您需要在正则表达式中转义正斜杠
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname)

这是双斜线，
if (location.pathname.replace(/^/,'') == this.pathname.replace(/^/,'') && location.hostname == this.hostname)

使用RegExp构造函数
var regexp = new RegExp("^/", "");
if (location.pathname.replace(regexp,'') == this.pathname.replace(regexp,'') && location.hostname == this.hostname)
或转义字符/
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname)
