    Default Delete an item in a list permanently from JSON file

    Hello ,

    i am trying to delete an item list when the user taps on a delete button.

    i delete the item from the store and the item is successfully deleted from the list , However, when i re-run the application all the items are present .

    in order to delete the items permanently i tend to think that i must delete the item in the JSON file , how can i obtain the JSON string of the list and modify it.

    i am using the following code for deleting the item :

    Code:
    var store = Ext.getStore('VideoList');             store.removeAt(index);
                 store.sync();
                 this.getList().refresh();

    I appreciate your help

    Are you loading from a .json file? If so then you need to send a request to a server side script to edit the .json file as JavaScript cannot do this.
