如何使用Reactjs更新Google Spreadsheets中的特定行？

Question

需要發生的是，在我的React Web應用程序中有此表單，輸入的數據應發送到Google Spreadsheet。

1. 在電子表格中插入新數據時，有沒有避免使用時間戳的方法？
2. 如何更新特定行？ 例如，我有喬，我需要將他的電話號碼更新為456

| NAME  |  NUMBER | 
|-------|---------|
|Joe    |123      |
|Brian  |420      |
|Raine  |143      |

如何通過網絡應用程序執行此操作？

我已經嘗試過了但是還是沒有運氣

這是來自Web應用程序，在componentDidMount()有一些代碼

此代碼用於表單數據，並防止頁面重定向到App腳本鏈接。 基本上，它停留在頁面上，甚至重新加載表單。

    componentDidMount() {

        console.log("Contact form submission handler loaded successfully.");
        // bind to the submit event of our form
        var forms = document.querySelectorAll("form.gform");
        for (var i = 0; i < forms.length; i++) {
            forms[i].addEventListener("submit", handleFormSubmit, false);
        }


        //document.addEventListener("DOMContentLoaded", loaded, false);

        function validateHuman(honeypot) {
            if (honeypot) {  //if hidden form filled up
                console.log("Robot Detected!");
                return true;
            } else {
                console.log("Welcome Human!");
            }
        }

        // get all data in form and return object
        function getFormData(form) {
            var elements = form.elements;
            var honeypot;

            var fields = Object.keys(elements).filter(function (k) {
                if (elements[k].name === "honeypot") {
                    honeypot = elements[k].value;
                    return false;
                }
                return true;
            }).map(function (k) {
                if (elements[k].name !== undefined) {
                    return elements[k].name;
                    // special case for Edge's html collection
                } else if (elements[k].length > 0) {
                    return elements[k].item(0).name;
                }
            }).filter(function (item, pos, self) {
                return self.indexOf(item) === pos && item;
            });

            var formData = {};
            fields.forEach(function (name) {
                var element = elements[name];

                // singular form elements just have one value
                formData[name] = element.value;

                // when our element has multiple items, get their values
                if (element.length) {
                    var data = [];
                    for (var i = 0; i < element.length; i++) {
                        var item = element.item(i);
                        if (item.checked || item.selected) {
                            data.push(item.value);
                        }
                    }
                    formData[name] = data.join(', ');
                }
            });

            // add form-specific values into the data
            formData.formDataNameOrder = JSON.stringify(fields);
            formData.formGoogleSheetName = form.dataset.sheet || "responses"; // default sheet name
            //formData.formGoogleSend = form.dataset.email || ""; // no email by default

            console.log(formData);
            return { data: formData, honeypot };
        }

        function handleFormSubmit(event) {  // handles form submit without any jquery
            event.preventDefault();           // we are submitting via xhr below
            var form = event.target;
            var formData = getFormData(form);
            var data = formData.data;

            // If a honeypot field is filled, assume it was done so by a spam bot.
            if (formData.honeypot) {
                return false;
            }

            disableAllButtons(form);
            var url = form.action;
            var xhr = new XMLHttpRequest();
            xhr.open('POST', url);
            // xhr.withCredentials = true;
            xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
            xhr.onreadystatechange = function () {
                console.log(xhr.status, xhr.statusText);
                console.log(xhr.responseText);
                form.reset();

                return;
            };
            // url encode form data for sending as post data
            var encoded = Object.keys(data).map(function (k) {
                return encodeURIComponent(k) + "=" + encodeURIComponent(data[k]);
            }).join('&');
            xhr.send(encoded);
        }

        function disableAllButtons(form) {
            var buttons = form.querySelectorAll("button");
            for (var i = 0; i > buttons.length; i++) {
                buttons[i].disabled = true;
            }
        }


    }

如前所述，我有喬，我需要將他的電話號碼更新為456

| NAME  |  NUMBER | 
|-------|---------|
|Joe    |123      |
|Brian  |420      |
|Raine  |143      |

所以預期結果應該是

| NAME  |  NUMBER | 
|-------|---------|
|Joe    |456      |
|Brian  |420      |
|Raine  |143      |

附加說明：該代碼有效，但是當我插入新數據時，我無法擺脫時間戳。 我如何擺脫它？

Answer 1

我將此答案分為兩個部分：

1.擺脫時間戳記

如您在Google Appscript代碼中看到的：

var row = [new Date()]; // first element in the row should always be a timestamp

您只需要刪除新的Date（）函數，並將其保留為空數組聲明即可：

var row = []; //There is no first element yet.

在此之后，有一個for循環，其索引從1開始以避免Timestamp，但是由於我們已將其刪除，因此無需從1開始，因此我們必須對其進行更改。

 for (var i = 0; i < oldHeader.length; i++) { // Now we start at 0 instead of 1
      var field = oldHeader[i];
      var output = getFieldFromData(field, e.parameters);
      row.push(output);
      ....

2.根據條件更新單元

由於您已經知道名稱的條件（Joe）來更新Number，因此我們只需要將A中每個單元格的值與字符串'Joe' ：

function updateCell() {

  var doc = SpreadsheetApp.getActiveSpreadsheet(); //this line is not necessary if you just paste this code in yours

  var names = doc.getRange("A2:A").getValues(); //We store all the names from A2 to the last one
  var newValue = '456';

  for (var n = 2; n < names.length + 2; n++){ //We start at 2 since A1 and B1 are the headers of the table

    if (names[n - 2] == 'Joe'){ //But the array's first position is 0, so we deduct 2 form n.

      doc.getRange("B" + (n)).setValue(newValue);
    }
  }
}

結果：
