升级到jQuery UI 1.10时如何更改"cache"和"ajaxOptions"? [英] How to change `cache` and `ajaxOptions` when upgrading to jQuery UI 1.10?

问题描述

自从我升级到jQuery UI 1.10以来，发生了一些变化.在升级之前，与我的 jQuery UI Tab 相关的代码如下:

Since I upgraded to jQuery UI 1.10 something has changed. Before that upgrade, code related to my jQuery UI Tab was the following:

$('.selector').tabs({
  cache: true,
  ajaxOptions: {
    dataType: 'html'
  }
 });

如 jQuery中所述UI 1.10升级指南，cache和ajaxOptions均已删除.该指南还指出要使用beforeLoad事件，但是如何也可以升级代码?

As wrote in the jQuery UI 1.10 Upgrade Guide, both cache and ajaxOptions has been removed. The guide also states to use the beforeLoad event, but how can I upgrade the code as well?

推荐答案

一种可行的方法是:

$(".selector").tabs({
    beforeLoad: function (event, ui) {
        if ( ui.tab.data( "loaded" ) ) {
          event.preventDefault();
          return;
        }
        ui.jqXHR.success(function() {
          ui.tab.data( "loaded", true );
        });
    }
});
