Javascript .replace（）替换所有出现的/

Question

如果我有一个包含</custom-tag>的字符串，我如何使用replace来查找字符串中所有出现的标记，并将其替换为“”，例如mystr.replace(/</constant>/g,"")不起作用。

Answer 1

You need to escape the / so that it isn't interpreted as the end of the regex.

mystr.replace(/<\/constant>/g, "")

Of course, if your search is a constant expression, as it is here, you can use the following technique to perform a global replace without regular expressions:

mystr.split("</constant>").join("")

Answer 2

mystr.replace(/<\/constant>/g,"");

这应该做到这一点
