Answer 1

You need to loop over your first array, and inside this loop, loop again inside the filter.

If userid and projectid are equals, you can add the row to your filtered array:

myArray = [{
    userid: "100",
    projectid: "10",
    rowid: "0"
}, {
    userid: "101",
    projectid: "11",
    rowid: "1"
}, {
    userid: "102",
    projectid: "12",
    rowid: "2"
}, {
    userid: "103",
    projectid: "13",
    rowid: "3"
}, {
    userid: "101",
    projectid: "10",
    rowid: "4"
}];
myFilter = [{
    userid: "101",
    projectid: "11"
}, {
    userid: "102",
    projectid: "12"
}, {
    userid: "103",
    projectid: "11"
}];

function filterArray(array, filter) {
    var myArrayFiltered = [];
    for (var i = 0; i < array.length; i++) {
        for (var j = 0; j < filter.length; j++) {
            if (array[i].userid === filter[j].userid && array[i].projectid === filter[j].projectid) {
                myArrayFiltered.push(array[i]);
            }
        }
    }
    return myArrayFiltered;
}
myArrayFiltered = filterArray(myArray, myFilter);
console.log(myArrayFiltered);
