如何使用jQuery将recaptcha的值发送到另一个页面？

string finalSelectedValue = specificPair(testDictionary,memberId);

JS：

<head>
<script src='https://www.google.com/recaptcha/api.js'></script>
</head>
<body>
...

<form>
<div class="g-recaptcha"  data-size="normal" data-sitekey="xxxxxxxxxxxx"></div>
<input type="sumbit" />
</form>

我也试试：

$.post('index.php', { 
     hiddenRecaptcha: grecaptcha.getResponse(),
...

从official reference读取;有三种方法，但是你在这里用javascript发送，所以在你的表单中进行以下更改

PS：记住脚本顺序，否则你将无法获得recaptcha

为您的recaptcha div

分配一个唯一的ID

if (newRows.Count > 0)
{
    //Increment through our array list and build a 2D string array from that list (.Range.Value doesnt like ArrayList objects, so we must use a raw 2D array)...
    string[] rowSample = (string[])newRows[0];
    string[,] newRowsArray = new string[newRows.Count, rowSample.Length];
    int currentRowIndex = 0;
    foreach (string[] row in newRows)
    {
        int columnIndex = 0;
        foreach (string columnText in row)
        {
            newRowsArray[currentRowIndex, columnIndex] = columnText;
            columnIndex++;
        }

        currentRowIndex++;
    }

    //Hold processing while the current excel file is open, once it closes we can continue...
    HoldWhileFileIsOpen(currentExcelFile);
    try
    {
        //Open excel and open current workbook...
        Microsoft.Office.Interop.Excel.Application excelApplication = new Microsoft.Office.Interop.Excel.Application();
        excelApplication.DisplayAlerts = false;
        excelApplication.Visible = false;
        Microsoft.Office.Interop.Excel.Workbooks excelWorkbooks = excelApplication.Workbooks;

        Microsoft.Office.Interop.Excel.Workbook currentWorkbook = excelWorkbooks.Open(currentExcelFile, Type.Missing, false, Type.Missing, Type.Missing, Type.Missing, true, Type.Missing, Type.Missing, Type.Missing, false, Type.Missing, false, Type.Missing, Type.Missing);

        //Open up/Select our current worksheet
        Microsoft.Office.Interop.Excel.Sheets workSheets = currentWorkbook.Sheets;
        Microsoft.Office.Interop.Excel.Worksheet currentWorkSheet = workSheets[currentWorkSheetName];
        currentWorkSheet.Select();
        //Create new range, set range number formatting = "@" (text) to retain leading zeroes and other tricky bits in our output, then drop values into range...
        Microsoft.Office.Interop.Excel.Range newExcelRows = (Microsoft.Office.Interop.Excel.Range)currentWorkSheet.get_Range(GetColumnAddress(startingColInt) + startingRow, GetColumnAddress(startingColInt + rowSample.Length - 1) + (startingRowIncrementing - 1));
        newExcelRows.NumberFormat = "@";
        //newExcelRow.Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);
        newExcelRows.Value = newRowsArray;

        //Save workbook changes...
        currentWorkbook.SaveAs(currentExcelFile, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,  Microsoft.Office.Interop.Excel.XlSaveConflictResolution.xlLocalSessionChanges, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

        //Close things up, all COM objects references above must be released and scrubbed thouroughly...
        System.Runtime.InteropServices.Marshal.ReleaseComObject(newExcelRows);
        newExcelRows = null;
        excelApplication.ActiveWorkbook.Close(Type.Missing, Type.Missing, Type.Missing);
        System.Runtime.InteropServices.Marshal.ReleaseComObject(currentWorkSheet);
        currentWorkSheet = null;
        System.Runtime.InteropServices.Marshal.ReleaseComObject(workSheets);
        workSheets = null;
        System.Runtime.InteropServices.Marshal.ReleaseComObject(currentWorkbook);
        currentWorkbook = null;

        //Quit excel...
        excelWorkbooks.Close();
        System.Runtime.InteropServices.Marshal.ReleaseComObject(excelWorkbooks);
        excelWorkbooks = null;
        excelApplication.Quit();
        System.Runtime.InteropServices.Marshal.ReleaseComObject(excelApplication);
        excelApplication = null;
    }
    catch (Exception ex)
    {
        if (ex.Message == "Cannot save as that name. Document was opened as read-only.")
        {

        }
    }
    //Hold processing while the current excel file is open, once it closes we can continue...
    HoldWhileFileIsOpen(currentExcelFile);

    LblStatus.AppendText(" - Done modifying and saving worksheet " + currentWorkSheetName + " (" + currentCountry + ")." + Environment.NewLine);
}
else
{
    LblStatus.AppendText(" - No data found for current worksheet " + currentWorkSheetName + " (" + currentCountry + ")." + Environment.NewLine);
}

现在

<div class="g-recaptcha" id="my-recaptcha" data-size="normal"></div>

in

<script type="text/javascript">
      var my_recaptcha_widget;
      var onloadCallback = function() {
        if($('#my-recaptcha').length) {
            my_recaptcha_widget = grecaptcha.render('my-recaptcha', {
              'sitekey' : '6LfbhhQTAAXXXXXXXXXXXXXCJlFajw'
            });
        }
 };      
</script>
<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit" async defer></script>
