Use this regular expression to match square brackets or single quotes:

使用此正则表达式匹配方括号或单引号:

/[\[\]']+/g

Replace with the empty string.

替换为空字符串。

"['abc','xyz']".replace(/[\[\]']+/g,'')

here you go

干得好

var str = "['abc',['def','ghi'],'jkl']";
//'[\'abc\',[\'def\',\'ghi\'],\'jkl\']'
str.replace(/[\[\]']/g,'' );
//'abc,def,ghi,jkl'

回答by Greg Hewgill

You probably don't even need string substitution for that. If your original string is JSON, try:

您可能甚至不需要字符串替换。如果您的原始字符串是 JSON,请尝试:

js> a="['abc','xyz']"
['abc','xyz']
js> eval(a).join(",")
abc,xyz

Be careful with eval, of course.

eval当然要小心。
