问题 I remember hearing a long time ago that it was considered "best practice" to wrap quotes around font names that contain multiple words in the CSS font-family property, like this: font-family: "Arial Narrow", Arial, Helvetica, sans-serif; For the heck of it, I tried removing the quotes from "Arial Narrow" and Safari and Firefox don't have any problem rendering it. So, is there any logic to this rule of thumb, or is it just a myth? Was it an issue with older browsers that no longer applies to

问题 Is there a default/easy way in Java for split strings, but taking care of quotation marks or other symbols? For example, given this text: There's "a man" that live next door 'in my neighborhood', "and he gets me down..." Obtain: There's a man that live next door in my neighborhood and he gets me down 回答1: Something like this works for your input: String text = "There's \"a man\" that live next door " + "'in my neighborhood', \"and he gets me down...\""; Scanner sc = new Scanner(text); Pattern

问题 I have some string with variable, e.g. string path = @"C:\one\filename.exe" + arguments arguments: "-s -c -d > "somedirectory\some file.txt"" I've problem with redirection output to "somedirectory\some file" If I put "\"" or char.ToString('"') it always interprets as \" ...not alone " How should I put this " character into arguments? 回答1: You need to use \" . The debugger shows it as \" , since it shows valid string literals. However, the actual value in the string is " . (You can see this in

问题 I have this line of code formsParent.innerHTML = "<p style = 'color: black; font-family: "Times New Roman" font-size: 2em'> Order submitted. Thank you for ordering! </p>" The first quote is for the innerHTML property. Next is the properties inside the style attribute of the <p> element, and finally I need another quote inside this for the font-family property with a value that has multiple words so it also needs quotation marks. There are only "" and '' , and using double quotes for the font

问题 Please note that I already had a look at this and that but still cannot solve my problem. Suppose a minimal working example: a <- c(1,2,3) b <- c(2,3,4) c <- c(4,5,6) dftest <- data.frame(a,b,c) foo <- function(x, y, data = data) { data[, c("x","y")] } foo(a, b, data = dftest) Here, the last line obviously returns an Error: undefined columns selected . This error is returned because the columns to be selected are x and y , which are not part of the data frame dftest . Question: How do I need

问题 Sometimes when I use the print function, parentheses and quotation marks appear in the output. I'm using Python 3.4 and writing the code in Sublime Text on a mac. Here's an example Input: a=2 print("a",a) Output: ('a', 2) I'd like to show only a and 2. Thanks in advance! 回答1: You appear to be using Python 2. a = 2 print("a %i" % a) should give you the results you're looking for. Or, using the newer str.format() method: print("a {}".format(a)) In Python 3, your statement print("a",a) will work

问题 I have a huge file to parse. Previously, it was separated by either space or comma and I used sscanf(string, "%lf %lf ", &aa, &bb); to get the data into my program. But now the data format is changed to "122635.670399999","209705.752799999" , with both comma and quotation marks. And I have no idea how to deal with it. Actually, my previous code was found online and I had a really hard time finding a proper document for this kind of problems. It will be great if you can recommend some to me.
