Question about MemoryProxy and Jsondata

[justmonkey]

I use MemoryProxy to load local jsondata, but there is no results in grid.



/*myconfig.js*/

var MyConditionConfig = function () {
var req, unConfigedStore, configedStore, columnModel, unConfigedGrid, configedGrid ;

return {
init : function() {

columnModel = new Ext.grid.ColumnModel([{
header: "Name",
dataIndex: 'name',
width: 100
}, {
header: "Type",
dataIndex: 'type',
width: 50
}]);

req = new ActiveXObject("Msxml2.XMLHTTP");
req.onreadystatechange = function () {
if (req.readyState == 4) {
if (req.status == 200){
var jsonData = Ext.util.JSON.decode( req.responseText );
var unConfigedData = jsonData.unConfiged;
var configedData = jsonData.configed;
var unConfigedCCData, configedCCData;
for ( var i=0; i<unConfigedData.length; i++ ){
var ccData = unConfigedData[i];
if ( ccData.cc == "testcc" ){
unConfigedCCData = ccData;
break;
}
}
for ( var i=0; i<configedData.length; i++ ){
var ccData = configedData[i];
if ( ccData.ccid == "testcc" ){
configedCCData = ccData;
break;
}
}
unConfigedStore = new Ext.data.Store({
proxy: new Ext.data.MemoryProxy(unConfigedCCData),
reader: new Ext.data.JsonReader({
root: 'items'
},[
{name: 'name', mapping: 'name' },
{name: 'type', mapping: 'type' }
])
});
configedStore = new Ext.data.Store({
proxy: new Ext.data.MemoryProxy(configedCCData),
reader: new Ext.data.JsonReader({
root: 'items'
},[
{name: 'name', mapping: 'name' },
{name: 'type', mapping: 'type' }
])
});

unConfigedGrid = new Ext.grid.Grid('unConfigedDiv', {
ds: unConfigedStore,
cm: columnModel,
selModel: new Ext.grid.RowSelectionModel({singleSelect:true}),
enableColLock:false
});
configedGrid = new Ext.grid.Grid('configedDiv', {
ds: configedStore,
cm: columnModel,
selModel: new Ext.grid.RowSelectionModel({singleSelect:true}),
enableColLock:false
});

unConfigedGrid.render();
configedGrid.render();

} else {
alert("HTTP error: " + req.status);
}
}
};
req.open("POST", "my_config.do?c=CONDITION_CONFIG_INIT", true);
req.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
req.send(null);

this.req= req;
this.unConfigedStore= unConfigedStore;
this.configedStore= configedStore;
this.columnModel= columnModel;
this.unConfigedGrid= unConfigedGrid;
this.configedGrid= configedGrid;

}
};
}();

Ext.EventManager.onDocumentReady(MyConditionConfig.init, MyConditionConfig, true);


And unConfigedCCData is


{"cc":"testcc", "items":[{"index":1,"type":"Attribute","name":"unconfigedaaa","nType":0,"id":"testid"},{"index":2,"type":"Attribute","name":"unconfigedbbb","nType":0,"id":"testid2"},{"index":3,"type":"AttributeGroup","name":"unconfigedccc","nType":1,"id":"testid3"}]}

ConfigedCCData is


{"cc":"testcc", "items":[{"index":1,"type":"Attribute","name":"configedaaa","nType":0,"id":"testid"},{"index":2,"type":"Attribute","name":"configedbbb","nType":0,"id":"testid2"},{"index":3,"type":"AttributeGroup","name":"configedccc","nType":1,"id":"testid3"}]}


But in my page, grid only have title colmns "Name", "Type". No results. Where I made a mistake? Thanks.

So it works now???

Why aren't you using HttpProxy?

Why are you using activex?

Why are you using activex?

Because i want to render two grids after one request to server. If i use HttpProxy, i may send two requests. I'm appreciate if you have better idea:)

OK, two different sets of data for two grids?

You should really use an Ext.data.Connection to get the data for efficiency and cross-browser utility.

Docs are not there yet, but soon will be. Meanwhile you can look at the source code to figure how to use it. And look at how HttpProxy uses it.

OK, I will take a look at source code about Ext.data.Connection, thank you
