javascript replace characters
提问by mustapha george
I want to replace all occurent of "-", ":" characters and spaces from a string that appears in this format:
我想从以这种格式出现的字符串中替换所有出现的“-”、“：”字符和空格：
"YYYY-MM-DD HH:MM:SS"
something like:
就像是：
var date = this.value.replace(/:-/g, "");
回答by Gabi Purcaru
You were close: "YYYY-MM-DD HH:MM:SS".replace(/:|-/g, "")
你很接近： "YYYY-MM-DD HH:MM:SS".replace(/:|-/g, "")
回答by Rocket Hazmat
/:-/gmeans ":" followed by "-". If you put the characters in []it means ":" or "-".
/:-/g是指":" followed by "-"。如果您将字符放入其中，[]则表示":" or "-".
var date = this.value.replace(/[:-]/g, "");
If you want to remove spaces, add \sto the regex.
如果要删除空格，请添加\s到正则表达式。
var date = this.value.replace(/[\s:-]/g, "");

The regex you want is probably:
您想要的正则表达式可能是：
/[\s:-]/g
Example of usage:
用法示例：
"YYY-MM-DD HH:MM:SS".replace(/[\s:-]/g, '');
[]blocks match any of the contained characters.
[]块匹配任何包含的字符。
Within it I added the \spattern that matches space characters such as a space and a tab \t(not sure if you want tabs and newlines, so i went with tabs and skipped newlines).
在其中，我添加了\s匹配空格字符的模式，例如空格和制表符\t（不确定是否需要制表符和换行符，所以我使用制表符并跳过了换行符）。
It seems you already guessed that you want the global match which allows the regex to keep replacing matches it finds.
似乎您已经猜到您想要global 匹配，它允许正则表达式不断替换它找到的匹配。

You can use either a character class or an |(or):
您可以使用字符类或|（或）：
var date = "YYYY-MM-DD HH:MM:SS".replace(/[:-\s]/g, '');
var date = "YYYY-MM-DD HH:MM:SS".replace(/:|-|\s/g, '');
