Extjs 获取要放置在代理中的地理位置变量
我正在尝试将设备的当前位置添加到代理调用中。我已经添加了带有“+radius+”和“+values+”的变量。我使用了Ext.util.Geolocation,可以在控制台中看到地理位置。如何从中获取lat和long变量,以便添加到代理中,如“+lat+”和“+lon+”Extjs 获取要放置在代理中的地理位置变量,extjs,sencha-touch-2,Extjs,Sencha Touch 2,我正在尝试将设备的当前位置添加到代理调用中。我已经添加了带有“+radius+”和“+values+”的变量。我使用了Ext.util.Geolocation,可以在控制台中看到地理位置。如何从中获取lat和long变量,以便添加到代理中,如“+lat+”和“+lon+” Ext.define('FirstApp.controller.History', { extend:'Ext.app.Controller', config:{ refs:{ main:'main'

首先,给你的代理提供id,这样我们就可以随时通过id访问它
var proxy = {
type:'ajax',
id:'myPlaceProxy',
url:'https://maps.googleapis.com/maps/api/place/search/json?location=52.247983,-7.141113&radius='+radius+'&types='+values+'&name=&sensor=false&key=',
reader:{
type:'json',
rootProperty:'results'
}
}
然后在地理位置的locationupdate事件中访问代理
var geo = new Ext.util.Geolocation({
autoUpdate: true,
allowHighAccuracy: true,
listeners: {
locationupdate: function(geo) {
lat = geo.getLatitude();
lon = geo.getLongitude();
var proxy = Ext.getCmp('myPlaceProxy');
proxy.setUrl('https://maps.googleapis.com/maps/api/place/search/json?location='+lat+','+lon+'&radius='+radius+'&types='+values+'&name=&sensor=false&key='');
console.log(proxy);
Ext.StoreMgr.get('Places').setProxy(proxy);
Ext.StoreMgr.get('Places').load();
}
}
});
然后在需要时通过调用此
geo.updateLocation();
编辑:
但我强烈建议不要总是制造风险
您只需调用这个geo.updateLocation();一旦您在全球范围内创建它,您就可以更好地管理它
试试这个:
Ext.define('FirstApp.store.Places',{
extend:'Ext.data.Store',
id: 'myPlaces',
config:{
autoLoad:false,
model:'FirstApp.model.Place',
proxy:{
type:'ajax',
url:'https://maps.googleapis.com/maps/api/place/search/json? location=52.247983,-7.141113&radius='+radius+'&types='+values+'&name=&sensor=false&key=AIzaSyAAStZvDJ_5ENODEdSCanLWgJBG6p6eXBQ',
reader:{
type:'json',
rootProperty:'results'
}
}
});
之后,您可以将tap事件中的url设置为
onSearchTap: function() {
Ext.Viewport.setActiveItem(Ext.create('FirstApp.view.Main'));
var values = this.getVisit().getValue();
var radius = this.getRadius().getValue() * 1000;
console.log(values);
console.log(radius);
var geo = new Ext.util.Geolocation({
autoUpdate: false,
allowHighAccuracy: true,
listeners: {
locationupdate: function(geo) {
lat = geo.getLatitude();
lon = geo.getLongitude();
Ext.StoreMgr.get('Places').getProxy().setUrl('https://maps.googleapis.com/maps/api/place/search/json?location='+lat+','+lon+'&radius='+radius+'&types='+values+'&name=&sensor=false&key='');
Ext.StoreMgr.get('Places').load();
}
}
});
geo.updateLocation();
}
你好,Mayur,我已经尝试了上面的方法,但是我得到了一个未捕获的错误TypeError:无法调用undefined的方法“setUrl”。如果你知道我哪里出错了,那是因为第一次没有创建代理,试着在地理位置编码上方创建代理,然后将其托管到sencha fiddle中。嘿,Mayur,我已经用你的代码更新了原始答案中的代码,并包含了两个js。我发布了新代码,如果这也不工作,然后主机上的sencha小提琴你的应用程序,让我知道
