var aryExample = ["ID:2","ID:3","ID:4"], aryNew = [];
for( var i in aryExample ) {
  aryNew.push({ID:Number(aryExample[i].split(":")[1])});
}
console.dir(aryNew);

That should do it.

For getting an array with objects, you could split the strings and build a new object with the wanted property and the numerical value.

var data = ["ID:2","ID:3","ID:4"],
    result = data.map(function (s) {
        var p = s.split(':'),
            t = {};
        t[p[0]] = +p[1];
        return t;
    });
    
console.log(result);

var newArrayOfObjs =arr.map((item)=> {
 var obj = {};
 var splitItems = item.split(':');
 obj[splitItems[0]] = splitItems[1];
 return obj;
}

You'll have to split the string on ':' and set the 0th element as key and 1st element as value.
