ampersand

问题 I have a slight problem in that the string I'm reading from a cookie is broken after the ampersand. So for example the string "hello & world" would just display "hello ". It is a string that is a short code, and converted to something more meaningful using a switch function, and then displayed within a text box. The switch function works fine, but obviously if it is not reading the full string from the cookie in the first place, then it won't be able to locate the short code within the switch

问题 I've got the following code (this is WordPress function) (example of wrong structure): <?php paginate_comments_links('prev_text=← Older&next_text=Newer →'); ?> Example of correct structure: <?php paginate_comments_links('prev_text=Older&next_text=Newer'); ?> As you can see I'm trying to add preceding arrow + space ( ←  ) to 'Older' word and space + arrow (  → ) to 'Newer' word. The problem is that there is a conflict between & that separates 2 function arguments and & that is the beginning of

问题 I have a problem I'm struggling with. I have this mixin (which is an attempt to port some less to sass ): @mixin button-variant($color, $background, $border) { ... .foreverAlone{ ... } .iThink .illNeverWork& { color: $pinkUnicornRainbow; ... } } Which obviously is not working :D I would like it to generate something like: .callerClass .foreverAlone{ ... } .callerClass .iThink .illNeverWork.callerClass{ color: #123ABC; ... } The mixin is called inside various div classes, so it is not possible

问题 I have a .sh that is reading in lines from a .txt to be used as parameters for another shell script.Every two lines process in parallel.

问题 The following is an excerpt from my C++ text, illustrating the syntax for declaring a class with a copy constructor. class Student { int no; char* grade; public: Student(); Student(int, const char*); Student(const Student&); ~Student(); void display() const; }; The copy constructor, as shown here: Student(const Student&); Has an ampersand after the parameter Student. In C, and C++ as-well I believe, the ampersand character is used as a 'address of' operator for pointers. Of course, it is

问题 This question already has answers here : ampersand (&) at the end of variable etc (5 answers) Closed 5 months ago . I am fairly new to programming. I am just moving on to C++ from C in my college courses, and I encountered something that I haven't seen before in C. Sometimes after the type, either in a function declaration or passing a parameter, a & immediately follows the type. For example, we use a struct called Customer in one of our projects, and some of the functions pass Customer& .

问题 I am trying to parse the ampersand value in a PHP string. It keeps returning blank values after I run my code and I am sure it is because of the 'ampersand' value in my variable ($area). I tried htmlspecialchars, html_entity_decode but to no avail. Please see code below: <?php /** Create HTTP POST */ $accomm = 'ACCOMM'; $state = ''; $city = 'Ballan'; $area = 'Daylesford & Macedon Ranges'; $page = '10'; $seek = '<parameters> <row><param>SUBURB_OR_CITY</param><value>'. $city .'</value></row>

问题 I'm developing a ribbon tab for use in a template ( MyTemplate.dotm ) for Word 2010. My problem: I want to have an ampersand symbol (&) in the label for a group. I have tried many things, and also alot of googling about this issue, but nothing works: (named) & (decimal) & (decimal) & (hex) & This is what I have tried, the xml saved in MyTemplate.dotm -file (with Custom UI Editor for Microsoft Office ): <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <customUI xmlns="http://schemas

问题 I want to restrict usage of unescaped ampersands in a particular input field. I'm having trouble getting a RegEx to kill usage of "&" unless followed by "amp;"...or perhaps just restrict usage of "& " (note the space). I tried to adapt the answer in this thread, but to no avail. Thanks. (FWIW, here's a RegEx I made to ensure that a filename field didn't contain restrited chars. and ended in .mp3. It works fine, but does it look efficient?) ^[^&,<,>,:,",/,\\,|,?,\*]+(\.mp3|\.MP3|\.Mp3|\.mP3)$
