Checkbox 将复选框数据从html web表单保存到Google电子表格

除了函数没有选择复选框值之外，我的函数脚本工作得很好。相反，这些特定列只是在电子表格单元格中显示未定义。我的函数缺少什么，使它能够从html web表单中选择复选框值

我的html表单：

<form id="registration-form" action="https://script.google.com/macros/s/AKfycbx_fFp-WWHLvRV4SgSq-JPklxwZIyZnCD_04-zHzUYhjcwGpier/exec">
        <div class="grid-container">
            <div class="grid-x grid-padding-x">
                <div class="large-12 cell">
                    <fieldset>
                        <label>Check In:
                            <input type="date" name="checkin_date">
                        </label>
                    </fieldset>
                    <hr>
                    <fieldset>
                        <label>Check Out:
                            <input type="date" name="checkout_date">
                        </label>

                        </label>

                </div>
            </div>
        </div>
    </div>
</form>

如果希望它仅在选中复选框时写入值，请尝试向复选框元素添加值属性，例如

<input id="checkboxno" type="checkbox" name="attending_IDIA_meeting" value="true"><label for="checkboxno">Yes</label>

如果要在检查或未检查时写入值，请考虑切换到选项输入。有关这方面的更多详细信息，请参阅。不管怎样，选项输入可能会更好地满足您的需要。

它工作得非常好，我想知道我的脚本如何在网页中显示成功消息，而不是在空白页上打印json结果。我该怎么办？我正在使用window.alert方法，但它不起作用。请查看。

    var lock = LockService.getPublicLock();
    lock.waitLock(30000); // wait 30 seconds before conceding defeat.

try {
    // next set where we write the data - you could write to multiple/alternate destinations
    var doc = SpreadsheetApp.openById(SCRIPT_PROP.getProperty("key"));
    var sheet = doc.getSheetByName(SHEET_NAME);

    // we'll assume header is in row 1 but you can override with header_row in GET/POST data
    var headRow = e.parameter.header_row || 1;
    var headers = sheet.getRange(1, 1, 1, sheet.getLastColumn()).getValues()[0];
    var nextRow = sheet.getLastRow() + 1; // get next row
    var row = [];
    // loop through the header columns
    for (i in headers) {
        if (headers[i] == "Timestamp") { // special case if you include a 'Timestamp' column
            row.push(new Date());
        } else { // else use header name to get data
            row.push(e.parameter[headers[i]]);
        }
    }
    // more efficient to set values as [][] array than individually
    sheet.getRange(nextRow, 1, 1, row.length).setValues([row]);
    // return json success results
    return ContentService
        .createTextOutput(JSON.stringify({
            "result": "success",
            "row": nextRow
        }))
        .setMimeType(ContentService.MimeType.JSON);
} catch (e) {
    // if error return this
    return ContentService
        .createTextOutput(JSON.stringify({
            "result": "error",
            "error": e
        }))
        .setMimeType(ContentService.MimeType.JSON);
} finally { //release lock
    lock.releaseLock();
}
}

function setup() {
    var doc = SpreadsheetApp.getActiveSpreadsheet();
    SCRIPT_PROP.setProperty("key", doc.getId());
}

<input id="checkboxno" type="checkbox" name="attending_IDIA_meeting" value="true"><label for="checkboxno">Yes</label>
