如何在beforeload事件上获取Extjs 4商店的请求数据?

问题描述

我正在尝试在商店的加载事件之前获取请求数据参数.我可以看到操作对象包含请求数据，但我似乎无法从操作对象中获取它

I'm trying to get request data params beforeload event on store. I can see the operation object contains the request data but I can't seems to get it from operation object

Ext.create('Ext.data.Store', {
    autoLoad : true,
    fields   : [
        {name: 'item_code',             type: 'string'},
        {name: 'quantity',              type: 'int'},
        {name: 'description',           type: 'string'}
    ],
    storeId  : 'summary',
    proxy    : {
        type            : 'ajax',
        actionMethods   : 'POST',
        extraParams     : {'filter': 'branch', 'branch': location },
        url             : 'reports/stock_summary',
        reader: {
            type    : 'json',
            root    : 'data'
        }
    },
    listeners: {
        beforeload: function(store, operation, options){
            console.log( operation )
        }
    }
});

知道如何在加载事件之前获取请求对象并获取该请求对象中的数据吗?

我认为这可以帮助你......

i think this could help you ...

var test = Ext.create('Ext.data.Store', {
        autoLoad : true,
        fields   : [
            {name: 'item_code',             type: 'string'},
            {name: 'quantity',              type: 'int'},
            {name: 'description',           type: 'string'}
        ],
        storeId  : 'summary',
        proxy    : {
            type            : 'ajax',
            actionMethods   : 'POST',
            extraParams     : {'filter': 'branch', 'branch': location },
            url             : 'reports/stock_summary',
            reader: {
                type    : 'json',
                root    : 'data'
            }
        },
        listeners: {
            beforeload: function(store, operation, options){
                console.log( 'manual load ' + operation.params );
                console.log( operation.params );
                console.log( 'proxy defined params ' + store.proxy.extraParams );
                console.log( store.proxy.extraParams )
            }
        }
    });

    test.load({params: {test: '123'}});
