Sending json array as querystring in senchatouch2 - arrays

Question

Should we send json array or normal array as querystring in senchatouch2

Answer 1

in any case you can only send String in URL so if you have JSON then use Ext.JSON.encode to make it string and if you have JS Array use toString or join method to flatten the array before appending it to URL.
Since you said querystring so I suppose you and not doing POST request.
[EDIT]
Looking at your comment it seems you want to send some data to service for creation but in that case you should not send data as querystring, you should send it in message body. Following is example to send JSON data to your service:
var obj = new Object();
obj.loginEntry = new Object();
obj.loginEntry.userid = username;
obj.loginEntry.password = password;
var data = Ext.JSON.encode(obj);
Ext.Ajax.request({
url : 'http://myserver:port/service/entity',
method : "POST",
headers: {
/* Important because default is
* Content-Type:application/x-www-form-urlencoded; charset=UTF-8
* which is not supported by service
*/
'Content-Type': 'application/json'
},
params : data,
success : function(response) {
},
failure : function(response) {
}
}
);

While we use POST method to send parameters in Sencha Touch2 use jsonData in Ajax Request like,
Ext.Ajax.request({
url:'',
method:'POST',
disableCaching:false,
headers: {
'Accept':'application/json',
'Content-Type':'application/json'
},
jsonData: {
FirstName:fname //{"FirstName":["Sam","paul"]}
},
success: function(response)
{
console.log(response.responseText);
},
failure: function(response)
{
console.log(response.responseText);
},
});
