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;
}
}
答案 0 :(得分：0)
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。
正如James在评论中指出的那样，您需要questions.value == ''而不是questions == ''
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
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

一些注意事项：
使用更具选择性的选择器将是一种更具体的方法。
