如何用链接替换普通URL?我使用下面的函数来匹配给定文本中的URL,并将它们替换为HTML链接。正则表达式工作得很好,但目前我只替换第一场比赛。我怎样才能替换所有的URL?我想我应该用主管但我真的不知道该怎么做。function replaceURLWithHTMLLinks(text) {
var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/i;
return text.replace(exp,"<a href='$1'>$1</a>"); }

function linkify(inputText) {
var replacedText, replacePattern1, replacePattern2, replacePattern3;
//URLs starting with http://, https://, or ftp://
replacePattern1 = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim;
replacedText = inputText.replace(replacePattern1, '<a href="$1" target="_blank">$1</a>');
//URLs starting with "www." (without // before it, or it'd re-link the ones done above).
replacePattern2 = /(^|[^\/])(www\.[\S]+(\b|$))/gim;
replacedText = replacedText.replace(replacePattern2, '$1<a href="http://$2" target="_blank">$2</a>');
//Change email addresses to mailto:: links.
replacePattern3 = /(([a-zA-Z0-9\-\_\.])+@[a-zA-Z\_]+?(\.[a-zA-Z]{2,6})+)/gim;
replacedText = replacedText.replace(replacePattern3, '<a href="mailto:$1">$1</a>');
return replacedText;}添加回答
