<i>ol.control.SearchFeature</i> is a control to search features in a source.
|
|
<ul>
|
|
<li>
|
|
You have to define a <i>ol.source.Vector</i> to search in.
|
|
</li>
|
|
<li>
|
|
You can define a <i>property</i> that will be used to search in or define a getTitle/getSearchString function.
|
|
</li>
|
|
<li>
|
|
You can define a <i>getTitle</i> to get the string that will be displayed in the menu
|
|
</li>
|
|
<li>
|
|
You can define a <i>getSearchString</i> function that will take a feature and
|
|
return a string to search in.

</li>
|
|
</ul>
