angularjs - controllers using as normal function or array notation -

what difference between these 2: angular.module('myapp' ,[]) .controller('mycontroller', function($scope){...}); and angular.module('myapp' ,[]) .controller('mycontroller, ['$scope', function($scope){...})]; this quite complicated new angularjs me. syntax different java , c. many thanks. there's nothing difference between them. both code works same way. if use first code , when minify code confuse. look example: .controller('mycontroller', function(a){...});//$scope changed and code won't work angularjs code uses $scope variable doesn't take first, second, third, , on parameters. so, second code safer first if when minify code, still takes same variable i.e. $scope. look example: .controller('mycontroller', ['$scope', function(a){...})];//a refers $scope so, above code works fine when minify code $scope injected in place of a. so, if pass multiple parameters ordering matters in ...

autocomplete - Parsley.js - Re-validate a field after selecting an auto-complete value or drag-and-drop -

Image
after parsley validation, error message may displayed near field. if user types corrected value, field automatically re-validated, message disappear, , field marked success. however, if valid value entered either i) selecting field's "auto-complete" dropdown or ii) dragging-and-dropping field, not invoke re-validation, , error message remains though field has valid value. example... q: how force fields re-validate upon selecting value browser's auto-complete dropdown/drag-and-drop? (i realise can specify no auto-complete on fields, may not desirable, , doesn't solve drag-and-drop issue.) in case, use bootstrapvalidator validation. then, have revalidate field after fetching data $('yourform).bootstrapvalidator('revalidatefield', 'inputname');

python - I want my already created virtualenv to have access to system packages -

i've installed opencv3 on ubuntu 14.04. tutorial followed reason using virtualenv. want move opencv virtual global environment. reason can't seem use packages installed on global environment getting on nerves. how can that? i'm not sure got question right, probably virtualenv has been created without specifying option --system-site-packages , gives virtualenv access packages installed system-wise. if run virtualenv --system-site-packages tutorial_venv instead of virtualenv tutorial_venv when creating tutorial virtualenv, might fine. fyi, using virtualenv local dependencies it's widespread practice, which: gives isolation , reproducibility in production scenarios makes possible users without privilege of installing packages system-wide run , develop python application the last benefit might reason why tutorial suggested virtualenv based approach.
