[英]Replacing pasted links with active hyperlinks in JavaScript / jQuery
For my chat I need a jquery or javascript function that translates pasted links like http://example.com
to active links like <a href="http://example.com">http://example.com</a>
对于我的聊天,我需要一个jquery或javascript函数,将粘贴的链接(如http://example.com
为活动链接(如<a href="http://example.com">http://example.com</a>
Frankly I'm still quite bad with Regular Expressions (they somethimes looks like names of bohemian villages ;-)) and therefore I need your help. 坦白说,我对正则表达式仍然很不满意(它们的某些主题看起来像波希米亚村庄的名称;-),因此我需要您的帮助。 I'd like to translate the following PHP function into JavaScript / jQuery 我想将以下PHP函数转换为JavaScript / jQuery
function addHyperlinks($text){
return preg_replace(
array(
'/(?(?=<a[^>]*>.+<\/a>)
(?:<a[^>]*>.+<\/a>)
|
([^="\']?)((?:https?|ftp|bf2|):\/\/[^<> \n\r]+)
)/iex',
'/<a([^>]*)target="?[^"\']+"?/i',
'/<a([^>]+)>/i',
'/(^|\s)(www.[^<> \n\r]+)/iex',
'/(([_A-Za-z0-9-]+)(\\.[_A-Za-z0-9-]+)*@([A-Za-z0-9-]+)
(\\.[A-Za-z0-9-]+)*)/iex'
),
array(
"stripslashes((strlen('\\2')>0?'\\1<a href=\"\\2\">\\2</a>\\3':'\\0'))",
'<a\\1',
'<a\\1 target="_blank">',
"stripslashes((strlen('\\2')>0?'\\1<a href=\"http://\\2\">\\2</a>\\3':'\\0'))",
"stripslashes((strlen('\\2')>0?'<a href=\"mailto:\\0\">\\0</a>':'\\0'))"
),
$text
);
}
I added already the following functions to my Javascript library to make replaceAll
available. 我已经在Javascript库中添加了以下函数,以使replaceAll
可用。
String.prototype.replaceAll = function(search, replace)
{
if(!replace)
return this;
return this.replace(new RegExp(escapeRegExp(search), 'g'), replace);
};
function escapeRegExp(string) {
return string.replace(/([.*+?^=!:${}()|\[\]\/\\])/g, "\\$1");
}
I'm almost sure there is some function like this out there already, but I can't find it. 我几乎可以肯定已经有类似的功能了,但是我找不到。
Thanks, for pointing me in the right direction @waldek_c 谢谢你为我指出正确的方向@waldek_c
However to complete my question, here is the function I took adding the g
parameter at the end of the exp
variable 但是,为了完成我的问题,这是我在exp
变量末尾添加g
参数的函数
function replaceURLWithHTMLLinks(text) {
var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
return text.replace(exp,"<a href='$1'>$1</a>");
}
Thanks to this article: How to replace plain URLs with links? 感谢本文: 如何用链接替换纯URL?
Sorry for not having it found by myself :-) 很抱歉没有自己找到它:-)
