Removing items from store without using filter

Question

I am trying to remove the fields from accordion list, if its not match with my searchfield name only actual search name should be shown in list. Search functionality working fine. But i cant remove rest of elements from the store. Duplicate occurs

 for (var j = length; j--;)
    {
    console.log(store.data.items[j]);
    console.log(store.data.items[j].data.testname);
    //store.clearFilter(true);
       if (store.data.items[j].data.testname.search(new RegExp(searchfield, "i")) === -1) 
       {
        //store.filter('testname',store.data.items[j].data.testname);
          store.data.items[j].remove();
        }
    }

Output - Type Mango

• Mango
• Apple --> Unwanted
• Banana --> Unwanted
• Mango --> Duplicate

Expected

• Mango ---> Actual search

Or

• Mango
• Apple
• Banana

Any suggestion.

Answer 1

store.removeAt(j);

You want to remove a record and not only the data. But if you want to remove it only for some time you might want to use

store.filterBy(function() {
    your Code
    return true only for those you need and false for those unwanted ones
})
