Get value of each TextBox inside GrideView and save value in array using jQuery in ASP.Net

There is a Grideview that user can add or remove rows.

Each rows have textbox and dropdown list. now, I want read each row ang get textbox and dropdown value.

I wrote below code:

var ResultArray = [];
$("#grdLayerInfo tr").each(function () {
      var field = $(this).find("td input[id*=txtFiled]").val();
      var value = $(this).find('td option:selected').val();
      ResultArray.push(field, value);
        });
    alert(ResultArray);

result is:

,,name,String,age,Numeric,,

but I want result like this:

name,String,age,Numeric

What is wrong?
