问题 I'm writing a script for a signature function in a forum program and any time someone puts a quote or some other JavaScript parse-able character into it, it breaks my program. Is there a way either to force JavaScript to recognize it as a string without parsing it as script or, failing that, a function that escapes all scripting within a string that will be dynamic? I did a search and all I could find were endless webpages on how to escape individual characters with a slash - perhaps my

问题 I have an assignment to create a lexical analyser and I've got everything working except for one bit. I need to create a string that will accept a new line, and the string is delimited by double quotes. The string accepts any number, letter, some specified punctuation, backslashes and double quotes within the delimiters. I can't seem to figure out how to escape a new line character. Is there a certain way of escaping characters like new line and tab? Here's some of my code that might help <

问题 I have a very peculiar case. My ASP.NET page calls a stored procedure of ours that performs a Full-Text Search query on our database. Some of the commonly searched strings include an ampersand because a few brands of our products (well-known brands, too) have an & in their name. It turns out that in a certain case I get no results unless I escape the ampersand ( \& ), and in a certain other case I get no results only if I escape the ampersand . I don't know if this is relevant, but (without

问题 I'm trying to emulate Oracle's RTRIM(expression, characters) in MsSql Server 2008 R2 with the following query: REVERSE( SUBSTRING( REVERSE(field), PATINDEX('%[^chars]%', REVERSE(field)), LEN(field) - PATINDEX('%[^chars]%', REVERSE(field)) + 1 ) ) The problem is that I want to be able to trim characters like ] and ^ which do probably need escaping. I don't know how to do this. Things like \] don't work. I'm aware of the ESCAPE clause but I do not understand exactly how it works and, by the way

问题 I'd like to escape ":" and/or "=" as the name in a configuration file. Does anyone know how to achieve this? I try backslash "\", it does not work. 回答1: If you're using Python 3, you don't need to. Look at the Python docs section on Customizing Parser Behavior. By default, configparser uses ":" and "=" as delimiters, but you can specify different delimiters when you create the configparser object: import configparser parser = configparser.ConfigParser(delimiters=('?', '*')) In this example,

问题 I need to write an argument to a file in a Bash script, so I'm doing something like this, echo "Argument is: $1" >> file The problem is that if there's a tilde (~) in the argument I don't want it expanded to the home directory. So if the user passed ~/bin as an argument to the script, it would get written as ~/bin and not /home/user/bin. How do I do this? 回答1: I assume your program is started as: $ your_prog ~/foo The argument is translated before your program is even started, so there's
