获取激活选项卡的索引
问题描述：
我正在将代码从jQuery UI 1.8升级到1.10.
I'm upgrading code from jQuery UI 1.8 to 1.10.
在1.8下，选项卡更改时触发的事件是select，我可以通过ui.index访问所选择的选项卡的索引.
Under 1.8, the event triggered when the tab changes was select, and I could access the index of the tab being selected through ui.index.
在1.10下，选项卡更改时触发的事件为activate.但是，我无法在事件参数ui中找到任何内容来告诉我新激活的选项卡的索引.
Under 1.10, the event triggered when the tab changes is activate. However, I cannot find anything in the event parameter ui that tells me the index of the newly activated tab.
如何找到该索引?
答
您可以使用以下方法 http://jsfiddle.net/9ChL5/1/:
$("#tabs").tabs({
activate: function (event, ui) {
console.log(ui.newTab.index());
}
});
