I dont add a records to the store ExtJS

ExtJs 6.2 

    var store = Ext.create("Ext.data.Store"); 

    var dep = {dd:11};

    store.add({dd:11});
    store.add(dep);
    store.add(dep);
    store.add(dep); 
    store.add(dep);
    store.add(dep);
    store.add(dep);
    store.add(dep);
    store.add({dd:11});
    console.log("Count:" + store.count());

Count:3

A variable object is added only once. Why?????

Solution

  • The reason behind this is that store.add is not pure function meaning it changes dep so after first add dep no longer holds reference to a simple javascript object but instead it is a reference to added model. After that you are trying to add model that is already in a store so it is omitting it

    You can verify this by doing console.log of a def variable after first add

    Wokaround:

    store.add(Ext.clone(dep));
