i know it's a question asked many times here, but i tried all the solutions and no one is working. I want to change the output in my CRUD from the input form to dd/mm/yyyy and not in yyyy-mm-dd.
Here's my code:
var nextId = 1;
var activeId = 0;
function productDisplay(ctl) {
  var row = $(ctl).parents("tr");
  var cols = row.children("td");
  activeId = $($(cols[0]).children("button")[0]).data("id");
  $("#productname").val($(cols[1]).text());
  $("#introdate").val($(cols[2]).text());
  $("#finishdate").val($(cols[3]).text());
  $("#url").val($(cols[4]).text());
  $("#phone").val($(cols[5]).text());
  $("#note").val($(cols[6]).text());
  $("#client").val($(cols[7]).text());
  $("#updateButton").text("Aggiorna");
}
function productUpdate() {
  if ($("#updateButton").text() == "Add") {
    productUpdateInTable(activeId);
  }
  else {
    productAddToTable();
  }
  formClear();
  $("#productname").focus();
}
function productAddToTable() {
  if ($("#productTable tbody").length == 0) {
    $("#productTable").append("<tbody></tbody>");
  }
  $("#productTable tbody").append(
    productBuildTableRow(nextId));
  nextId += 1;
}
function productUpdateInTable(id) {
  var row = $("#productTable button[data-id='" + id + "']")
    .parents("tr")[0];
  $(row).after(productBuildTableRow(id));
  $(row).remove();
  formClear();
  $("#updateButton").text("Add");
}
function productBuildTableRow(id) {
  var ret =
    "<tr>" +
    "<td>" +
    "<button type='button' " +
    "onclick='productDisplay(this);' " +
    "class='btn btn-default' " +
    "data-id='" + id + "'>" +
    "<span class='glyphicon glyphicon-pencil' />" +
    "</button>" +
    "</td>" +
    "<td>" + $("#productname").val() + "</td>" +
    "<td>" + $("#introdate").val() + "</td>" +
    "<td>" + $("#finishdate").val() + "</td>" +
    "<td>" + $("#url").val() + "</td>" +
    "<td>" + $("#phone").val() + "</td>" +
    "<td>" + $("#note").val() + "</td>" +
    "<td>" + $("#client").val() + "</td>" +
    "<td>" +
    "<button type='button' " +
    "onclick='productDelete(this);' " +
    "class='btn btn-default' " +
    "data-id='" + id + "'>" +
    "<span class='glyphicon glyphicon-minus' />" +
    "</button>" +
    "</td>" +
    "</tr>"
  return ret;
}
function productDelete(ctl) {
  var result = confirm("Want to delete record?");
  if (result) {
    var result2 = confirm("Really?");
  }
  if (result2) {
    $(ctl).parents("tr").remove();
  }
}
function formClear() {
  $("#productname").val("");
  $("#introdate").val("");
  $("#finishdate").val("");
  $("#url").val("");
  $("#phone").val("");
  $("#note").val("");
  $("#client").val("");
}
function doSearch(text, color = "yellow") {
  if (color != "transparent") {
    doSearch(document.getElementById('hid_search').value, "transparent");
    document.getElementById('hid_search').value = text;
  }
  if (window.find && window.getSelection) {
    document.designMode = "on";
    var sel = window.getSelection();
    sel.collapse(document.body, 0);
    while (window.find(text)) {
      document.execCommand("HiliteColor", false, color);
      sel.collapseToEnd();
    }
    document.designMode = "off";
  } else if (document.body.createTextRange) {
    var textRange = document.body.createTextRange();
    while (textRange.findText(text)) {
      textRange.execCommand("BackColor", false, color);
      textRange.collapse(false);
    }
  }

</div>When I insert a new record from form field date, the output in my CRUD is like YYYY-MM-DD.
