store Extjs and array

[fvinson]

I work with MVC
I have a model and a store

Ext.define('MetExplore.model.Annotation', {
        extend: 'Ext.data.Model',
        fields: [{name:'id',type:'string'},
        		 {name:'table',type:'string'},
        		 {name:'field',type:'string'},
        		 {name:'name',type:'string'},
        		 {name:'dbIdentifier',type:'string'},
        		 {name:'oldV',type:'string'},
        		 {name:'newV',type:'string'}
        		]
    });
Ext.define('MetExplore.store.S_Annotation',{
		extend : 'Ext.data.ArrayStore',
        model: 'MetExplore.model.Annotation',
        id: 'annotation'
    });

In controller, i add data in the store when the user change

.....
init: function() {
		this.control(
			{'gridReaction': {
				edit:this.editChange},
			'gridReaction button[action=ReactionChange]':{click:this.ReactionChange},


...	
 editChange: function(editor,e){	
    	//il faudra verifier qu'il n'y a pas deja cet enregistrement dans tableau   	
    	var oldV= e.originalValue;
    	var newV= e.value;
    	if (oldV != newV) {
    		//ajout dans tableau : id/ field / oldValue / NewValue
    		var annot= Ext.getStore('S_Annotation');
    		annot.add({'id':e.record.get('id'),'table':'Reaction','field':e.field,'name':e.record.get('name'),'dbIdentifier':e.record.get('dbIdentifier'),'oldV':oldV,'newV':newV});
    	};
...

this is ok
when the user click on button 'ReactionChange' , i want to send the data to php file in json format like this :
[{'id':10,'table':'Reaction','field':name',.....},
{'id':....

In my code i send an Extjs object and i can't read it in php ; i want just the array with the data and not constructor,.....

			buttons : [ {
				text : 'Submit',
				handler : 
					function(widget, event) {
						var annot= Ext.getStore('S_Annotation');
					   	//var jsonModif= Ext.encode(annot);
					   	var jsonModif= annot.getRange();
					   	console.log(jsonModif);
					   	Ext.Ajax.request({
					   		url:'lib/php/changereaction_v1.php',
					   		params: {Reactions:jsonModif},//,idUser:idUser}

How can i make this
Thank you

You may want to look at http://docs.sencha.com/ext-js/4-0/#!...ta.writer.Json. They have a good example of how it ties into a store at http://dev.sencha.com/deploy/ext-3.4...ful/restful.js.
