Question

代码可以正常工作，直到调用页面方法为止。这是麻烦的功能

SetCellValueFromKey = (row, CellName, totalQty);

该函数是另一个js文件

function SetCellValueFromKey(theRow, theKey, setValue) {
    theRow.get_cellByColumnKey(theKey).set_value(setValue);
}

这是我的页面方法功能

 PageMethods.GetSalesOrderInfo(dteStartDate, dteEndDate, ProductsArray, GetSalesOrderInfoCallSuccess, GetSalesOrderInfoCallFailed);
 return false;

这是GetSalesOrderInfoCallSuccess函数

function GetSalesOrderInfoCallSuccess(result) {

     var lbActualSales = document.getElementById("<%=lbActualSales.ClientID%>");
     var hdnWeekNumOfWeekYear = document.getElementById("<%=hdnWeekNumOfWeekYear.ClientID%>").value;
     // Code to handle a Success from 'GetActualSalesInfoCallSuccess'
     //if result it not null, parse the data
     if (result != null) {
         var jsResult = JSON.parse(result);

         //clear the Actual Sales list box  
         var NumRows = lbActualSales.length;
         if (NumRows != 0) {
             for (var i = NumRows - 1; i >= 0 ; i--) {
                 //remove the row  
                 lbActualSales.options.remove(i);
             }
         }
         NumRows = jsResult.length;
         var optionNum = 0;
         if (NumRows > 0) {
             for (var i = 0; i < NumRows; i++) {
                 var dataRow = jsResult[i];                   
                 //Add the new data into Actual Sales ListBox 
                 var option = "option" + optionNum;
                 option = document.createElement("option");
                 lbActualSales.options.add(option, lbActualSales.options.length);
                 strRow = [dataRow.SalesOrderId] + "|" + [dataRow.ProductId] + "|" + [dataRow.Quantity] + "|" + [dataRow.Weight] + "|" + [dataRow.UnitPrice] + "|" + [dataRow.TotalPrice] + "|" + [dataRow.ListPrice] + "|" + [dataRow.SalesOrderNum] + "|" + [dataRow.CustomerId] + "|" + [dataRow.DateCreated] + "|" + [dataRow.CustomerName] + "|" + [dataRow.UnitOfSale] + "|" + [dataRow.Product_Name] + "|" + [dataRow.Week] + "|" + [dataRow.OrderType];
                 option.text = strRow;
                 option.value = [dataRow.ProductId] + "|" + [dataRow.Week];
                 optionNum = optionNum + 1;
             }
         }             

         var grid = getGrid("<%=wdgSalesForecast.ClientID%>");
         var search = "";
         var totalQty = 0;
         NumRows = lbActualSales.length;
         //for each row in grid get the ProductId and the week to search into the listBox 
         for (var i = 0; i < grid.get_rows().get_length() ; i++) {
             var row = grid.get_rows().get_row(i);
             var productId = getCellValueFromKey(row, "ProductId");
             search = productId;
             //loop through the row to change each value for Actual Sales 
             for (var j = 0; j < row.get_cellCount() ; j++) {
                 var cell = row.get_cell(j);
                 var CellName = cell._column._key;                    
                 //get the week num and build a string "search"
                 if (CellName.search("ActAmtWk") > -1) {
                     var WeekNum = CellName.split("ActAmtWk");
                     WeekNum = WeekNum.pop();
                     var weekNumOfYear = parseInt(WeekNum) + parseInt(hdnWeekNumOfWeekYear) - 1;
                     search = search.concat("|");
                     search = search.concat(weekNumOfYear);

                     //loop through the Actual Sales List box and search for the product for the specific week 
                     for (var count = 0; count < NumRows; count++) {
                         if (search == lbActualSales.options[count].value) {
                             var splitValues = lbActualSales.options[count].text.split("|");
                             // Calculate the Qty                       
                             totalQty = totalQty + parseInt(splitValues[7]);
                         }
                     }
                     //update the Forecast Grid cell with the New Value
                     SetCellValueFromKey = (row, CellName, totalQty);
                 }
                 //reset my search string and totalQty
                 search = productId;
                 totalQty = 0;
             } 
         }
         UpdateDemandForecast();

     }//end of result test 
  alert('Data Updated successfully');
 }//end of function `

ps。我从同一个js文件调用其他函数，但我没有问题。

Answer 1

您的代码行是一个赋值语句，这就是它引起您问题的原因：

SetCellValueFromKey = (row, CellName, totalQty);

您已经创建了函数SetCellValueFromKey(theRow, theKey, setValue)，因此要调用该函数，您应该使用：

SetCellValueFromKey(row, CellName, totalQty);

Answer 2

尝试给予关注

SetCellValueFromKey(row, CellName, totalQty);

代替

SetCellValueFromKey = (row, CellName, totalQty);

我收到以下错误Javascript运行时错误：预期功能
