How can i loaddata in store from a url?

[chenzhaoplus]

my code is:

        Ext.Ajax.request({
                url : 'http://localhost:8080/admin-web/jsonservice/foodEmbranchmentService.json',
                method : 'POST',
                jsonData : {
                    jsonrpc : "2.0",
                    id : 10,
                    method : "findAll"
                },
                success : function(result, request) {
                    var resultStr = result.responseText;
                    var jsonObj = Ext.decode(resultStr);
                    var jsonStr = Ext.encode(jsonObj);
                    store.loadData(jsonObj.result.resultList);
                },
                failure : function(form, action) {
                    Ext.MessageBox.alert("JSON Test", "JSON Failed！");
                }
            });

Ext.define('MyApp.stores.CanyindanweiStore', {
    extend : 'Ext.data.Store',
    singleton : true,
    requires : ['MyApp.models.CanyindanweiModel'],


    model : 'MyApp.models.CanyindanweiModel',
    remoteSort : false,
    storeId : 'canyindanweiStore'
});

i don't use proxy but Ext.ajax.requst in store because proxy can not post jsonData to url.If i loaddata in store,the data can show in gridpanel,the problem is when i select a record,i can not get a record from selectionmodel.

Why don't you use ajax proxy with extraParams config.

Ext.define('MyApp.stores.CanyindanweiStore', {
    extend : 'Ext.data.Store',
    singleton : true,
    requires : ['MyApp.models.CanyindanweiModel'],
    model : 'MyApp.models.CanyindanweiModel',
    remoteSort : false,
    storeId : 'canyindanweiStore',
    proxy: {
        type: 'ajax',
        url: 'http://localhost:8080/admin-web/jsonservice/foodEmbranchmentService.json',
        method: 'POST',
        extraParams: {
            jsonrpc : "2.0",
            id : 10,
            method : "findAll"
        },
        reader: {
            type: 'json',
            root: 'root'
        }
    }
});
