Question

有些人可以告诉我,如何把数据从控制器传送到塞察触点的数据储存。

观点守则

var select = new Ext.form.Select({
    id: selectCity ,
    store: parking.stores.city,
    displayField:  Name ,
    valueField:  Name ,
    placeHolder:  Choose City ,
    cls: select 
});

var citySearchButton = new Ext.Button({
    cls:  citySearch ,
    text:  Search ,
    handler: function () {
        Ext.dispatch({
            controller: parking.controllers.controller,
            action:  showMapBasedOnCity ,
            id: Ext.getCmp( selectCity ).getValue()
        });
    }
});

从我的观点看,我能够把价值传给控制员。

 showMapBasedOnCity: function (options) {
        var city = options.id;
        //var data = parking.stores.parkingFacilityByCity.setId(city);
        // parking.views.map.addMap(city);
        parking.views.viewport.setActiveItem(
            parking.views.map, options.animation
        );

    },

The problem is how to pass the value from here to the data store : I need the parameter from controller (the city value) to pass to my jsonp query to get the desired result back).

parking.stores.parkingFacilityByCity = new Ext.data.Store({
    model:  PF ,
    proxy: Ext.util.JSONP.request({
        url:  http://parking.511.org/index/M_GetParkingFacilityByCity ,
        callbackKey:  callback ,
        parmas: { city: },
        scope: this,
        callback: function (data) {
            var list = data.Root;
            parking.stores.parkingFacilityByCity.loadData(data.Root);
        }
    })
});

任何帮助都将受到高度赞赏。

In my Form on button click i get the value from and pass it on to the dispatch method. In the dispatch method i call the controller.

var select = new Ext.form.Select({
    id: selectCity ,
    store: parking.stores.city,
    displayField:  Name ,
    valueField:  Name ,
    placeHolder:  Choose City ,
    cls: select 
});

var citySearchButton = new Ext.Button({
    cls:  citySearch ,
    text:  Search ,
    handler: function () {
        Ext.dispatch({
            controller: parking.controllers.controller,
            action:  showMapBasedOnCity ,
            id: Ext.getCmp( selectCity ).getValue()
        });
    }
});

在控制器中,这种方法通过城市进入停车场,使新数据输入仓库。

  showMapBasedOnCity: function (options) {
        var city = options.id;
        getParkingFacilityByCity(city);
     //   parking.views.map.addMap();
        parking.views.viewport.setActiveItem(
            parking.views.map, options.animation
        );

数据档案

parking.stores.parkingFacilityByCity = new Ext.data.Store({
    model:  PF ,
    autoload: true
});

var getParkingFacilityByCity = function (cityName) {
    Ext.util.JSONP.request({
        url:  http://parking.511.org/index/M_GetParkingFacilityByCity ,
        callbackKey:  callback ,
        params: { city: cityName },
        callback: function (data) {
            parking.stores.parkingFacilityByCity.loadData(data.Root);
        }
    });
};

希望有助于有些人。可能还有其他方法。但是,这是对我来说很出色的工作。
