spaces

问题 I have the following query. I'm trying to find values of 'hello world', but it returns zero results. However, when value = 'hello*' , it does give me that expected result. Any idea how I can change my query to give me that hello world result? I've tried *hello world* , but for some reason it just won't search anything with spaces. I think it has something to do with the spaces as when I try to search "* *" , it gives me no results. But I know I have many values in there with spaces. Any ideas

问题 Is it possible to open files that are indented with 2 spaces, but show me 4 space indentation, and when I make 4 spaces, it saves in a 2 space format? Edit It turns out I also need to be able to ensure that it works if the file has a mix of tabs, 2 spaces, and 4 spaces. Edit 2 So, here is my current solution. I'm having to remap my (originally mapped to :w) so that I can place my cursor back where it was (and give me one "history back" as far as cursor positions when I do a save. Is there a

问题 I want to remove the excess white spaces using VB.net ex. "The Quick Brown Fox" I want output "The Quick Brown Fox" Thanks, inchika 回答1: You can use a simple regular expression for that: Dim cleaned As String = Regex.Replace(input, "\s{2,}", " ") 回答2: I realize that this question is fairly old, but there is another option that doesn't involve Regex, or manually looping through the string and replacing: Private Function StripSpaces(input As String) As String Return String.Join(" ", input.Split

问题 <textarea rows='5' cols='50' id='content'></textarea> <input type='button' value='Extract Text' onclick='someFunction()'/> Assume these two html elements. My problem is the following: Let's say that the user enters into the textarea field something like this, exactly as typed. With all line breaks and spaces. (And yes, this is Python :P) if (...): print "Hello everyone!" else: print "Dudes help me out!" My objective is to make a JavaScript function which removes all the spaces and line breaks

问题 This may be a total beginner's question, but I have yet to find an answer that works for me. Currently, I'm writing a program for a class that takes in a user's input (which can be one or more numbers separated by spaces), then determines whether the number is prime, perfect, or neither. If the number is perfect, then it will display the divisors. Thus far, I've already written the code for the prime, perfect, and listing the divisors. I'm stuck on the input portion of my program. I don't

问题 Currently I have this code which replaces any double space with a <br /> . It works as expected: <tr class="' . ($counter++ % 2 ? "odd" : "even") . '"> <td>Garments:</td> <td>' . str_replace(' ', '<br /><br />', trim($result['garment_type'] ) ) . '</td> </tr> However I want to do another str_replace() on the same line to replace any single spaces with a pipe character | . I tried duplicating the code but that just creates another TD for me. Any help would be appreciated. 回答1: The order of the

问题 In Python, is there a mean to enforce the use of spaces or tabs indentation with a per file basis ? Well, perhaps "enforce" is too strong, more like a "recommendation". I keep receiving patch files with mixed indentation and this is annoying... (to say the least) Python itself can tell when there is a problem, but I am searching something to do that at the editor level, like it exists for the charset. Edit : Ok, my question wasn't clear, I am asking this because I keep receiving corrections
