带有“$”的字符串在Javascript中没有给出预期的输出

Question

I have a string "$$$$$1.00" Need to replace all '$' with empty string. I don't know the exact number of '$' as I fetch it from server.

I tried using

"$$$$$1.00".replace(/$/g, "")

which is not working out.

I know I can run through the loop and remove it. Is there any way to do that. Also, why it is not working ?

It is working in this case

I have added the JSfiddle link for the simple executable JSFiddle

Answer 1

You need to escape the dollar sign ( $ ) in the RegExp as this means the end of the string in RegExp world.

Refactor to:

"$$$$$1.00".replace(/\$/g, "")

Answer 2

既然你要全部更换，你应该使用/\\$+/匹配1或更多的人，并确保你逃避$用\\$以文本字符串“$”匹配

"$$$$$1.00".replace(/\$+/, "")
