There are various different ways of using iShare to integrate maps within a website. Have a look at the following examples:
...
Again, zoom_value is the backwards compatible width of the map in metres. If any of the parameters are not passed then all three are ignored (note this is different to the jQuery method)
| Code Block |
|---|
|
?StartEasting=easting_value&StartNorthing=northing_value &StartZoom=zoom_value |
...
| Code Block |
|---|
|
window.astun.mapWrapper.searchISMLayer( layer, field, value, function( response ) {
window.astun.mapWrapper.showResults( response );
} ); |
...
Set the Scale for the Map
The previous methods for a point can be used provided you know the width in metres you want to zoom to.
JavaScript
You can zoom to a scale or zoom level using the OpenLayer map object window.astun.mapWrapper.map and manipulate it directly.
| Code Block |
|---|
| title | JavaScript - Zoom to Scale |
|---|
|
astun.mapWrapper.map.zoomToScale() |
and
| Code Block |
|---|
|
astun.mapWrapper.map.zoomTo() |
See full list of methods at: http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLayers/Map-js.htmldocs/index/General.html.| Note |
|---|
This method of access to the map is deprecated and may be removed in future versions - but only once we provide alternative methods of getting to the map object. |
Add or Remove Layers from the Map
A full list of available layers can be found in your map configuration in iShare Studio; the layers are under Map Sources. The layer names are case-sensitive.
JQuery
| Code Block |
|---|
|
jQuery('#atMap').trigger('showLayer',[layer_name]) jQuery('#atMap').trigger('hideLayer',[layer_name]) jQuery('#atMap').trigger('toggleLayer',[layer_name]) |
Only one layer can be specified at a time.
JavaScript
| Code Block |
|---|
|
window.astun.mapWrapper.addISMLayer(layer_name); window.astun.mapWrapper.removeISMLayer(layer_name); window.astun.mapWrapper.setISMLayers(layer_names); |
layer_names in the last method are a comma separated list and replace the existing set of layers on the map. You can get the current set of layers too:
| Code Block |
|---|
| title | Get Current set of Layers |
|---|
|
window.astun.mapWrapper.getISMLayers(); |
URL
or
| Code Block |
|---|
|
?layers=layer_names |
These are equivalent, layer_names are a comma separated list.
