force extjs.data.store to use POST(or GET) only

By default extjs.data.store will use 'POST' when you pass any parameters, otherwise, it will use 'GET'. For example:

//use 'GET'

{

xtype : 'jsonstore',

url     :  'list.php'

}

//use 'POST'

{

xtype : 'jsonstore',

url     : 'getArticle.php',

params : {user_id : 1}

}

In case we want to always use one method without worrying about parameters, we have to specify the proxy:

//always use 'POST'

{

xtype : 'jsonstore',

proxy : new Ext.data.HttpProxy({url:'list.php', method:'POST'})

}

To use 'GET' only, just change the method to 'GET'.
