Question

How to remove item from jquery array object.

I used splice method as follows. But it slice next item of array[i].

    $.each(array, function (i, item) {
    var user = array[i];
    jQuery.each(array2, function (index, idata) {
        debugger
        if (idata.Id == user.UserId) {
            tempFlag = 1;
            return false; // this stops the each
        }
        else {
            tempFlag = 0;
        }
    });

    if (tempFlag != 1) {
     //removes an item here

        array.splice(user, 1);
    }
})

Can anyone tell me where i am wrong here?

Answer 1

You are using the value in user as index, i.e. array[i], instead of the value i.

$.each(array, function (i, item) {
  var user = array[i];
  jQuery.each(array2, function (index, idata) {
    debugger
    if (idata.Id == user.UserId) {
      tempFlag = 1;
      return false; // this stops the each
    } else {
      tempFlag = 0;
    }
  });

  if (tempFlag != 1) {
    //removes an item here
    array.splice(i, 1);
  }
});

You may get problems from removing items from the array that you are currently looping, though…
