<div class="info">

Display a grid reference on the map and an index associated with.
|
|
<ul>
|
|
<li>
|
|
You have to define the <i>extent</i> and the <i>size</i> of the grid.
|
|
</li>
|
|
<li>
|
|
You can define a <i>ol.source.vector</i> or use the <i>setIndex</i> method to display an index.
|
|
</li>
|
|
<li>
|
|
You can define a <i>property</i> (or a function to retrieve it) that will be displayed in the index.
|
|
</li>
|
|
<li>
|
|
You can customize a <i>sortFeature</i> function and the <i>indexTitle</i>
|
|
that will be displayed in the index.
|
|
</li>
|
|
</ul>
|
|
<i>ol.control.GridReference</i> requires jQuery.
