检查是否填写了所有表单字段 - 不起作用

Question

我在Google代码管理器上有一个事件，应该在成功提交表单时触发。表单是Cognito Forms的嵌入代码。该页面托管在squarespace中。使用Google跟踪代码管理器预览我可以看到提交后满足所有条件，但下面的功能除外，这应该是＆＃34; true＆＃34;成功提交，但由于某种原因即使我成功提交表格也是假的。

可能出现什么问题？ This is联系我们表格和功能下方。非常感谢。

function areAllFieldsFilled(){
  var requiredFields = document.getElementsByClassName('cognito')[0].getElementsByTagName('form')[0].getElementsByTagName('input');
  var questions = document.getElementsByClassName('cognito')[0].getElementsByTagName('form')[0].getElementsByTagName('textarea')[0];
  var check = 0;

  if (questions == '') {
    check++;
  } else{
    for (var i = 0; i < 3; i++) {
      if (requiredFields[i].value == '') {
        check++;
        break;
      }
    }
  }
  if (check == 0) {
    return true;
  } else {
    return false;
  }
}

我检查了您的表单，看起来有两个原因导致您为填写的表单返回false。

1. 正如James在评论中指出的那样，您需要questions.value == ''而不是questions == ''

2. 您可能没有注意到的表单中有一个隐藏的<input />标记。该输入的值始终为空字符串，因为它没有值。要快速修复此问题，您可以在1开始循环。 Side Note ：循环的长度应为requiredFields.length -1（因为我们现在从1开始而不是0）而不是硬编码3

这是一个工作示例

＆＃13;
＆＃13;
document.addEventListener("DOMContentLoaded", function(event) {
  document.getElementById("c-submit-button").addEventListener("click", areAllFieldsFilled);
});

function areAllFieldsFilled(event) {
  event.preventDefault(); // For testing, REMOVE THIS
  var requiredFields = document.getElementsByTagName('form')[0].getElementsByTagName('input');
  var questions = document.getElementsByTagName('form')[0].getElementsByTagName('textarea')[0];
  var check = 0;
  if (questions.value == '') {
    console.log("questions was empty");
    check++;
  } else {
    for (var i = 1; i < requiredFields.length - 1; i++) {
      if (requiredFields[i].value == '') {
        check++;
        break;
      }
    }
  }
  console.log(`check count is ${check}`);
  if (check == 0) {
    console.log("Returning True");
    return true;
  } else {
    console.log("Returning False");
    return false;
  }
  // or replace the above 7 lines with return check == 0
}
