Answer : There is no way to do it without looping through every element. You could, of course, write a function to do it for you. function addEventListenerList(list, event, fn) { for (var i = 0, len = list.length; i < len; i++) { list[i].addEventListener(event, fn, false); } } var ar_coins = document.getElementsByClassName('coins'); addEventListenerList(ar_coins, 'dragstart', handleDragStart); or a more specialized version: function addEventListenerByClass(className, event, fn) { var list = document.getElementsByClassName(className); for (var i = 0, len = list.length; i < len; i++) { list[i].addEventListener(event, fn, false); } } addEventListenerByClass('coins', 'dragstart', handleDragStart); And, though you didn't ask about jQuery, this is the kind of stuff that jQuery is particularly good at: $('.coins').on('dragstart', handleDragStart); The best I could come up with was ...

Answer : You need to install create-react-app npm module, before you use this feature. npm install -g create-react-app You can read more about this feature on the official release blog of WebStorm. Excerpt from the documentation : Make sure that you have create-react-app installed globally on your computer, for that run npm install -g create-react-app. Then to start your new project, double click on the start task in the npm tasks tool window to run it. That’s it! I had ie installed create-react-app globally using yarn and webstorm failed to find it. Then I used npm , not to mention globally and its working like a charm.

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Example: what is time complexity of insertion sort Time Complexity is : If the inversion count is O ( n ) , then the time complexity of insertion sort is O ( n ) . Some Facts about insertion sort : 1. Simple implementation : Jon Bentley shows a three - line C version , and a five - line optimized version [ 1 ] 2. Efficient for ( quite ) small data sets , much like other quadratic sorting algorithms 3. More efficient in practice than most other simple quadratic ( i . e . , O ( n2 ) ) algorithms such as selection sort or bubble sort 4. Adaptive , i . e . , efficient for data sets that are already substantially sorted : the time complexity is O ( kn ) when each element in the input is no more than k places away from its sorted position 5. Stable ; i . e . , does not change the relative order of elements with equal keys 6. In - place ; i . e . , only requires a constant amount O ( 1 ) of additional memory space Online ; i . e . , can sort a list a...

Answer : For Vuetify 2.0 you can try following method. (After following Vuetify 2.0 Upgrade guide for themes) import Vuetify from './plugins/vuetify' export default { getters: {}, mutations: { toggleDarkTheme(state) { Vuetify.framework.theme.themes.light.primary = "#424242"; } } $vuetify is an instance property hence you can access any vue instance property using Vue.prototype.$prop For your case import Vue from 'vue'; export default { getters: {}, mutations: { toggleDarkTheme(state) { Vue.prototype.$vuetify.theme.primary = "#424242"; } } }; For Nuxt.js projects with Vuetify set as a buildModule , you can access $vuetify from the $nuxt property in the Vue instance: import Vue from 'vue'; export actions = { yourAction() { Vue.prototype.$nuxt.$vuetify.theme.dark = true; } }

Answer : I was facing the same issue. For me, it got resolved by setting proxy settings. Android Studio > File > Settings >appearance and behavior> System Settings > HTTP Proxy I would suggest checking any proxy is required to enable internet for your android studio. Hope this will help somebody. Open Android SDK Manager Click on Tools. Click on Android. Click on SDK Manager. Update your SDK's Then Sync ,Re-Build and Restart Your Project "Launch Standalone SDK Manager" is not available in newer versions. Just select "SDK Tools" tab, then "Android SDK Build-Tools and place a check next to 23.0.1, 23.0.2, 23.0.3, etc. and any others you may want to install. Select Apply and when complete, press Finish. Rebuild and see if that helps.

Answer : You can add a check to only clear when the text in the field is not empty (i.e when the length is different than 0). field1.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable s) {} @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { if(s.length() != 0) field2.setText(""); } }); field2.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable s) {} @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { if(s.length() != 0) field1.setText(""); } }); Documentation for TextWatcher here.

Answer : Google's tools do not provide any way to do this kind of thing built in. While you might be able to do this by routing to a sufficient number of locations and checking the time, another tool that you might be interested in is Graphserver. GraphServer is a multimodal trip planner, which can take data from OpenStreetMap and other data sources. Some of the gallery images show growing shortest-path distance routing, and this is based on a similar metric. The Google Group would be the appropriate place to discuss the possibilities of using this tool. Note that this is not a pre-baked tool; it will likely require some investigation and work to get it to solve your problem, but the tool can be used to do it. Take a look at the Mapnificent API. Mapnificent provides dynamic public transport travel time maps for many cities in the US and some world wide. You can use the Mapnificent API to augment your Google Maps application with public transport travel time ...

Answer : I think that, in fact, this is possible. You have to define a custom slot type, as explained here: https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/defining-the-voice-interface#custom-slot-types Now, the custom slot type asks you to provide possible values, which you should do. BUT! It seems that Alexa will still parse slot values correctly even if they are not in the list of possible values that you provided! This seems to be an undocumented feature and what I am telling you is based on my own observations: My custom slot type is taking on unexpected values In general, my impression is that the interaction model as a whole should be seen less as a strict set of rules and more as a guideline that is interpreted at the discretion of the Alexa Voice Service. I was able to achieve this exact thing by creating a custom intent called "Search" with a custom slot type called 'query.' This sends whatever the user says in the slot v...

Answer : You can remove a query parameter by using the merge option of queryParamsHandling and passing in null for any params you wish to remove. // Remove query params this.router.navigate([], { queryParams: { 'yourParamName': null, 'youCanRemoveMultiple': null, }, queryParamsHandling: 'merge' }) This option is simpler and requires less work to ensure you are not removing other params. You also do not need to worry about cleaning up an observable subscription when your component is destroyed. UPDATE: @epelc's answer below is the up-to-date and correct way to do this: https://stackoverflow.com/a/52193044/5932590. Unfortunately, there is no clear-cut way to do this currently: https://github.com/angular/angular/issues/18011. However, as jasonaden commented on the linked thread, This could be done manually by merging the old and new query params, removing the key you don't want. Here is one way to do that: Let's say...
