Question

我正在尝试将值传递给PHP服务器端。我的商店代码如下;

Ext.define('MyApp.store.MyArrayStore', {
    extend: 'Ext.data.Store',

    requires: [
        'MyApp.model.MyMOD'
    ],

    config: {
        autoLoad: true,
        model: 'MyApp.model.MyMOD',
        storeId: 'MyArrayStore',
        proxy: {
            type: 'ajax',
            actionMethods: 'POST',
            url: 'http://localhost/mm/app/php/res.php',
            reader: {
                type: 'json'
            }
        },
        listeners: [
            {
                fn: 'onArraystoreBeforeLoad',
                event: 'beforeload'
            }
        ]
    },

    onArraystoreBeforeLoad: function(store, operation, eOpts) {
        this.proxy.extraParams.VALUES1 = "pass some name here"; 
    }

});

PHP代码

<?php
error_reporting(E_ERROR | E_PARSE);

require_once 'conn.php'; // contains the connection

$v = $_POST['VALUES1'];
echo json_encode($v);

?>

返回的是null，而不是我从商店传递的值（pass some name here）。

我该如何纠正？

Answer 1

您需要更改设置extraParams的方式..在这种情况下我将使用

  store.getProxy().setExtraParam('VALUES1','pass some name here');

如果您需要发送多个参数，请使用setExtraParams

  var param = { VALUES1: 'param1', VALUES2 : 'param2'};
  store.getProxy().setExtraParams(param);

如此完整的商店代码

Ext.define('MyApp.store.MyArrayStore', {
    extend: 'Ext.data.Store',

    requires: [
        'MyApp.model.MyMOD'
    ],

    config: {
        autoLoad: true,
        model: 'MyApp.model.MyMOD',
        storeId: 'MyArrayStore',
        proxy: {
            type: 'ajax',
            actionMethods: 'POST',
            url: 'http://localhost/mm/app/php/res.php',
            reader: {
                type: 'json'
            }
        },
        listeners: [
            {
                fn: 'onArraystoreBeforeLoad',
                event: 'beforeload'
            }
        ]
    },

    onArraystoreBeforeLoad: function(store, operation, eOpts) {
        store.getProxy().setExtraParam('VALUES1 ','pass some name here');
    }

});

Answer 2

而不是this.proxy尝试this.getProxy()。

我发现控制台对于这类事情非常有用。在我自己的应用程序中运行Ext.getStore('MyStore').proxy;让我未定义，而Ext.getStore('MyStore').getProxy()让我成为我的代理。

使用控制台，对我而言，它是API旁边最有价值的开发工具。
