问题描述

我正在使用extjs sencha存储来存储数据。我对Web服务进行代理调用以获取数据。我使用store.load()函数刷新数据。



我正在寻找在给予网格之前收到的数据。



我知道加载事件,但是这个函数在加载完成后被执行,数据被填充当前数据。

 听众:{
'load':function(store,records,options){
}
},

我正在寻找在分配给商店之前如何从Web服务编辑返回的数据。基本上从我的webservice返回的数据格式与我们给extjs datagrid的格式不同。所以,在我们给网格之前,要做一个数据操作。希望我们可以做到这一点。



Thx

解决方案

模型映射可以帮你做这个还有一个可以提供的转换功能。以下是文档

  Ext.define('User',{
extends:'Ext.data.Model',
字段:[
{
名称:'firstName',
convert:function(value,record){
var fullName = record.get('name'
splitits = fullName.split(),
firstName = splitits [0];

return firstName;
}
},
'name','email',
{name:'age',type:'int'},
{name:'gender',type:'string',defaultValue:'Unknown'}
]
});


I am using extjs sencha store for storing data. I make a proxy call to a web-service to get data. I refresh the data using store.load() function.

I am looking to edit the data that is received before it is given to the grid.

I know about the load event, but this function is executed after the load is completed and data is populated with the current data.

listeners : {
        'load' : function(store,records, options) {
    }
},

I am looking to see how I can edit the returned data from web-service before it is assigned to the store. Basically data returned from my webservice is in different format than the format we give to extjs datagrid. So, want to do a data operation before we give to the grid. Hope we can do this.

Thx

Model mappings can help you do this. There is a conversion function that can be supplied as well. Here is the example from the docs:

Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: [
        {
            name: 'firstName',
            convert: function(value, record) {
                var fullName  = record.get('name'),
                    splits    = fullName.split(" "),
                    firstName = splits[0];

                return firstName;
            }
        },
        'name', 'email',
        {name: 'age', type: 'int'},
        {name: 'gender', type: 'string', defaultValue: 'Unknown'}
    ]
});
