我有来自 codelifter 的这个脚本，它工作得很好。我希望如果下面的引用包含一个 url，那么它就会变成可点击的。任何帮助都会很棒。谢谢

function showQuotation(){
    if(Quotation[whichQuotation].substr(0,7)=='http://' || Quotation[whichQuotation].substr(0,8)=='https://')
    document.write('<a href="'+Quotation[whichQuotation]+'">'+Quotation[whichQuotation]+'</a>');
    else
    document.write(Quotation[whichQuotation]);
}

这就是我要做的：

  1. 假设报价以 http(s):// 开头
  2. 在 ShowQuotation 中：使用正则表达式来识别此类字符串。可能是不必要的复杂。检查长度为 7 的子字符串是否为http://或长度为 8 的子字符串为https://，假设其余部分都是 URL 的一部分
  3. 使其成为链接
