问题描述
autoUpdate:false;
但是我真的不知道该怎么做... 是我的代码
Ext.application({
name:'Applicatie3。',
launch:function (){
var view = Ext.create('Ext.NavigationView',{
fullscreen:true,
items:[{
title:I'm lost,
xtype:'tabpanel',
items:[{
title:'Home',
xtype:'map',
iconCls:'home',
mapOptions:{zoom:20},
useCurrentLocation:true,
listeners:{
maprender:function(comp,map){
var marker = new google.maps。标记({
position:new google.maps.LatLng(),
map :map
}),
infowindow = new google.maps.InfoWindow({
content:'........'
}),
route = [],
geo = Ext.create('Ext.util.Geolocation',{
frequency:3000,
autoUpdate:true,
allowHighAccuracy:true,
listeners:{
locationupdate:function(geo){
polyline = new google.maps.Polyline({
path:route,
strokeColor:red,
strokeOpacity:1.0,
strokeWeight:5
} );
polyline.setMap(map),
// alert(route);
route.push(new google.maps.LatLng(geo.getLatitude(),geo.getLongitude()));
marker.setPosition(new google.maps.LatLng(geo.getLatitude(),geo.getLongitude()));
google.maps.event.addListener(marker,'click',function(){
infowindow.open(map,marker);
});
},
locationerror:function(geo,bTimeout,bPermissionDenied,bLocationUnavailable,message){
if(bTimeout){
alert('超时发生) ;
} else {
alert('Error occurred。');
}
}
}
});
geo.updateLocation();
}
}
}]
}]
});
}
});
解决方案
我用一个设置为false的全局变量解决了这个问题,当我按下开始按钮,然后变量变为true。在函数中,我有一个if(true){do location update},当变量设置为false时,位置更新不起作用。
Can someone please help me? I have a map in sencha that can track my current location and it draws lines. But I also want a button to stop tracking. So I want to set autoUpdate: false;
But I seriously dont know how to do this...
This is my code
Ext.application({
name: 'Applicatie3.',
launch: function() {
var view = Ext.create('Ext.NavigationView', {
fullscreen: true,
items: [{
title: "I'm lost",
xtype: 'tabpanel',
items:[{
title : 'Home',
xtype : 'map',
iconCls : 'home',
mapOptions : { zoom: 20 },
useCurrentLocation : true,
listeners : {
maprender: function(comp, map){
var marker = new google.maps.Marker({
position : new google.maps.LatLng( ),
map : map
}),
infowindow = new google.maps.InfoWindow({
content : '........'
}),
route = [ ],
geo = Ext.create('Ext.util.Geolocation', {
frequency : 3000,
autoUpdate : true,
allowHighAccuracy : true,
listeners : {
locationupdate : function(geo) {
polyline = new google.maps.Polyline({
path : route,
strokeColor: "red",
strokeOpacity: 1.0,
strokeWeight: 5
});
polyline.setMap(map),
//alert(route);
route.push( new google.maps.LatLng( geo.getLatitude(),geo.getLongitude() ) );
marker.setPosition(new google.maps.LatLng( geo.getLatitude(),geo.getLongitude() ) );
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map, marker);
});
},
locationerror: function(geo, bTimeout, bPermissionDenied, bLocationUnavailable, message) {
if(bTimeout){
alert('Timeout occurred.');
} else {
alert('Error occurred.');
}
}
}
});
geo.updateLocation();
}
}
} ]
}]
});
}
});
解决方案
I solved this problem with a global variable which is set false and when I press the start button then the variable change to true. In the function I have a if(true) {do location update}, when the variable is set false then the location update don't work.
