removing-whitespace

问题 The question and answers have custom defined div wrappers around them. The closing div is on next line producing a blank line. I want to remove that line. Post Link http://fgstudy.com/uncategorized/a/ I already tried the white-space CSS code CSS Code: div#q1, div#a1, div#a2 { white-space: normal; } P { white-space: normal;} HTML CODE: <hr><div id="q1"><p>Which of the following the highest hydration energy</p> </div><div id="a1"><p>Mg⁺⁺</p> </div><div id="a2"><p>Li⁺</p> <

问题 I am using this function to build a pig latin translator and seem to have everything figured out except for the .trim() part. What should I do different? function ParseText() { var myText = "asdf\n hat\n cat dog\n apple"; var lines = myText.split("\n"); var results = ""; for (var i = 0, len = lines.length; i < len; i++) { lines[i].trim(); var words = lines[i].split(" "); for (var j = 0, lenght = words.length; j < lenght; j++) { var word = words[j]; if (word.charAt(0) == "a" || word.charAt(0)

问题 Is there a way to this kind of minification with javascript and update the DOM (clientSide) Input: <div class="parentDiv"> <div class="childDiv">Some text</div> <div class="childDiv">Some text</div> </div> Output: <div class="parentDiv"><div class="childDiv">Some text</div><div class="childDiv">Some text</div></div> I know its useless doing the minification after downloading all the content. The point here is to stop the identation to create gaps between my divs. I know that if I put a

问题 I'm using awk '{gsub(/^[ \t]+|[ \t]+$/,""); print;}' in.txt > out.txt to remove both leading and trailing whitespaces. The problem is the output file actually has trailing whitespaces! All lines are of the same length - they are right padded with spaces. What am I missing? UPDATE 1 The problem is probably due to the the fact that the trailing spaces are nor "normal" spaces but \x20 characters (DC4). UPDATE 2 I used gsub (/'[[:cntrl:]]|[[:space:]]|\x20/,"") an it worked. Two strange things:

问题 The overhead in looping through the string and replacing double spaces with single ones is taking too much time. Is a faster way of trying to replace multi spacing in strings with a single whitespace? I've been doing it like this, but it's just way too long and wasteful: str1 = "This is a foo bar sentence with crazy spaces that irritates my program " def despace(sentence): while " " in sentence: sentence = sentence.replace(" "," ") return sentence print despace(str1) 回答1: look at this In [1]:

问题 I want to search-replace something containing whitespace on a bash command line, and I assumed sed would be the easiest way to go. Using [ \t] denoting either tab or space, to match the whitespace, works as intended: echo "abc xyz" | sed "s/[ \t]xyz/123/" abc123 But using \s instead of [ \t] does not, to my surprise: echo "abc xyz" | sed "s/\sxyz/123/" abc xyz I'm fairly new to bash so I might be missing something trivial, but no matter what I do, I can't get this to work. Using \\s instead
