<div (ng-repeat='item in items') > {{item.name}} //works {{item["name"]}} // works </div> how repeat item[property] dynamically without using ".name" or ['name']? to dynamically go through properties, you're going need call object.keys(item) , iterate through them. it's best prune data within controller, minimize finagling you'll need within html. if want try within html-angular structures, define: $scope.returnallkeyvalues = function(obj){ var x = object.keys(obj), arr = []; for(var = 0; i<x.length; i++){ arr.push(obj[x[i]]); } return arr; } what function takes in json object, parses through , collects values every key within it. then, within html, can write this: <h3>fifa mactch summary:</h3> <div ng-app ng-controller="myctrl"> <ul> <li ng-repeat="item in items"> <span ng-init=&q

i using javascript:void(window.open('" & url & "','_blank')) open url in new window. i've used many times , works except when url string built using dynamic parameter values. what works : the url trying open on ssrs action below: ssrsserveraddress/headcount.rdl&pbusinessunit=" & fields!businessunit.value & "&pcalendar=" & **code.urlencode**("[monthly calendar].[monthly calendar].[month].&[" & fields!monthyear.value &"]) the ssrs action (go url) expression works when using above url. uses custom code.urlencode (see description below) , passes calendar parameter correctly. what not work: the problem need url open in new window. here's javascript action using: javascript:void(window.open('"ssrsserveraddress/headcount.rdl&pbusinessunit=" & fields!businessunit.value & "&pcalendar=" & code.urlencode("[monthly calendar].[m

on xamarin ios. i'm using httpclient json string. problem ignores updates , gives me same json response if query same url. want not cache , query url , give me new response. this sounds trivial, there must simple way this. i'm using forms shared project. i assume setting cache-control header no-cache? client.defaultrequestheaders.cachecontrol.nocache = true; if still doesn't work - maybe server caching response? if comes down it, can defeat adding cachebuster querystring though. append bogus param , pass unique value each time. example, if url http://my.url.com/resource/someid can defeat caching using http://my.url.com/resource/someid?b=1 , increment "b" param each call.

i trying change commit message in sourcetree cannot find option is. has not been pushed yet. how can amend message older commits in sourcetree or command line? there no feature because how git internally work, sha1 seal each commit. but : do 'amend' if message 1 of last commit. do git rebase -i named rebase interactive , choose 'reword' (or 'r') each commit want rewrite commit message. use git 'notes' join new comment next existing 1 (but handle not straightforward... )

i need convert normalized integer values , real floating-point values. instance, int16_t, value of 1.0 represented 32767 , -1.0 represented -32768. although it's bit tedious each integer type, both signed , unsigned, it's still easy enough write hand. however, want use standard methods whenever possible rather going off , reinventing wheel, i'm looking standard c or c++ header, boost library, or other small, portable, easily-incorporated source performs these conversions. here's templated solution using std::numeric_limits : #include <cstdint> #include <limits> template <typename t> constexpr double normalize (t value) { return value < 0 ? -static_cast<double>(value) / std::numeric_limits<t>::min() : static_cast<double>(value) / std::numeric_limits<t>::max() ; } int main () { // test cases evaluated @ compile time. static_assert(normalize(int16_t(32767)) == 1, ""); static_asse

in company i'm working @ develop on windows, visual studio, , cross compile linux using eclipse. our final application runs on linux. i'm trying convince them how easy , fast build on linux instead of using old cross compiler , having sort of weird bugs. of bugs vanish when compile them later versions of gcc on linux. since cross compiler old cannot use c++11 features. one major problem have since our projects developed on windows i'm having hard time formatting headers! example assume have folder named io header file demo.h in it. this #include <io\demo.h> works fine on windows. on linux doesn't because windows not case sensitive , both \ , / work on windows. on linux must this #include <io/demo.h> otherwise error can't find specified header file. have more 20 main project working on , each 1 around 3-4 gb. i've modified 1 of them. took me around 7 hours it. are there tools me make transition faster? our source code 95% c++ ,

i made server , client java application. should communicate each other through tcp sockets threads. used inputstreamreader , bufferedreader read message, , used outputstreamwriter , bufferedwriter write message. object of bufferedreader called reader, , object of bufferedwriter called writer. after playing around that, realized socket becomes irresponsive if writer closed. i closed writer on server side because never send message, read message client only. not throw exception, stuck called methods relate socket such reader.readline() , socket.setsotimeout(). the problem easy solve since don't close writer. however, curious why socket being unable communicate. the socket becomes irresponsive if writer closed the socket becomes closed if writer closed. i closed writer on server side because never send message, non sequitur. if don't need writer , don't construct it. stuck called methods relate socket such reader.readline() , socket.set

basically have html table 3 layers of expand/collapse functionality. seeking achieve have layers expand/collapse underneath parents instead of right, become downward slope once expanded. here jsfiddle: https://jsfiddle.net/htflmekl/1/ //expand collapse based on parent class column 1 $(document).ready(function() { $('.parent').prepend('-'); $('.parent').on('click', function() { if ($(this).text().indexof('-') != -1) { var str0 = $(this).text().replace(/-/g, '+'); $(this).text(str0); } else { var str = $(this).text().replace(/\+/g, '-'); $(this).text(str); } var $row = $(this).parent(); var rowspan = +$(this).attr('rowspan') || 4; $.merge($row, $row.nextall()).slice(0, rowspan).find('.alliance').toggle(); $.merge($row, $row.nextall()).slice(0, rowspan).find('.race').toggle(); $.merge($row, $row.nextall()).slice(0, rowspan).find('.role
