history.back
是一个函数。你必须把它称为一个函数。通过分配到window.location
返回导航历史记录不起作用。
让您的代码根据点击链接的href有所不同。
$('a').click(function (e)
{
e.preventDefault();
var newLocation = this.href;
$('body').fadeOut(250, newPage);
function newPage()
{
if(newLocation == "javascript:history.back()")
{
history.back();
}
else
{
window.location = newLocation;
}
}
});

你为什么不就叫'history.back()''中的新页'? – NineBerry
该代码应该在页面上的所有链接上工作,并且大多数链接都是常规链接......设置固定值会打败整个目的。 –
(1)正如文中建议'javascript:history.back()'是历史对象上的JavaScript方法,它不是一个url。 (2)使用'document.referrer'作为url。 – Abhitalks
