Is a JSON writer what I need?

[chrisminniti]

I am working on an app that interfaces with a SharePoint list. Currently I am able to write to the list, using a jQuery $.ajax method, which I don't want to do, because I know there is a way to do the same thing using Sencha Touch. Here is my working code.

xtype: 'button',                    
text: 'Submit',
handler: function() {

                            var TextToSubmit = JSON.stringify(Ext.getCmp('SubmitATopicFormPanel').getValues(), null, 2);
                            alert(TextToSubmit);

                            $.ajax({
                                  type: "POST",
                                  url: "myURL",
                                  data: TextToSubmit,
                                  contentType: "application/json; charset=utf-8",
                                  error: function(xhr) {
                                    alert(xhr.status + ':' + xhr.statusText);                                    
                                    }
                            });


                            }
                    }

This is a submit button, that when fired, grabs my form values, puts it in JSON format, and sends it to the server using and jQuery ajax 'post' method. So my question is do I call a JSON writer in my store, or is there a better way. Below is my store. I have the JSON writer, but i'm not currently using it.

Ext.define('TopicApp.store.SafetyStore', {            
            extend: 'Ext.data.Store',
            id: 'SafetyStore',
            config: {
                autoLoad: true,
                model: 'TopicApp.model.SafetyModel',
                proxy: {
                    type: 'ajax',
                    url: "myURL",
                    reader: {
                        type: 'xml',             
                       record: 'properties'
                    },
                    writer: {
                        type: 'json'
                    }
                }
            }
});

If you are editing records in a store then the writer can be used. If you are just wanting to send some parameters to the server then you can use Ext.Ajax.request then.

for others,

xtype: 'button',                    
text: 'Submit',
handler: function() {

var form = Ext.getCmp('SubmitATopicFormPanel');
var TextToSubmit = JSON.stringify(Ext.getCmp('SubmitATopicFormPanel').getValues(), null, 2);

      Ext.Ajax.request({
            url: "myURL",
            method: 'POST',
            headers: {
                   "Content-Type": "application/json"
            },
                  params: TextToSubmit,
                  success: function (response){
                         Ext.Msg.alert('Success', 'Your Topic Has Been Submitted!');
                         Ext.getCmp('MainPanel').animateActiveItem(0, {type:'slide', direction: 'right'});
                         form.reset();
                                },

                         failure: function () {
                              Ext.Msg.alert('Error', 'Error');
                         }
                });
}
