Replace double backslashes with a single backslash in javascript
提问by Guido Visser
I have the following problem:
我有以下问题：
I have a script that executes an AJAX request to a server, the server returns C:\backup\in the preview. However, the response is "C:\\backup\\". Not really a big deal, since I just thought to replace the double slashes with single ones. I've been looking around here on stack, but I could only find how to replace single backslashes with double ones, but I need it the other way around.
我有一个向服务器执行 AJAX 请求的脚本，服务器C:\backup\在预览中返回。然而，回应是"C:\\backup\\"。没什么大不了的，因为我只是想用单斜线代替双斜线。我一直在堆栈上四处寻找，但我只能找到如何用双反斜杠替换单反斜杠，但我需要反过来。
Can someone help me on this matter?
有人可以帮我解决这个问题吗？

This should do it: "C:\\backup\\".replace(/\\\\/g, '\\')
这应该这样做： "C:\\backup\\".replace(/\\\\/g, '\\')
In the regular expression, a single \must be escaped to \\, and in the replacement \also.
在正则表达式中，单个\必须转义为\\，并且在替换中\也必须转义。

Best is to use regex to replace all occurrences:
最好是使用正则表达式来替换所有出现的：
C:\backup\".replace(/\/\//g, "/")
this returns: C:\backup\
这将返回： C:\backup\
OR
或者
use split()
使用 split()
"C:\backup\".split();
both produces your desired result
两者都会产生您想要的结果
C:\backup\
C:\备份\
console.log("using \"C:\backup\\".replace(/\/\//g, \"/\")")
console.log("C:\backup\".replace(/\/\//g, "/"));
console.log("Using \"C:\backup\\".split()");
console.log("C:\backup\".split());
