從表中選擇單元格值

Question

我在表中有多個記錄..場景，當我單擊行然后按ID顯示圖表時，現在我想指定哪個所有者擁有此數據，因此為此我嘗試顯示所有者名稱..

我在表中有數據：

ID      Owner RegNo 
26626   John  B82       
26634   David BE49  
26642   Roh   A5    
26640   Julie B5    

我嘗試了這個：

 <script type="text/javascript">

    $(function () {
        $('#tabledata').on('click', 'tr', function () {
            var row = $(this);
            var Id = row.find('td')[0].firstChild.data;
            var cell = row.find('td')[1].firstChild.data;
            var obj = {};
            var cellvalue = {};
            obj.ID = Id;
            cellvalue.cell = cell;
            GetData(obj);
            return false;
        });
    });
function GetData(obj) {
    $.ajax({
        type: "POST",
        url: "WebForm1.aspx/GetVo",

                return;
            }

            var myarray = eval(strArray);

當我檢查f12時，顯示錯誤

修改您的函數調用和函數定義：

<script type="text/javascript">
