我有一个网页，其中包含在第二个到第四个选项卡中加载的 iFrame 的 JQuery 选项卡。我的问题出在我添加到第一个选项卡的按钮中。我希望该按钮在按下时更改为下一个选项卡。
编辑1：这是一个显示我的问题的提琴手。http://jsfiddle.net/lochalan/AXa9J/

Javascript / JQueryUI：
$(document).ready(function() {
var $tabs = $('#tabs').tabs();
$(".nexttab").click(function() {
var selected = $("#tabs").tabs("option", "selected");
$("#tabs").tabs("option", "selected", selected + 1);
});
//get selected tab
function getSelectedTabIndex() {
return $tabs.tabs('option', 'selected');
}
//get tab contents
beginTab = $("#tabs ul li:eq(" + getSelectedTabIndex() + ")").find("a");
loadTabFrame($(beginTab).attr("href"),$(beginTab).attr("rel"));
$("a.tabref").click(function() {
loadTabFrame($(this).attr("href"),$(this).attr("rel"));
});
//tab switching function
function loadTabFrame(tab, url) {
if ($(tab).find("iframe").length == 0) {
var html = [];
html.push('<div class="tabIframeWrapper">');
html.push('<div class="openout"><a href="' + url + '"><img src="data/world.png" border="0" alt="Open" title="Remove iFrame" /></a></div><iframe class="iframetab" src="' + url + '">Load Failed?</iframe>');
html.push('</div>');
$(tab).append(html.join(""));
$(tab).find("iframe").height($(window).height()-80);
}
return false;
}
});
为什么我的按钮不会更改选项卡？
