is possible when click button addclass on html page using jquery ? for example, a.html <button class="btn_click">when click, add 'active' class on b.html</button> b.html <div class="active">active</div> is possible? without server side intermediary wouldn't possible. you'd need send results of button click server update value , either pushed there page or other page poll , ask changes. think of way. in facebook, if you're on 2 different computers , send message someone, message sent shows on other computer also. there servers involved. but send directly? no. suppose might possible if 2 pages or tabs in same browser on same computer , used browser plugin. otherwise, there huge security risks if possible way.

i have following simple test test_f(mytest, outputcomparetest) { capturestderr(); capturestdout(); std::string actualoutput = testing::internal::getcapturedstdout(); std::string matchingsample = "some string compare output"; expect_eq(actualoutput, matchingsample); expect_eq(getcapturedstderr(), ""); } the question here have release/delete captured buffer in order not keep forever , other test can recapture output without problem. i have been looking in googletest docs seems there not predefined function releases captured buffer capturestderr() , capturestdout(). mean lifetime of objects limited lifetime of test? may have missed not indicated in documentation. partially indicated fact can't assign pointer it. std::string* actualoutput = &testing::internal::getcapturedstdout(); ... delete actualoutput; actualoutput = nullptr; because getcapturedstdout seems me non lvalue. want sure don't have delete , if how it.

i have following default 5 if there not value json_element['limit'] : json_element['limit'] = 500 limit ||= json_element['limit'].to_i limit ||= 5 this current implementation, seems 1 line long. as amndan says, idea here order things in order of precedence, highest lowest, left right, speaking: def do_thing(limit_override) limit ||= limit_override || input || default end in case you're testing hash property , converting integer, have options: limit ||= json_element['limit'] ? json_element['limit'].to_i : 5 or to_i whatever if it's ever less efficient: limit ||= (json_element['limit'] || 5).to_i

this question has answer here: adding 2 java 8 streams, or element stream 7 answers i trying integers, getting on stream, however, being added new stream of integers using later on. to populate new stream of integers, make multiple intstreams , append them new 1 using intstream builder, such: is there better way approach this: intstream rightside = intstream.range(8, this.rows.getslotamount()).map(value -> value + 9); intstream leftside = intstream.range(0, this.rows.getslotamount()).map(value -> value % 9); intstream top = intstream.range(0, 9); intstream bottom = intstream.range(this.rows.getslotamount() - 9, this.rows.getslotamount()); intstream.builder slots = intstream.builder(); rightside.foreach(slots::add); leftside.foreach(slots::add); top.foreach(slots::add); bottom.foreach(slots::add); slots.build().fo...

what difference between search() , match() functions in python re module ? i've read documentation ( current documentation ), never seem remember it. keep having , re-learn it. i'm hoping answer examples (perhaps) stick in head. or @ least i'll have better place return question , take less time re-learn it. re.match anchored @ beginning of string. has nothing newlines, not same using ^ in pattern. as re.match documentation says: if 0 or more characters @ beginning of string match regular expression pattern, return corresponding matchobject instance. return none if string not match pattern; note different zero-length match. note: if want locate match anywhere in string, use search() instead. re.search searches entire string, the documentation says : scan through string looking location regular expression pattern produces match, , return corresponding matchobject instance. return none if no position i...
