正则表达式分裂问题

Question

我有

的javascript字符串变量

var sttr="We prefer questions that can be answered --------------------- not just discussed ---------------------
Provide details ---------------------------- Write clearly and simply --------------------------answer all the question"

请建议如何在短划线的基础上将字符串拆分为句子数组（-----）使用正则表达式

结果应该是

array[0]=We prefer questions that can be answered
array[1]=not just discussed
array[2]=Provide details
array[3]=rite clearly and simply
array[4]=answer all the question

注意：每个句子介于10到50之间的短划线（-----）范围

Answer 1

您希望拆分/-{10,50}/g。

Answer 2

sttr.split（/ - + /克）;

使用regular expression tester
