How to retrieve JSON Data Array from ExtJS Store
Is there a method allowing me to return my stored data in an ExtJS Grid Panel exactly the way I loaded it using:
var data = ["value1", "value2"]
Store.loadData(data);
I would like to have a user option to reload the Grid, but changes to the store need to be taken into account. The user can make changes and the grid is dynamically updated, but if I reload the grid, the data that was originally loaded is shown even though the database has been updated with the new changes. I would prefer not to reload the page and just let them reload the grid data itself with the newly changed store.
I guess I'm looking for something like this:
var data = Store.getData();
//data = ["value1", "value2"]
after its all said and done. Or is there a different way to refresh the grid with new data that I am not aware of. Even using the proxy still uses the "original" data, not the new store.
Answer
Store.getRange() seems to be exactly what you are searching for. It will return you Ext.data.Record[] - array of records. If no arguments is passed, all the records are returned.
