.getElementById('myIFrame');
if (myIFrame) {
myIFrame.style.height = event.data.h + "px";
myIFrame.style.width = event.data.w + "px";
}
};
if (window.addEventListener) {
window.addEventListener("message", resizeIFrame, false);
} else if (window.attachEvent) {
window.attachEvent("onmessage", resizeIFrame);
}
</script>
</html>"""
popup = get_frame(url,
width,
height)
marker = folium.CircleMarker([lat,lon],
radius=radius,
color='#3186cc',
fill_color = '#3186cc',
popup=popup)
marker.add_to(map)
iframe = folium.element.IFrame(html=html,width=width,height=height)
popup = folium.Popup(iframe,max_width=width)
return popup
I took the script from this link, and you can check running the code snippet

I wanted to include html in popup="some text here", I have found that by default the folium module would escape all html syntax, so that it would display the actual syntax in the browser rather than processing it, so for example
'<' will becomes '&-l-t-;' without the dashes
I do not understand java whatsoever, so what I have done is: after the 'map.html' file is generated, I'd run another script to change the escape back into html syntax, this is dirty, the code is super bad, but its working for what I wanted to do.
def writeHTML(inputfile, outputfile):
readfile_first = open(inputfile,'r')
writefile_first = open(outputfile, 'w')
for line in readfile_first:
writefile_first.write(line.replace('<','<'))
readfile_first.close()
writefile_first.close()
readfile_second = open(outputfile, 'r')
writefile_second = open(inputfile, 'w')
for line in readfile_second:
writefile_second.write(line.replace('"','"'))
readfile_second.close()
writefile_second.close()
readfile_third = open(inputfile, 'r')
writefile_third = open(outputfile, 'w')
for line in readfile_third:
writefile_third.write(line.replace('>','>'))
readfile_third.close()
writefile_third.close()

It looks like it's possible with an iframe. I made a fiddle to test things out, but jsfiddle blocks my outgoing request for google.com and redirects back to jsfiddle login page. But it is a good proof of concept because it is loading an external page in the popup.
layer.bindPopup("<html><body><iframe src="http://www.google.com">
<p>Your browser does not support iframes.</p></iframe></body></html>");
I haven't tried it out but you could also try using jquery's load function.
