我首先为我的英语道歉，我用谷歌翻译。
我使用联系人表单7，通过其他设置，我希望填写表单后的用户能够访问同一页中包含的div。
各种div通过filterselection被隐藏和激活，我使用这个简单的命令来打开例如id为“mydiv”的div：

<button onclick = "filterSelection ('mydiv')">

这是我用于筛选选择的代码

<script>
filterSelection ("dashboard")
function filterSelection (c) {
  var x, i;
  x = document.getElementsByClassName ("filterDiv");
  if (c == "all") c = "dashboard";
  for (i = 0; i <x.length; i ++) {
    w3RemoveClass (x [i], "show");
    if (x [i] .className.indexOf (c)> -1) w3AddClass (x [i], "show");
  }
}

function w3AddClass (element, name) {
  var i, arr1, arr2;
  arr1 = element.className.split ("");
  arr2 = name.split ("");
  for (i = 0; i <arr2.length; i ++) {
    if (arr1.indexOf (arr2 [i]) == -1) {element.className + = "" + arr2 [i];}
  }
}

function w3RemoveClass (element, name) {
  var i, arr1, arr2;
  arr1 = element.className.split ("");
  arr2 = name.split ("");
  for (i = 0; i <arr2.length; i ++) {
    while (arr1.indexOf (arr2 [i])> -1) {
      arr1.splice (arr1.indexOf (arr2 [i]), 1);
    }
  }
  element.className = arr1.join ("");
}

// Add active class to the current button (highlight it)
var btnContainer = document.getElementById ("myBtnContainer");
var btns = btnContainer.getElementsByClassName ("btn");
for (var i = 0; i <btns.length; i ++) {
  btns [i] .addEventListener ("click", function () {
    var current = document.getElementsByClassName ("active");
    current [0] .className = current [0] .className.replace ("active", "");
    this.className + = "active";
  });
}
</script>

联系人表单7现在允许您通过以下代码段设置其他设置：

document.addEventListener ('wpcf7submit', function (event) {
  alert ("Fire!");
}, false);

有人能帮我写正确的代码来打开，例如id为“mydiv”的div，在填写表格并按下inva键之后，为什么我会发疯？
