<div class="info">
|
|
<i>ol.control.Permalink</i> is hyperlink that will return the user to the current map view.
|
|
<br/>
|
|
The href is updated as the map is zoomed, panned, rotated and whilst layers are switched or opacity is changed
|
|
(as soon as the layer has a <i>permalink</i> propertie).
|
|
<ul><li>
|
|
Use <i>geohash</i> options to use a <a href="../geom/map.geohash.html">geohash</a>
|
|
instead of lonlat coordinates in url.
|
|
</li><li>
|
|
Use <i>urlReplace</i> option to activate the url replacement.
|
|
</li><li>
|
|
Use <i>localStorage</i> option to save the the current map view in the localstorage.
|
|
<br/>
|
|
Information in the url has priority over the localStorage, ie. localStorage is used if no information
|
|
is provided in the url or if <i>urlReplace</i> option is set to false.
|
|
</li><li>
|
|
You can hide the control on the map using the <i>hidden</i> option.
|
|
</li><li>
|
|
Only layers with a <i>permalink</i> properties are handled by the control.
|
|
The permalink propertie is used to name the layer in the url.
|
|
</li><li>
|
|
By default, clicking the control will enable/disable the url replacement.
|
|
Use the <i>onclick</i> option to change this behavior (mail to a friend...).
|
|
</li><li>
|
|
Use <i>getUrlParam</i>, <i>setUrlParam</i> or <i>hasUrlParam</i> methods
|
|
to get, add or test user parameters in the url and handle new functionnalities
|
|
(layers opacity, visibility, ordering, etc.)
|
|
