javascript - jQuery scrolling text on hover -


i have "a" element want scroll left on hover. remove first character , append end of string.

how can continuously fire scroll function?

mouse enters element -> scroll() fired until mouse leaves element or user clicks on it.

html:

<a href="foo.htm" class="scrollthis">this text scrolls on hover</a>

jquery:

$(".scrollthis").hover(function(){ scroll($(this)); }); function scroll(ele){ var s = $(ele).text().substr(1)+$(ele).text().substr(0,1); $(ele).text(s); }

use setinterval() call repeatedly mouseenter, clearinterval() stop on mouseleave:

var intervalid; $(".scrollthis").hover(function(){ var $this = $(this); intervalid = setinterval(function() { scroll($this); }, 100); }, function() { clearinterval(intervalid); });

note don't need use $(ele) in scroll() function because ele jquery object:

function scroll(ele){ var s = ele.text().substr(1)+ele.text().substr(0,1); ele.text(s); }

demo: http://jsfiddle.net/htbzn/

you can make scroll() function bit neater if use callback syntax of .text() method (or move 1 line directly .hover code):

function scroll(ele){ ele.text(function(i,val) { return val.substr(1) + val.substr(0,1); }); }​

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
