postData没有传递任何参数！ [英] postData not passing any parameters!

问题描述

我看不到任何参数值在Firebug中传递给服务器.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

您当前serializeGridData的实现只需从中删除所有函数参数.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Web浏览器中本地实现.

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.
