[英]fitBounds in PrimeFaces gmap component
Is there a way to call fitBounds method in the google map object created by PrimeFaces gmap component ? 有没有一种方法可以在PrimeFaces gmap组件创建的google map对象中调用fitBounds方法? I tried the code below, but get javascript error:
TypeError: primefacesMap.fitBounds is not a function
. 我尝试了下面的代码,但遇到javascript错误:
TypeError: primefacesMap.fitBounds is not a function
。 It appears that fitBounds
is overriden by a boolean property by PrimeFaces framework. 似乎
fitBounds
被PrimeFaces框架的布尔属性覆盖。
<h:head>
<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"/>
<script type="text/javascript">
//<![CDATA[
function initPrimefacesComponent(){
var primefacesMap = gmtls.getMap();
var bounds = new google.maps.LatLngBounds();
var points = [
new google.maps.LatLng(41.3, 2),
new google.maps.LatLng(41.309, 2)
];
// Extend bounds with each point
for (var i = 0; i < points.length; i++) {
bounds.extend(points[i]);
new google.maps.Marker({position: points[i], map: primefacesMap});
}
// Apply fitBounds
primefacesMap.fitBounds(bounds);
}
//]]>
</script>
</h:head>
<h:body onload="initPrimefacesComponent();" >
<p:gmap center="41.3, 2" zoom="15" type="ROADMAP" widgetVar="gmtls"
style="width:600px;height:400px" />
</h:body>
Below is the code that works for google map object that is created without primefaces: 以下是适用于创建的没有质数的google map对象的代码:
<h:head>
<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"/>
<script type="text/javascript">
//<![CDATA[
function initOriginalMap() {
var mapOptions = {
center: new google.maps.LatLng(41.3, 2),
zoom: 15
};
var originalMap = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
var bounds = new google.maps.LatLngBounds();
var points = [
new google.maps.LatLng(41.3, 2),
new google.maps.LatLng(41.309, 2)
];
// Extend bounds with each point
for (var i = 0; i < points.length; i++) {
bounds.extend(points[i]);
new google.maps.Marker({position: points[i], map: originalMap});
}
// Apply fitBounds
originalMap.fitBounds(bounds);
}
google.maps.event.addDomListener(window, 'load', initOriginalMap);
//]]>
</script>
</h:head>
<h:body >
<div id="map-canvas" style="width:600px;height:400px"/>
</h:body>
To make fitBounds
work in PrimeFaces I had to override again the fitBounds property of the map by original source: 为了使
fitBounds
在PrimeFaces fitBounds
工作,我不得不通过原始来源再次覆盖地图的fitBounds属性:
//remember the property set by PrimeFaces
var tmp = map.fitBounds;
//replace the code by the one provided by google maps api
map.fitBounds = google.maps.Map.prototype.fitBounds;
//execute fitBounds function
this.fitBounds(bounds);
//restore PrimeFaces property (probably PrimeFaces use it somehow)
this.fitBounds = tmp;
I submitted a PR to have this fixed natively in PF 7.1+. 我提交了一份PR,以在PF 7.1+中进行本地修复。 The fitBounds method will now be right on the widget itself.
现在,fitBounds方法将直接在小部件本身上。
