Javascript正则表达式不匹配 [英] Javascript Regular Expression not matching

问题描述

早上全部

我有一个javascript正则表达式无法正常工作，我不知道为什么。

I have a javascript regular expression that doesn't work correctly and I'm not sure why.

我在 https://uptimerobot.com 上调用API，并返回一个JSON字符串监视器雕像的详细信息。然而，这包含在函数调用语法中。像这样：

I'm calling the API at https://uptimerobot.com, and getting back a JSON string with details of the monitor statues. This is however wrapped in a function call syntax. Like this:

jsonUptimeRobotApi({MASKED-STATUES-OBJ})

由于此调用是从通用脚本调用的，我希望测试响应以查看是否有这种类型的语法包装，然后相应地解析它。

As this call is being made from a generic script I was hoping to test the response to see if it had this type of syntax wrapping then parse it accordingly.

但是我似乎找不到与逻辑匹配的RegEx语法：

However I can't seem to find a RegEx syntax to match the logic:

• 字符串开头


• 未知数量的字符[a-zA-Z]


• 打开括号


• 张开大括号


• 任何字符的未知数字


• 关闭大括号


• 关闭括号


• 字符串结尾

• Start of string
• An unknown number of characters [a-zA-Z]
• Open parentheses
• Open brace
• An unknown number of any character
• Close brace
• Close parentheses
• End of string

这看起来是正确的：

^[a-zA-Z]+\(\{.*\}\)$

适用于regex101： https：// regex101。 com / r / sE7dM6 / 1

And works in regex101: https://regex101.com/r/sE7dM6/1

但是我的代码和jsFiddle失败了： https://jsfiddle.net/po49pww3/1/

However it fails in my code and via jsFiddle: https://jsfiddle.net/po49pww3/1/

m是在regex101中添加，因为实际的字符串更长，没有它就无法匹配，但是我尝试过的一些小小的调整没有在jsFiddle中产生匹配。

The "m" was added in regex101 as the actual string is much longer, and failed to match without it, however a number of small tweeks that I've tried havn't resulted in a match in jsFiddle.

任何人都知道什么是错的？

Anyone know whats wrong?

推荐答案

再次逃避所有反斜杠，因为在中分隔符，你必须再次转义反斜杠，否则它将被视为转义序列。

Escape all the backslashes one more time because within " delimiters, you must escape the backslash one more time or otherwise it would be treated as an escape sequence.

var regEx = new RegExp("^[a-zA-Z]+\\(\\{.*\\}\\)$", "m");
