我有一個麻煩，我正在開發一個代碼，以顯示10個正在從xml文件饋入的雜誌。我有它的工作在一定程度上，FF和IE7 + 8不喜歡它，也許因爲它說在第62行有一個錯誤 - 作爲調用數據被喂入的核心函數。從XML文件分頁的jQuery結果集問題
這是我的代碼：

success: function(xml) {
var shelf = $('#shelf-items');
var startIndex = 0;
var howMany = 10;
var $issues = $(xml).find('issue');
var totalIssues = $issues.length;
var numPages = Math.ceil(totalIssues/howMany)
$('span.issuecount').html(+totalIssues+' Issues - '+numPages+' Pages');
var displayIssues = function() {
var $issuesPaginated = $issues.slice(startIndex , (totalIssues - startIndex) + howMany);
$('#shelf-items li').fadeOut(500);

});
}
$('#prevIssueButton').click(function() {
if(startIndex < howMany) {

displayIssues();

上一步和下一步按鈕不能正常工作，比如我點擊下一步，我去第2頁，再點擊下一步 - 它的空白，並單擊最後一次我被告知我沒有更多的結果查看。但是，如果我點擊上一步開始並返回3次（再次開始），然後單擊下一步我可以循環回到同一問題，這真的讓我感到困惑，任何幫助將深表感謝！
