postData 没有传递任何参数！

问题描述

我无法在 firebug 中看到任何传递给服务器的参数值.这是代码.

I'm not able to see any parameters value passing to server in firebug. Here is the code.

//BuyBackGridInit() start

function BuyBackGridInit(tabID){


        $('table[id$="'+tabID+'_BuyBackGrid"]').jqGrid({
            url :'/Controls/Advertiser/BuyBackControlNew.ascx.ashx?action=getBuyBackData',
            datatype: 'json',
            mtype: 'POST',
            height:'100%',
            width:'100%',
            colNames: result.colNamesData,
            colModel: result.colModelData,
            postData: {
              advertiserID: function() { return $('#advertiser_id').text(); },
              CampaignsDdlSelectedValue: function() { return $('select[id$="CampaignDdl"] option:selected').val(); },
              startDate: function() { return $('input[id$="'+tabID+'_FromCalBuyBack_CalendarTbx"] ').val(); },
              endDate: function() { return $('input[id$="'+tabID+'_ToCalBuyBack_CalendarTbx"] ').val(); }
            },
            rowNum : 100,
            shrinkToFit :false,
            altRows: true,
            altclass:'altRow',
            autowidth: true,
            multiselect: true,
            gridComplete:function (){
              var recs = parseInt( $('table[id$="'+tabID+'_BuyBackGrid"]').getGridParam("records"),10);
              if (recs == 0){
                  $('div[id$="'+tabID+'_NoDataFoundBuyBackdiv"]').show();
                  $('input[id$="AddToCartBtn"]').hide();
                  $('input[id$="BuyBackDownloadBtn"]').hide();
              }
              else {
                  $('div[id$="'+tabID+'_NoDataFoundBuyBackdiv"]').hide();
                  $('input[id$="AddToCartBtn"]').show();
                  $('input[id$="BuyBackDownloadBtn"]').show();
              }
            },
            serializeGridData: function (data){
               return $.toJSON(data);
            }
        });//end of jQuery("#BuyBackGrid").jqGrid()

}//BuyBackGridInit() End

推荐答案

你当前的 serializeGridData 实现只是 remove 从 postData.因此，您应该在 serializeGridData 内扩展 data 参数，而不是使用 postData.另一种方法是将 serializeGridData 修改为以下内容:

You current implementation of serializeGridData just remove all functions parameters from the postData. So you should either extend data parameter inside of serializeGridData instead of the usage of postData. Another way is to modify serializeGridData to the following:

serializeGridData: function (data){
    var propertyName, propertyValue, dataToSend = {};
    for (propertyName in data) {
        if (data.hasOwnProperty(propertyName)) {
            propertyValue = data[propertyName];
            if ($.isFunction(propertyValue)) {
                dataToSend[propertyName] = propertyValue();
            } else {
                dataToSend[propertyName] = propertyValue
            }
        }
   }
   return JSON.stringify(dataToSend);
}

在上面的代码中，我们枚举了所有属性并显式调用了所有函数.此外，我更喜欢使用 json2.js 中的 JSON.stringify 函数.该功能将在许多网络浏览器中原生实现.

In the code above we enumerate all properties and call all functions explicitly. Moreover I prefer to use JSON.stringify function from json2.js. The function will be native implemented in many web browsers.
