var request = Ext.Ajax.request({
url: 'MCApp',
jsonData: searchquery,
params: {
start: 0,
limit: itemsPerPage
},
success: function(response) {
mainresponse = response.responseText;
if (mainresponse.length == 0) {
alert('No results returned');
return;
}
var decoded = Ext.decode(mainresponse);
for (var i = 0; i < decoded.elements.length; i++) { // loop over decoded data
var element = decoded.elements[i].element;
var model = {};
for (var x = 0; x < element.attributes.length; x++) { // loop over attributes
var attribute = element.attributes[x];
model[attribute.attrname] = attribute.attrvalue; // mapping element names & attributes
}
newstore.add(model); // implicitly cast data as Model
models[i] = model;
}
newstore.loadRawData(models);
},
failure: function() {
alert('Search Failed: Could not reach the server')
}
});
我现在已经重新创建了我
request
中的store
babove。我需要做的是添加这些成功和失败功能。
var store = Ext.create('Ext.data.Store', {
storeId: 'resultsetstore',
autoLoad: false,
pageSize: itemsPerPage,
fields: [
{ name: 'id', type: 'auto' },
{ name: 'name', type: 'auto' },
{ name: 'description', type: 'auto' }
],
proxy: {
type: 'ajaxwithpayload', //customized proxy to read "jsonData"
url: 'MCApp',
jsonData: searchquery,
reader: {
type: 'json',
root: 'elements'
}
success: { /* success functions */ },
failure: { /* failure functions */ }
}
});
我的反应是:
{
"elements":[
{
"element":{
"name":"Element Name",
"id":"Element ID",
"attributes":[
{
"attrname":"id",
"attrvalue":"This is the ID"
},
{
"attrname":"name",
"attrvalue":"This is the name"
},
//etc.
1)有什么办法可以在我的商店中重新创建这些功能?
2)是将我的响应解码是将我的响应加载到商店中的最佳方法吗?
eDit
我加载商店时使用回调函数:
store.load({
params: { start: 0, limit: itemsPerPage },
callback: function(options, success, response, records) {
if (success) {
alert(response.responseText);
}
}
});
,无论如何,我的警报中得到了一个,它告诉我加载了0个记录。但是,当我在Firebug中查看我的回应时,我看到我的JSON字符串很好地回来了。
在商店中处理
您可以在代理上聆听
Exception-Event捕获所有商店错误。 为了在商店中的成功载荷 - 事件
undefined
var store = Ext.create('Ext.data.Store', {
storeId: 'resultsetstore',
autoLoad: false,
pageSize: itemsPerPage,
fields: [
{ name: 'id', type: 'auto' },
{ name: 'name', type: 'auto' },
{ name: 'description', type: 'auto' }
],
listeners: {
load: function(store, records, successful, eOpts) {
if (successfull) {
alert('success');
}
}
},
proxy: {
type: 'ajaxwithpayload', //customized proxy to read "jsonData"
url: 'MCApp',
jsonData: searchquery,
reader: {
type: 'json',
root: 'elements'
},
listeners: {
exception: function(proxy, response, operation, eOpts) {
alert('exception');
}
}
}
});
或使用Sync(用于删除,修改,...)
store.load({
callback: function(records, operation, success) {
// ...
}
});
