You're looking for an equivilent of PHP's br2nl(). This should do the job:
您正在寻找与 PHP 相同的br2nl(). 这应该可以完成这项工作：
function br2nl(str) {
return str.replace(/<br\s*\/?>/mg,"\n");
}

A cheap function:
一个便宜的功能：

}

vat str = "Hello<br \>world!";
var result = brToNewLine(str);

This function considers whether to remove or replace the tags such as <br>, <BR>, <br />, </br>.
该函数考虑是否删除或替换诸如<br>、<BR>、<br />、等标签</br>。
/**
* This function inverses text from PHP's nl2br() with default parameters.
*
* @param {string} str Input text
* @param {boolean} replaceMode Use replace instead of insert
* @return {string} Filtered text
*/
function br2nl (str, replaceMode) {
var replaceStr = (replaceMode) ? "\n" : '';
// Includes <br>, <BR>, <br />, </br>
return str.replace(/<\s*\/?br\s*[\/]?>/gi, replaceStr);
}
In your case, you need to use replaceMode. For eaxmple: br2nl('1st<br>2st', true)
在您的情况下，您需要使用replaceMode. 例如：br2nl('1st<br>2st', true)
