正则表达式将文本替换为@中的文本

Question

I have some simple regex that should replace @Username to

<a href="http://google.com">@Username</a>

Though its getting very odd results.

REGEX

var msg="@Mr.EasyBB";
msg.replace(/@(.+?)/g,
'<a href=\"http://'+window.location.host+'/u=$1\">$1</a>');

can someone help with this small issue results look like this

<a href="http://google.com">@U</a>sername

Answer 1

.+? is lazy matching - this will match as few characters as it can.

Try this. It will match as many non-whitespace characters as it can.

/@(\S+)/

Answer 2

试试这个：

msg = msg.replace(/@(\S+)/g, '<a href=\"http://'+window.location.host+'/u=$1\">@$1</a>');
