Javascript：匹配所有“\r\n”的正则表达式，把换行符替换成 br

Javascript：匹配所有“\r\n”的正则表达式，把换行符替换成

var atStr="字符串";var dataAt=atStr.replace(/(\r\n)|(\n)/g,'<br>');return "<p class='text-left pl-10 pr-10'>堆栈信息<br>"+dataAt+"</p>";

代码如下：

<script>    function atStr () {    var atStr="at aasdfasdfa,\r\n at asdfsdfasdlfkl;afafat，aasdfasdfa,\r\n at asdfsdfasdlfkl;afafataasdfasdfa,\r\n at asdfsdfasdlfkl;afafataasdfasdfa,\r\n at asdfsdfasdlfkl;afafataasdfasdfa,\r\n at asdfsdfasdlfkl;afafat";    var dataAt=atStr.replace(/(\r\n)|(\n)/g,'<br>');    return dataAt;    }    document.write(atStr())</script>

显示效果如下：

at aasdfasdfa,at asdfsdfasdlfkl;afafat，aasdfasdfa,at asdfsdfasdlfkl;afafataasdfasdfa,at asdfsdfasdlfkl;afafataasdfasdfa,at asdfsdfasdlfkl;afafataasdfasdfa,at asdfsdfasdlfkl;afafat
