jQuery回调未触发

Question

I've got a line of code that looks like this where the callback never gets executed:

        GroupRepository.Add("#divSortingArea", oGroup, oSow.AddGroupToPage, (function() { alert(123); }));

Thks guys, no alert popup !

Cheers, Shotemba

here is the full code:

function GroupRepository() { }

GroupRepository.Add = function(targetSelection, oGroup, addToPage) {

var tableToInsert = null;

var nGroupID = oGroup.nScopeOfWorkGroupID;
var sDescription = oGroup.sScopeOfWorkGroupDescription;


Eclipse3.GroupService.InsertGroup(Globals.N_JOB_ID, oGroup, InsertGroup_Success, InsertGroup_Error);

function InsertGroup_Success(response) {
    nGroupID = parseInt(response.nIdentity);
    var bConcurrencyId = response.bNewConcurrencyId;

    //If this entry contains rows pull those rows out,
    var rows = tableToInsert.find("tbody tr");
    tableToInsert.remove();

    oGroup.nScopeOfWorkGroupID = nGroupID;
    oGroup.bConcurrencyId = bConcurrencyId;

    var newGroupElement = addToPage(oGroup);

    //add to the new group being created,
    newGroupElement.find("tbody").append(rows);


    //Globals.DisplayMessage("Insert Succeeded", "Your attempt to add a new record was successful.");
    Globals.DisplayMessage("Insert Group Succeeded", "A new record was added.");

    return this;
};

function InsertGroup_Error(error) {

    Globals.HandleError("Item Group Failed", error);
};

}

Answer 1

In your GroupRepository.Add there's only 3 parameters, targetSelection, oGroup and addToPage. To extend the callback, declare a new function:

function newCallBack(param) {
   var result = oSow.AddGroupToPage(param);
   alert(123);
   return(result);
}

and then:

GroupRepository.Add("#divSortingArea", oGroup, newCallBack);
