ExtJS store.loadData() doesn't load the JSON data
提问by Arya Mz
I am trying to load a JSON data which is replied back by an AJAX request to a grid. My store definition:
我正在尝试加载一个 JSON 数据，该数据由对网格的 AJAX 请求回复。我的店铺定义：
Ext.define('Report.store.CustomerDataStore', {
extend: 'Ext.data.Store',
requires: [
'Report.model.Customer'
],
constructor: function(cfg) {
var me = this;
cfg = cfg || {};
me.callParent([Ext.apply({
autoLoad: false,
storeId: 'CustomerDataStore',
model: 'Report.model.Customer',
proxy: {
type: 'ajax',
url: '',
reader: {
type: 'json',
root: 'data',
record: 'fields'
}
}
}, cfg)]);
}
});
There is a button in my app which is defined as follows:
我的应用程序中有一个按钮，其定义如下：
xtype: 'button',
handler: function(button, event) {
var queryform = this.up('form').getForm();
var me = this;
if(queryform.isValid())
{
Ext.Ajax.request({
url: 'customers/', // where you wanna post
success: function(response) {
var mystore = Ext.data.StoreManager.lookup('CustomerDataStore');
var myData = Ext.JSON.decode(response.responseText);
console.log(myData.toSource());
mystore.loadData(myData);
},
jsonData: Ext.JSON.encode(queryform.getValues())
});
}
},
The problem is that my grid doesn't show the replied data! I am sure that my replied JSON format is OK. I have checked it with a json file. also myData.toSource()returns my desired JSON format.
I am pretty confused what I am doing wrong?
问题是我的网格没有显示回复的数据！我确定我回复的 JSON 格式没问题。我已经用 json 文件检查过它。还myData.toSource()返回我想要的 JSON 格式。我很困惑我做错了什么？

I found the solution, I had to use loadRawData() function instead of loadData().
我找到了解决方案，我不得不使用 loadRawData() 函数而不是 loadData()。

loadData()loads models i.e. records, and doesn't parse JSON data inside. You need to specify your JSON format in proxy reader and then store will automatically do Ajax call when you call store.load()
loadData()加载模型即记录，并且不解析内部的 JSON 数据。您需要在代理阅读器中指定您的 JSON 格式，然后存储会在您调用时自动进行 Ajax 调用store.load()
