如何替换函数参数？

我使用以下代码进行 ajax 调用，其中表单数据作为参数传递。

//ajax call
function restServiceCall(origin,destination,tripType,dateDepart,dateReturn){

    dataString = 'origin='+ origin + '&destination=' + destination + '&tripType='+tripType;

     $.jsonp({
          "url": flightURL,
          callbackParameter:jsonpCallBack,
          data: dataString,
    beforeSend:function(){$('#loadingdiv').show()},
           "success": function(data) {
                        if(data.error != null){
                            $('#errtitle').html('<h2 class="pgtitle">Error !! &nbsp;'+data.error+'</h2>').show();
                            $("#displaydiv,loadingdiv").hide();
                        }else{
                          renderData (data,dateDepart,dateReturn);
                      }
           },

            "error": function(xOptions, textStatus) {
               $('#errtitle').html('<h2 class="pgtitle">Sorry the service you are looking for is currently unavailable</h2>').show();
               $("#displaydiv,loadingdiv").hide();
           }
 });
}

除了从表单进行调用之外，我还在以下函数中使用它，其中我只需要传递 dateDepart/dateReturn 作为参数。

//for pagination
$('.pagenation a').bind('click',function(){
        var numDays = 7;
        var self = $(this);

        var dateTemp = self.parents(':eq(1)').attr('id')=="onewaytripdiv"? parseDate(dateDepart):parseDate(dateReturn);

        if(self.hasClass('left')){
            var tempDepDate = removeNumOfDays(dateTemp,numDays);
        }else{
            var tempDepDate = addNumOfDays(dateTemp,numDays);
        }
        var changedDate = tempDepDate.getDate()+' '+cx.monthNamesShort[tempDepDate.getMonth()]+' '+tempDepDate.getFullYear();
        if(self.parents(':eq(1)').attr('id')=="onewaytripdiv"){
            dateDepart = changedDate;
        }else{
            dateReturn = changedDate;
        }   
    restServiceCall(origin,destination,tripType,dateDepart,dateReturn);
});

我想删除函数调用中的参数，因为参数可能会有所不同。请建议一种传递参数的替代方案。

原文

I'm using the following code to make ajax call where the form data is passed as params.

//ajax call
function restServiceCall(origin,destination,tripType,dateDepart,dateReturn){

    dataString = 'origin='+ origin + '&destination=' + destination + '&tripType='+tripType;

     $.jsonp({
          "url": flightURL,
          callbackParameter:jsonpCallBack,
          data: dataString,
    beforeSend:function(){$('#loadingdiv').show()},
           "success": function(data) {
                        if(data.error != null){
                            $('#errtitle').html('<h2 class="pgtitle">Error !!  '+data.error+'</h2>').show();
                            $("#displaydiv,loadingdiv").hide();
                        }else{
                          renderData (data,dateDepart,dateReturn);
                      }
           },

            "error": function(xOptions, textStatus) {
               $('#errtitle').html('<h2 class="pgtitle">Sorry the service you are looking for is currently unavailable</h2>').show();
               $("#displaydiv,loadingdiv").hide();
           }
 });
}

Besides making the call from form I also use it in the following function wherein I just need to pass either the dateDepart/dateReturn as params.

//for pagination
$('.pagenation a').bind('click',function(){
        var numDays = 7;
        var self = $(this);

        var dateTemp = self.parents(':eq(1)').attr('id')=="onewaytripdiv"? parseDate(dateDepart):parseDate(dateReturn);

        if(self.hasClass('left')){
            var tempDepDate = removeNumOfDays(dateTemp,numDays);
        }else{
            var tempDepDate = addNumOfDays(dateTemp,numDays);
        }
        var changedDate = tempDepDate.getDate()+' '+cx.monthNamesShort[tempDepDate.getMonth()]+' '+tempDepDate.getFullYear();
        if(self.parents(':eq(1)').attr('id')=="onewaytripdiv"){
            dateDepart = changedDate;
        }else{
            dateReturn = changedDate;
        }   
    restServiceCall(origin,destination,tripType,dateDepart,dateReturn);
});

I would like to remove the params in the function call, as the params may vary. Please suggest an alternative to pass the params.

传递一个参数数组怎么样？然后传递另一个值，例如整数，以向函数指示其参数数组中期望的内容。

例如

restServiceCall(myParams, 0);

How about passing an array of parameters instead? And then pass another value, such as an integer to indicate to the function what to expect in it's parameter array.

e.g
