Ajax在移至下一部分之前先运行部分代码（延迟）

Question

我有一些正在被调用的代码，它遍历我的$ .ajax（）的开头，在退出并进入下一部分之前，我需要它遍历整个方法，因为直到将其正确组合为止它一直贯穿目前它开始，然后退出并跳过我的延迟，并进入if（woimageindex> = 0）条件

这是我的代码。我需要if（woimageindex == -1）来运行并通过defer.done（function（）{，但它跳过了本节中的所有内容。在继续之前，我该如何做到这一点？

if (woimageindex == -1)//item not found
                        {
                            var ajaxRequests = [];

                            url = rootPath + "utility/GetWebRequestImages";                          

                            ajaxRequests.push($.ajax({
                                type: 'POST',
                                url: url,
                                data: {
                                     corp_id: WOCorp_id
                                },
                                dataType: 'json'
                            }));

                            var defer = $.when.apply($, ajaxRequests);
                            defer.done(function () {
                                // This is executed only after every ajax request has been completed
                                $.each(arguments, function (index, responseData) {
                                    switch (index) {
                                        case 0://status
                                            //populate the AutoCompleteDataSource with the data from server
                                            arrWOWebRequestImagesList.push(new PickListModel(WOCorp_id, responseData));
                                            woimageindex = arrWOWebRequestImagesList.length - 1;
                                            break;
                                    }
                                    //alert(index);
                                });//end of switch
                            });//end of defer
                        }

                        if (woimageindex >= 0)
                        {
                            var categories = arrWOWebRequestImagesList[woimageindex].list;
                            alert(categories.length);
                            var list = [];

                            // added new PickListModel(webimage_id, after .push(
                                //list.push(new PickListModel(webimage_id, $.map(arrWOWebRequestImagesList[woimageindex].list, function (item) {
                            list.push( $.map(arrWOWebRequestImagesList[woimageindex].list, function (item) {
                                return new PickListItem(item.caption, item.caption, item.webimage_id);
                            }));
