Saving data entered in extJS textbox - extjs

Question

I have made textboxes in ExtJS through which I will be taking input for an ID and a name. I want to use these values(ID and name) in some other classes. So, I want to save these values somewhere(preferably in a string) so that they can be used later.
Please can someone advise me on how to do that.
function textBoxTab() {
var simple = new Ext.FormPanel({
labelWidth: 75,
frame: true,
title: 'TAB_DIM',
bodyStyle: 'padding:5px 5px 0',
width: 350,
defaults: {
width: 230
},
defaultType: 'textfield',
items: [{
xtype: 'textfield',
name: 'Module_id',
fieldLabel: 'Module_id',
allowBlank: false // requires a non-empty value
}, {
xtype: 'textfield',
name: 'Module_desc',
fieldLabel: 'Module_desc',
allowBlank: false // requires a non-empty value
}],
buttons: [{
text: 'Cancel',
handler: function() {
this.up('form').getForm().reset();
}
}, {
text: 'Submit',
handler: function() {
var form = this.up('form').getForm();
form.submit({
clientValidation: true,
url: 'save.txt',
success: function() {
Ext.Msg.alert('saved');
},
failure: function(form, action) {}
});
if (form.isValid()) {
//Ext.Msg.alert('Submitted Values', form.getValues(true));
this.up('form').getForm().submit();
}
}
}]
});
simple.render(document.body);
}
I have tried this "url:'save.txt" thing but it is not working.
Please help, thanks in advance.

The best way is to store them in a model, and have a controller manage your views and models.
There is several guide on how to architect your ExtJS application using MVC (model-view-controller) :

http://docs.sencha.com/extjs/4.2.1/#!/guide/mvc_pt2
http://docs.sencha.com/extjs/4.2.1/#!/guide/mvc_pt3
