FusionMaps also allows you to open your links in pop up windows. To open a link in pop-up window, you need to define the link as under:

<entity .. value='235' link="P-detailsWin,width=400,height=300,toolbar=no,scrollbars=no, resizable=no-ShowDetails.asp%3FMonth%3DJan" />

Here, we've:

1. Prefixed the link with P- so as to denote that the link is to be opened in a new pop-up window.
2. Specified a name for the new window. In this case it's detailsWin. If you want all the links to open in the same pop-up, use the same window name across all links. However, if you want each link to open in a new pop-up, specify a different window name for each link.
3. After the name of the pop up window comes the list of attributes for the new window separated by commas. Possible list of attributes is defined below.
4. Finally, the actual link to be invoked is defined after a dash (-). Again, the link is URL Encoded.
