Splice or Remove list of elements from JSON Array

Question

I am having a JSON Array Output from REST API like this , I am displaying this items on the HTML using ng-repeat.

var searchresponse = [{
    "items": [{
        "employeeId": "ABC",
        "type": "D",
        "alive": "Yes"

    }, {
        "employeeId": "DEF",
        "type": "D",
        "alive": "Yes"

    }, {
        "employeeId": "NPK",
        "type": "D",
        "alive": "Yes"

    }, {
        "employeeId": "PKN",
        "type": "A",
        "alive": "Yes"
    }],
    "more": false
}];

when user tries to delete using selectall/single select i am calling a REST API to remove the employee id from the db . once i get a successful response i am planning to splice / remove the values that have been selected by the user from the VIEW. I would like to remove the following employeeid and their type,alive removed from the searchresponse

 var data1=["ABC","NPK"];

Whatever the data1 has corresponding details should be removed from the searchresponse

All you need is to eliminate each item from items array whose employeeId is in data1,using splice method.

        "type": "D",

        "employeeId": "DEF",
        "type": "D",
        "alive": "Yes"

    }, {
        "employeeId": "NPK",
        "type": "D",
        "alive": "Yes"

    }, {
        "employeeId": "PKN",
        "type": "A",
        "alive": "Yes"
    }],
    "more": false
}];
var data1=["ABC","DEF"];
var items=searchresponse[0].items;
var i=items.length;
while (i--) {
    if(data1.indexOf(items[i].employeeId)!=-1){
        items.splice(i,1);
    }
}
console.log(searchresponse[0].items);

I tried this and its not entering inside the for loop . Am i missing anything – Praveen Dec 13 '16 at 20:37
Probably `searchresponse[0].items` has length 0. – Mihai Alexandru-Ionut Dec 13 '16 at 20:42
Are you sure that `searchresponse` looks like in your post ? – Mihai Alexandru-Ionut Dec 13 '16 at 20:44
This is what console.log printed Array[1] 0:Object $$hashKey:"object:16" employeeId:"ABC" alive:"YES" type:"D" selected:false – Praveen Dec 13 '16 at 20:58
It worked !! I was setting the items value directly in scoperesponse . so i assigned items to scoperesponse and it worked . thanks a lot – Praveen Dec 13 '16 at 21:15
@ Alexandru-Ionut Mihai - For some reason when i select multiple items , last item is not getting removed . Do you know why ? – Praveen Dec 16 '16 at 02:48
It is Removing only even number of elements like 0,2,4 . Leaving out 1,3 etc!! – Praveen Dec 16 '16 at 04:07
