问题 I am developing mobile web app using ionic sidemenu, but it is not as smooth as it should be. When I open sidemenu using slide left/right, I am getting less than 30 FPS as shown in figure. How can I improve the performance? Reaching 60 FPS would be great! 回答1: AppGyver's Steroids tooling also provides you with access to Crosswalk on Android. You can run it in your Ionic project directly without modifying any files. Also, Supersonic's sidemenu/drawer is fully native, so if you're up for

问题 I'm building an app using the Ionic Framework for which I now want to create some on-off switches (which are basically fancy styled checkboxes). When a person flips the switch I want to send this to the server, so I'm first trying to catch the switch change event. In a basic angular install I tried it with a simple checkbox in the html ( <input type="checkbox" ng-model="theswitch"> ) and a $watch in my controller like so: $scope.$watch('theswitch', function(){ console.log('theswitch changed')

问题 Issue: Error: FileConstructor is not a constructor (evaluating 'new File([blob], "filename.png")') I saw this question Alternative for File() constructor for safari but there weren't any alternatives worth looking at. Is there anyway to work around this using Ionic Framework on IOS? Javascript a = Base64 image. var blob = new Blob([a], {type: 'image/png'}); console.log(blob); $scope.Issue14 = blob; var nfile = new File([blob], "filename.png"); console.log(nfile); $scope.Issue15 = nfile; var

问题 I want to remove the inbuilt grey small caret from ion-select , and use my custom caret(arrow) instead. Code: ion-select { color: grey; background:url("/assets/resources/img/ArrowDownConfig.svg") no-repeat 92% center !important; } But my css code is unable to precedence over the ionic(inbuilt). You can see there are two arrows in the image, one is inbuilt and another is custom. I want to remove inbuilt(ionic) one. 回答1: I don't know how to fix, faced same problem, but it seems to be issue with

问题 I'm working on an app that uses the ionic framework. This in-turn uses the ui-router. Currently, I have a pretty basic two-page app. However, it will expand to be much larger. At this time, I get an error when I transition from my first view to my second view. The error says: TypeError: Cannot read property '1' of null at http://localhost:11000/vendor/ionic/release/js/ionic.bundle.js:14235:28 at updateView (http://localhost:11000/vendor/ionic/release/js/ionic.bundle.js:37839:30) at eventHook

问题 I know there have been a number of posts about this, but none of them are working. My android platform is working perfectly, and shows the app icon and splashscreen, but the ios platform refuses to show them. I tried a number of different folder locations, and I used ionic resources to auto generate the image files and place them in the correct folders and to populate the config.xml, which should work. I don't even know where the app gets the Cordova robot image from, I can't find it anywhere
