Try this
var str="<p>fhgfhgfhgfh</p><br><br><p>ghgfhfgh</p><br><br><p>";
var n=str.replace(/<br><br>/g,"<br>");
console.log(n);
Working DEMO
Edit: Above works for 2 br tags, code below should take care of any number of br tags.
编辑:以上代码适用于2个br标签,下面的代码应该处理任意数量的br标签。
var n = str.replace(/(<br>)+/g, '<br>');
Working DEMO
where /.../ denotes a regular expression, (<br>) denotes <br> tag, and + denotes one or more occurrence of the previous expression and finally g is for global replacement.
其中/.../表示正则表达式,(
)表示
标签,+表示前一个表达式的一个或多个出现,最后g表示全局替换。

This should do the trick:
这应该是诀窍:
str.replace(/(?:<br>){2,}/g, '<br>')
Or, if they can be on different lines:
或者,如果他们可以在不同的行:
str.replace(/(?:<br>\s*){2,}/g, '<br>')
