Zoom on an object when opening the map
Some URL parameters are available to be able to zoom in on one or more objects and display their popup:
layer
, layer name in WFS and WMS servicesfilter
, layer filter to initiate the zoompopup=true
, boolean to display the popup(s) of the filtered objects
The layer and filter parameters will be used for WFS and WMS type queries, so make sure that these are well compatible with the 2 types of services.
For instance, we would like to reuse the map of Montpellier showing cadastral by providing a customized link opening the popup from the Park of Peyrou in the city center.
This park has 340172000BX0079
for its unique ID in the field geo_parcelle
, layer parcelle
.
Therefore, we need to add in the URL above :
layer=parcelle
filter=%22geo_parcelle%22%20%3D%20%27340172000BX0079%27
popup=true
It gives this final result :
For your information, we can have the value of the filter with the help of the JavaScript console in your web browser F12 :
encodeURIComponent("\"geo_parcelle\" = '340172000BX0079'")`
Совет
You should check other URL parameters which can be in the URL already. They can alter the behavior of the
described feature, for instance bbox=
.
