ExtJs4 - 存储 baseParams 配置属性? [英] ExtJs4 - Store baseParams config property?

问题描述

在 extjs3.x 中，我使用商店 baseParams 配置属性来指定用于加载商店的参数.
这个属性在 extjs 4 中不再存在.我应该怎么做而不是这个?

In extjs3.x I used the stores baseParams config property to specify parameters used to load the store.
This property no longer exists in extjs 4. What should I do instead of this?

也在 extjs3 中，我能够通过使用代理 method 配置属性来指定商店代理是 GET 还是 POST 方法.我应该怎么做而不是这个?

Also in extjs3 I was able to specify wether the stores proxy was a GET or a POST method by using the proxy method config property. What should I do instead of this?

我的 ExtJs 3 代码 ->

My ExtJs 3 code ->

   var store = new Ext.data.JsonStore({
        root: 'Data',
        baseParams: {
           StartDate: '',
           EndDate: '''
        },//baseParams
    proxy: new Ext.data.HttpProxy({
        url: 'Time/Timesheet',
        method: 'POST'
    })//proxy
});//new Ext.data.JsonStore

推荐答案

您需要使用extraParams"代理属性来代替 Ext 3 中的 baseParams 代理属性.ExtJS 4 中的等效 JsonStore 如下所示:

You need to use the 'extraParams' proxy property in place of the baseParams one from Ext 3. An equivalent JsonStore in ExtJS 4 looks like this:

Ext.define('YourModel', {
    extend: 'Ext.data.Model',
    fields: ['field1', 'field2']
}); 

var store = new Ext.data.Store({
    model: 'YourModel',
    proxy: {
        type: 'ajax',
        url : 'Time/Timesheet',
        root: 'Data',
        extraParams: {
            StartDate: '',
            EndDate: ''
        }
    }
});

据我所知，HTTP 传输方法是根据 RESTful 原则根据您要完成的任务自动设置的.例如，如果您加载商店，则使用 GET 请求；创建新记录使用 POST 等

As far as I know, the HTTP transport method is set automatically according to RESTful principles according to what you're trying to accomplish. For example, if you load the store a GET request is used; creating a new record uses a POST, etc.

如有必要，您可以通过覆盖代理的 actionMethods 属性来覆盖它:

You can override this if necessary though, by overriding the actionMethods property of the proxy:

var store = new Ext.data.Store({
    model: 'YourModel',
    proxy: {
        type: 'ajax',
        url : 'Time/Timesheet',
        root: 'Data',
        actionMethods: {
            read: 'POST'
        },
        extraParams: {
            StartDate: '',
            EndDate: ''
        }
    }
});
