Can't Display Polylines on a Google Map

You can use the Google Maps on your own website to provide a range of useful services. One feature available via the API is the polyline feature to join two markers using a line. This has many good uses where two markers need to be associated with each other.


Unfortunately there is a common problem where the polyline wont display , and there will be no obvious error messages. After some research a fix was found to this problem.

This issue is more likely to occur in Internet Explorer.


Place to following code inside the <head> tag of your page

<style type="text/css"> 
v\:* {

Also , use :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "">
<html xmlns="" xmlns:v="urn:schemas-microsoft-com:vml">

in the header instead of....

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
<html xmlns="">
