javascript - How to test $element in AngularJS controller using Karma? -

-

i having problem have controller in app use <div ng-controller='logbookeditctrl'> </div> , controller has $element provider in need modify element.

describe('logbookeditctrl', function(){   'use strict';    beforeeach(module('logbooks.edit'));     it('should create "logbook" model', inject(function($controller) {     var scope = {},     ctrl = $controller('logbookeditctrl', {$scope: scope}); //this explodes because says $element provider not found, because there no html element of course..the controller being created on own.     }));  });

i have tried following, again says $element provider not found :

beforeeach(inject(function(_$element_) {   var element = compile('<div></div>');   $element = element; }));

you need pass dependency itself, since refers bound element of controller. , there no $element provider available in angular (much similar $scope these dynamic special dependencies provided app injector). create element object using angular.element , pass in locals controller constructor,something this.

var scope = {},      element = angular.element('<div></div>'); //provide element want test  ctrl = $controller('logbookeditctrl', {$scope: scope, $element:element });

this opens fact why not recommended use $element inside controller , perform dom operation in them.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
