从AJAX中的JSON中删除“未定义”值

Question

I have a form that submits data to a GoogleSheet as JSON via AJAX. 我有一个表单，可以通过AJAX将数据作为JSON提交到GoogleSheet。

I want to change it so that blank fields show as just empty rather than showing as undefined in the GoogleSheet. 我想更改它，以使空白字段显示为空而不是在GoogleSheet中显示为undefined 。

Below is my code: 下面是我的代码：

HTML Form: HTML表单：

                $('#bookingForm').submit();

I have tried using beforeSend but this does not seem to have any effect. 我试过使用beforeSend但这似乎没有任何效果。

Assuming there are no nested objects in your form, you can simply loop on your object elements before sending them 假设表单中没有嵌套的对象，则可以在发送对象元素之前先对其进行循环

let jsObj = $form.serializeObject();

Object.keys(jsObj).forEach(key => {
  jsObj[key] = jsObj[key] ? jsObj[key] : "";
})

Then you'll just have to send that object via AJAX : 然后，您只需要通过AJAX发送该对象：

$('#submit-form').on('click', function(e) {
var valid = this.form.checkValidity();
if (valid) {
    e.preventDefault();
    var jqxhr = $.ajax({
        url: url,
        method: "GET",
        dataType: "json",
        dataType: "json",
        data: jsObj,
        beforeSend: function (key,value) {
            return (value == undefined) ? "" : value
        },
        success: function () {
            $('#redirect_page').modal('show');
            $('#bookingForm').submit();
        }
    });
  }
});
