i new angularjs, please tell how use angular.foreach below code for(i=0;i<$scope.data.tabs.length;i++){ $scope.data.tabs[i]['position']=i+1; } you have remember that... the iterator function invoked iterator(value, key, obj) see https://docs.angularjs.org/api/ng/function/angular.foreach angular.foreach($scope.data.tabs, function(tab, i) { tab.position = + 1; }); so here, tab value of $scope.data.tabs[i] , i index of each tab in array.

i have 2 servers: , b. classic asp application deployed on server a. server b contains folder (scanneddocuments). have created shared drive on server point folder. share drive named q:. on ie 7, when try access file using javascript, using: window.open(file://q:/a.txt) it opens file. on ie 8 , above , versions of firefox, not opening. neither error generated nor file opening. i guess getting blocked browser's security features. please let me know how can open files on these browser versions. is there other way open remote file using javascript or using iis? ** edited ** tried creating virtual directory on iis , pointing shared drive. gives error: resource or directory not found. i using iis 7 @anant dabhi right - create simple ajax call server ant return file content. client (js). use instead of window.open(file://q:/a.txt) function getfile(filename) { $.ajax({ url: "/yourweb/file/get", data: { filename: fil

i have following code: const mult = (a, b) => * b; const result = mult(2, 3) + mult(4, 5); const result1 = 6 + mult(4, 5); const result2 = 6 + 20; console.log(result); console.log(result1); console.log(result2); console.log(result === result1 === result2); the expression result === result1 === result2 equates false when result === result1 true , result1 === result2 true. can explain why? it solved left side right, resolving as: (result === result1) === result2; true === result2; for example, event fail: 1 === 1 === 1 it due type conversion not done === operator. following resolves true! 1 == 1 == 1

i new react.js , have heard js library reacts badly modifies it's component structure. there specific procedure add content react elements using jquery. example, if want add content react's div field, can directly use jquery append method insert text div or there other way implement things?. the idea either use traditional approach, or ditch jquery , use react , means using react rendering tree, build tasks, client-side router/spa. you should not modify dom generated react components outside since maintains internal state , virtual dom become out of sync. either use 1 ecosystem or another; 2 different approaches writing website.

a package made of expense, revenue, , balance based on sales made of amount. how add each @sale.amount @package.revenue ? model package.rb: class package < activerecord::base has_many :sales end model sale.rb: class sale < activerecord::base belongs_to :package end routes.rb: rails.application.routes.draw resources :packages resources :sales end end end activerecord has handy sum method calculating sum of values in column: class package < activerecord::base has_many :sales def revenue sales.sum(:amount) end end note while looks similar sales.map(&:amount).sum performance vastly better because activerecord let database calculation , retrieve single value (the final sum) database, whereas other method fetch every associated record database (of there may many thousands), instantiate sale object each one, amount each sale object , calculate sum.

so have category on nsobject called customcategory, following: #import <foundation/foundation.h> @interface nsobject (customcategory) -(bool)dosomething; @end #import "nsobject+customcategory.h" @implementation nsobject (customcategory) -(bool)dosomething { nslog(@"done"); return no; } @end ideally, work on object this: nsobject* object = [nsobject new]; [object dosomething]; however, found works in way no problem: [nsobject dosomething]; so wondering, since instance method have added through category, why works on class? instance methods on nsobject class methods on nsobject. this works because of way objective-c dynamic dispatch. if send message object method implementation looked in objects class. if send message class sending regular message class object. there implementation looked in called meta-class. meta-classes automatically generated compiler. class methods instance methods of meta-class. handled transparent

i following error message corona sdk : attempt call field "imagesheet" (a nil value) stack traceback. can point out mistake? local ispar = { width = 2541, height = 264, numframes = 7 } local imagesheet = graphics.imagesheet("apus.png, ispar") local apussequencedata = { {name = "fly", frames {1,2,3,4,5,6,7}, time = 800, loopcount = 0} } local apus = display.newsrpite(imagesheet, apussequencedata) apus.x = display.contentwidth/2 apus.y = display.contentheight/2 apus:play() you got function name wrong, supposed graphics.newimagesheet. misplaced quotation marks when calling it. , afterwards misspelt newsprite this code should work: local ispar = { width = 2541, height = 264, numframes = 7 } local imagesheet = graphics.newimagesheet("apus.png", ispar) local apussequencedata = {{name = "fly", frames = {1,2,3,4,5,6,7}, time = 800, loopcount = 0}} local apus = display.newsprite(imagesheet,

i having issue php mailer. sending blank email every time page loaded. i'm sure it's simple (maybe missing condition if submit button hit) fix this. their documentation doesn't seem have 1 though , script first worked when first used started sending emails on page load after first few times. thanks! <form method="post" action=""> <div class="form-group"> <input name="name" type="text" class="form-control" placeholder="enter name"> </div> <div class="form-group"> <input name="email" type="email" class="form-control" placeholder="enter email"> </div> <div class="form-group"> <input name="subject" type="text" class="form-control" placeholder="enter subject"> </div> <div class="form-

i have directory 100 images. need copy of them in various folders along other information download webgl. hence want upload them onto browser , download them again (hope isn't stupid) here code: var imagefile = model.features[cindex].imagename.substring(model.features[cindex].imagename.lastindexof('/')+1); var image = new image(); image.src = model.imagedirectory + imagefile; image.onload = function() { console.info("read \""+image.src + "\"...done"); } image.onerror = function() { var message = "unable open \"" + image.src + "\"."; console.error(message); alert(message); } var data = image.src; zip.file('image_rh_original' + cindex +'.png', data , {base64: true}); is wrong? how similar "todataurl" image object? todataurl method of canvas, , webgl draws canvas. call canvas.todataurl(). need set preservedrawingbuffer true well.

i wondering if possible, , if yes how, can run c preprocessor, cpp, on c++ source file , process conditional directives #if #endif etc. other directives stay intact in output file. i'm doing analysis on c# code , there no c# pre-processor. idea run c preprocessor on c# file , process conditionals. way example, #region directive, stay in file, cpp appears remove #region. you might looking tool coan : coan software engineering tool analysing preprocessor-based configurations of c or c++ source code. principal use simplify body of source code eliminating parts redundant respect specified configuration. it's precisely designed process #if , #ifdef preprocessor lines, , remove code accordingly, has lot of other possible uses.

currently view stuck "watch" outside of other views: ideally have "watch" tabbed in other views such "locals, breakpoints, threads, application output." normally simple dragging "watch" other tabbed views. however, have been unable , snaps solo tab. how combine these tabs? driving me crazy. figured out! wasn't intuitive be: to conjoin separate tabs, need drag tab center of new tab seen in picture below. note. not try drag new tab tabbed part. drag center of want conjoin. in above picture dragging breakpoints tab these tabbed views.
