问题 Executing the following SQL: drop function f go in MS Sql Server Management Studio give me this parse error: Msg 102, Level 15, State 1, Line 1 Incorrect syntax near 'go'. Why? If I open a new tab and copy/paste the SQL into it, it also fails. But If I open a new tab and retype the SQL entirely, it works fine. 回答1: SQL Server Management Studio can't handle some non printable characters. Check the newline characters, probably you have Linux (LF) or Mac style (CR) instead of Windows style (CR

问题 I have some javascript that manipulates html based on what the user has selected. For real browsers the methods I'm using leverage the "Range" object, obtained as such: var sel = window.getSelection(); var range = sel.getRangeAt(0); var content = range.toString(); The content variable contains all the selected text, which works fine. However I'm finding that I cannot detect the newlines in the resulting string. For example: Selected text is: abc def ghi range.toString() evaluates to

问题 I'm using CSS (via JQuery , but not relevant to this question) to highlight certain elements within an HTML file: I'm using "pre" tags to separate out logical elements in my file, but I noticed that "pre" tags seem to leave newlines between elements. Can I get rid of these using CSS ? (Or what shall I use instead of "pre" tags? The text elements may contain HTML elements themeselves : which should not be rendered, and should be shown literally as source-code: hence my initial choice with "pre

问题 I need to post multi-line data via a hidden field. The data will be viewed in a textarea after post. How can I post a newline/carriage return in the html form? I've tried \r\n but that just posts the actual "\r\n" data <input type="hidden" name="multiline_data" value="line one\r\nline two" /> Is there a way to do this? 回答1: Depends on the character set really but should be linefeed and should be carriage return. You should be able to use those in the value attribute. 回答2: Instead of using

问题 How print format string passed as argument ? example.cpp: #include <iostream> int main(int ac, char* av[]) { printf(av[1],"anything"); return 0; } try: example.exe "print this\non newline" output is: print this\non newline instead I want: print this on newline 回答1: No, do not do that! That is a very severe vulnerability. You should never accept format strings as input. If you would like to print a newline whenever you see a "\n", a better approach would be: #include <iostream> #include

问题 Certain fields in our mysql db appear to contain newline characters so that if I SELECT on them something like the following will be returned for a single SQL call: Life to be sure is nothing much to lose But young men think it is and we were young If I want to preserve the line breaks when displaying this field on a webpage, is the standard solution to write a script to replace '\n\r' with a br HTML tag or is there a better way? Thanks! 回答1: Assuming PHP here... nl2br() adds in <br /> for

问题 I'd like to echo something to a file that contains new line escape sequences, however I would like them to remain escaped. I'm looking for basically the opposite to this question. echo "part1\npart2" >> file I would like to look like this in the file $ cat file old part1\npart2 but it looks like $ cat file old part1 part2 回答1: This is a good example of why POSIX recommends using printf instead of echo (see here, under "application usage"): you don't know what you get with echo . You could get

问题 I never need the ending newline I get from gets . Half of the time I forget to chomp it and it is a pain in the.... Why is it there? 回答1: Like puts (which sounds similar), it is designed to work with lines, using the \n character. gets takes an optional argument that is used for "splitting" the input (or "just reading till it arrives). It defaults to the special global variable $/ , which contains a \n by default. gets is a pretty generic method for readings streams and includes this

问题 jQuery - How do you convert <br> and <br /> and <p /> and such to new line? Does jQuery have a built in br2nl() function - this is for converting new lines tags to user-friendly textfield versions. 回答1: You could create a function like this: jQuery.fn.nl2br = function(){ return this.each(function(){ jQuery(this).val().replace(/(<br>)|(<br \/>)|(<p>)|(<\/p>)/g, "\r\n"); }); }; And use it like any of these ways: $(':input').nl2br(); $('textarea').nl2br(); $('#textarea_id').nl2br(); 回答2: If you
