使用模态表单和显示更新的详细信息在数组中更新对象

Question

我正在尝试通过单击"编辑"按钮来更新外部对象。它提出了一个弹出窗口，其中我可以输入新信息，然后应该相应地更新用户。但是某种程度上似乎不起作用。它只是触发了一个页面刷新，根本什么也不会发生。您能帮我解决这个问题吗？

var myData = [{
    company: "ABC",
    url: "www.abc.com",
    type: "internal"
  }, {
    company: "CDE",
    url: "www.cde.com",
    type: "internal"
  }, {
    company: "DEF",
    url: "www.def.com",
    type: "external"
  }, {
    company: "EFG",
    url: "www.efg.com",
    type: "internal"
  }, {
    company: "FGH",
    url: "www.fgh.com",
    type: "external"
  }];
  $('#createData').click(function() {
    createDisplay();
  });
function createDisplay() {
  myData.forEach(function(obj) {
  $('.container').append(
    $('<div>').addClass('box').append(
    $('<label>').text('Company Website: '),
    $('<a>').addClass('compUrl').attr('href', obj.url).text(obj.company),
    obj.type == 'external' ? $('<br /><button>').addClass('edit-btn').text('Edit').attr({"data-toggle":"modal", "data-target":"#updateData"}) : ''
    )
  )
  });
}
$(document).on('click', '.edit-btn', function(){
 var index = getIndex(this);
  $("#updateForm").submit(function(index){
      updateData(index);
    return false;
  });
});
function getIndex(item){
  return $(item).parents('.box').index();
}
function updateData(obj) {
  companyName = $('#companyName').val();
  companyUrl = $('#companyUrl').val();
  var upObj = {
    company: companyName,
    url: companyUrl,
    type: "external"
  }
  myData.splice(index, 1, upObj);
  createDisplay();
}

.box {
  height: 100px;
  background-color: skyblue;
  border: 1px solid black;
  margin-top: 5px;

好吧，我发现了问题。这是我正在使用的变量索引。我相信尝试提交表格，这是造成问题的。

var myData = [{
  company: "ABC",
  url: "www.abc.com",
  type: "internal"
}, {
  company: "CDE",
  url: "www.cde.com",
  type: "internal"
}, {
  company: "DEF",
  url: "www.def.com",
  type: "external"
}, {
  company: "EFG",
  url: "www.efg.com",
  type: "internal"
}, {
  company: "FGH",
  url: "www.fgh.com",
  type: "external"
}];
$('#createData').click(function() {
  createDisplay();
});
function createDisplay() {
  $('.container').empty();
  myData.forEach(function(obj) {
  $('.container').append(
    $('<div>').addClass('box').append(
    $('<label>').text('Company Website: '),
    $('<a>').addClass('compUrl').attr('href', obj.url).text(obj.company),
    obj.type == 'external' ? $('<br /><button>').addClass('edit-btn').text('Edit').attr({'data-toggle':'modal', 'data-target':'#updateData'}) : ''
    )
  )
  });
}
var currentIndex;
$(document).on('click', '.edit-btn', function(){
  currentIndex = $(this).parents('.box').index();
});
$('#updateForm').submit(function(){
  updateData(currentIndex);
  return false;
});
function updateData(index) {
  companyName = $('#companyName').val();
  companyUrl = $('#companyUrl').val();
  var upObj = {
  company: companyName,
  url: companyUrl,
  type: 'external'
  }
  myData.splice(index, 1, upObj);
  createDisplay();
}

.box {
