Question

我对下面代码的问题是，当我点击表格中的任何按钮（完全使用javascript生成）时，DivNumberString值始终为5_5。对此为何发生的任何见解？

<!DOCTYPE HTML>
<html>
<body>
  <div id="TableForCountries" class="TableForCountries">
  </div>
  <script>
    function AddTable() {
        var TableDiv = document.getElementById("TableForCountries");
        var Table = document.createElement("table");
        Table.border = 1;
        TableDiv.appendChild(Table);

        var i, j;
        var NumCountries = 5;
        var NumSectors = 5;

        for (i = 0; i < NumCountries; i++) {
          var CurrentRow = Table.insertRow(i);
          for (j = 0; j < NumSectors + 1; j++) {
            var Cell = CurrentRow.insertCell(j);
            var SectorString = String(i + 1) + "_" + String(j);

            if (j == 0) {
              var CountryData = document.createElement("div");
              CountryData.id = SectorString;
              var AddOrDelete = "add";
              var CountryDataSelect = document.createElement("select");
              var AddButton = document.createElement("button");

              AddButton.onclick = function() {
                AddOrDeleteDiv("add", SectorString);
              };

              CountryData.appendChild(CountryDataSelect);
              CountryData.appendChild(AddButton);

              Cell.appendChild(CountryData);
            } else if (j == NumSectors) {

              var CountryData = document.createElement("div");
              var CountryDataSelect = document.createElement("select");
              CountryData.id = SectorString;
              var AddOrDelete = "add";

              var DeleteButton = document.createElement("button");
              DeleteButton.onclick = function() {
                AddOrDeleteDiv("delete", SectorString);
              };
              CountryData.appendChild(CountryDataSelect);

              CountryData.appendChild(DeleteButton);
              Cell.appendChild(CountryData);
            } else {
              var CountryData = document.createElement("div");
              var CountryDataSelect = document.createElement("select");
              var AddButton = document.createElement("button");

              AddButton.onclick = function() {
                AddOrDeleteDiv("add", SectorString);
              };
              var DeleteButton = document.createElement("button");

              DeleteButton.onclick = function() {

              };
              CountryData.appendChild(CountryDataSelect);
              CountryData.appendChild(AddButton);
              CountryData.appendChild(DeleteButton);
              Cell.appendChild(CountryData);
            }
          } //End of inner for    
        } //End of outer for     
      } //end of function


    function AddOrDeleteDiv(AddOrDelete, DivNumberString) {
      console.log(DivNumberString);
      var CountryNumber = parseInt(DivNumberString.charAt(0));
      var SectorNumber = parseInt(DivNumberString.charAt(2));

      if (AddOrDelete == "add") {
        document.getElementById(CountryNumber + "_" + String(SectorNumber + 1)).style.display = "inline";
      } else {
        document.getElementById(CountryNumber + "_" + SectorNumber).style.display = "none";
      }
    }

    AddTable();
  </script>
</body>
