使用 jQuery Address 更改后退按钮上的页面标题

利用 jQuery Address 启用浏览器的后退按钮，我能够利用插件的事件“onExternalChange”来检测浏览器何时实际点击后退按钮，以便我也可以触发页面标题更改。不幸的是，我无法让它抓住当前部分，因为它在跳跃之前抓住它，因此每次都是一次：

$.address.externalChange(function() {
    var lastPageTitle = 'Kevin Dare Foundation | ' + $('nav').find('.active').html();
    $.address.title(lastPageTitle);
});

Utilizing jQuery Address to enable the browser's back button, I was able to leverage the plugin's event "onExternalChange" to detect when the browser actually hits the back button, so that I could trigger the page title to change on that as well. Unfortunately I can't get it to grab the current section, as it grabs it before it jumps, thus being one off everytime:

$.address.externalChange(function() {
    var lastPageTitle = 'Kevin Dare Foundation | ' + $('nav').find('.active').html();
    $.address.title(lastPageTitle);
});

看起来以下问题可以解决：

//Change Page Title on browser back button press
$.address.externalChange(function() {
    var hash = document.location.hash.replace(/^#\//, '');
    var lastPageTitle = 'Kevin Dare Foundation | ' + $('nav a[href="#'+hash+'"]').html();
    if(hash) {
    $.address.title(lastPageTitle);
    }
    else //account for no hash
  {
  $.address.title('Kevin Dare Foundation');
  }
});

Looks like the following solves the problem:

//Change Page Title on browser back button press
$.address.externalChange(function() {
    var hash = document.location.hash.replace(/^#\//, '');
    var lastPageTitle = 'Kevin Dare Foundation | ' + $('nav a[href="#'+hash+'"]').html();
    if(hash) {
    $.address.title(lastPageTitle);
    }
    else //account for no hash
  {
  $.address.title('Kevin Dare Foundation');
  }
});
