仅从字符串的开头和结尾替换或删除字符串中的某些特殊字符，而不是从javascript的字符串中间

Question

replace or remove some special characters (-) in string only from starting and ending , not from in between of string in javascript.

the string is fully dynamic , count of special characters (-) at starting and ending will be different every time , and the string will also change every time , so we have to develop dynamic logic.

ex.

original string = "-----hello--stack--over--flowj-----"
output string = "hello--stack--over--flowj"

I have tried replace and substring methods , but i was unable to remove specifically starting and ending special character (-) , and for that I was thinking for loops and to count special characters (-) and that all.

Thank You.

您正在寻找replace()函数：

string.replace(/^-*|-*$/g,"")
