|
|
|

<p>Map properties include interaction handlers that allow you to control interaction behavior in runtime, enabling or disabling certain features such as dragging or touch zoom (see <a href="#ihandler">IHandler</a> methods). Example:</p>
|
|
|
|
<pre><code class="javascript">map.doubleClickZoom.disable();</code></pre>
|
|
|
|
<p>You can also access default map controls like attribution control through map properties:</p>
|
|
|
|
<pre><code class="javascript">map.attributionControl.addAttribution("Earthquake data &copy; GeoNames");</code></pre>

<h2 id="popup">L.Popup</h2>
|

<p>Used to open popups in certain places of the map. Use <a href="#map-openpopup">Map#openPopup</a> to open popups while making sure that only one popup is open at one time (recommended for usability), or use <a href="#map-addlayer">Map#addLayer</a> to open as many as you want.</p>

<h3>Usage example</h3>

<p>If you want to just bind a popup to marker click and then open it, it's really easy:</p>
|
|
<pre><code class="javascript">marker.bindPopup(popupContent).openPopup();</code></pre>
|
|
<p>Path overlays like polylines also have a <code>bindPopup</code> method. Here's a more complicated way to open a popup on a map:</p>
|
|
<pre><code class="javascript">var popupContent = '<p>Hello world!<br />This is a nice popup.</p>',
|
|
popup = new L.Popup();
|
|
|
|
popup.setLatLng(latlng);

popup.setContent(popupContent);

|
map.openPopup(popup);</code></pre>
