watch

问题 I have a Vue instance with two watchers: watch: { zone:function(zone) { console.log('Zone watcher'); this.route = {}; }, route:function(route) { console.log('Route watcher'); if(Object.getOwnPropertyNames(route).length === 0) { var _this = this; axios.get(route.url).then(function(response) { _this.tracks = response.data; }); } else this.tracks = {}; } }, When a user selects a zone, route (and tracks) are reset. When user selects a route, tracks are loaded; I have a component receiving zone

问题 I'm hoping to use Webpack compile all our less files in /less to /public/css and include them in our server-side templates as regular css ( not sticking the text into the using ExtractText plugin or overloading require). That is, I'm trying to get Webpack + a LESS loader or plugin to glob to compile all the .less files: /less/foo.less /less/bar.less /less/unknown-new-less-file.less ... and output them to /public/css/foo.less /public/css/bar.less /less/unkown-new-less-file.less I then want to

问题 I'd like to see the member variables of objects whilst debugging in Qt Creator. I can see all of the internals of my own objects, but I can't see the members of a QGraphicsView , for example. I'm also curious to know why it says <unavailable synchronous data> for std::map . Here's a small example of that: #include <map> #include <string> int main(int argc, char *argv[]) { std::map<int, std::string> someMap; someMap.insert(std::make_pair(1, "cats")); someMap.insert(std::make_pair(2, "dogs"));

问题 I have this service which checks if there a new data from the back end. It it working fine.But the problem is I cant get the data from the service to the controller using $watch nor using the promise . SERVICE .service('notificationPollService',function($q, $http, $timeout){ var notification={}; notification.poller = function(){ return $http.get('some/routes/') .then(function(response) { $timeout(notification.poller, 1000); if (typeof response.data === 'object') { return response.data; } else

问题 Does PHP have the ability to watch a variable (or object property) and run a function when its value changes, similar to Gecko's Javascript watch function? 回答1: XDebug might have this, but I don't know for sure. If you're trying to debug a member variable on an object, you can use overloading: public function __set($var, $val) { if ($var == 'interesting') { echo "$var set to: "; var_dump($val); } $this->$var = $val; } 回答2: This would be possible when using XDebug along side an IDE like

问题 I'm having an error with GruntJS when I try to run a grunt watch . It works fine, until there is a change in the file it is watching, then, it looks something like this: Running "watch" task Waiting...[1] 2464 bus error grunt watch The number 2464 changes. It seems to be the port that grunt is watching on? But, I'm not sure. Here is my Gruntfile: module.exports = function (grunt) { "use strict"; grunt.initConfig({ pkg: grunt.file.readJSON('package.json'), sass: { dist: { options: { style:

问题 Thanks in advance for helping me. I want to create a product build on changes inside src directory. For that I used watch package of npm. Below is my "scripts" inside package.json "scripts": { "webpack-dev-server": "webpack-dev-server", "dev": "watch 'npm run prod' src", "prod": "webpack --mode=production" }, Now when I run npm run dev command. It gives me: Error: ENOENT: no such file or directory, stat 'E:\projects\chatapp\run' 回答1: Try with npm install maybe it solves or you can look at

问题 I'm working with Python and Jython to deploy applications to WebSphere. However, we are running into an issue with the WAS libraries where calls to these actions will sometimes take up to 30 minutes to execute. In order to troubleshoot this issue, I need to be able to keep tabs on if a process is still executing after so many minutes and, if so, send an alert. I'm assuming I will need to put the call in a separate thread and watch it, but I have no experience with multithreading. What is the

问题 Here's something I know is probably possible but I've never managed to do In VS2005(C++), While debugging, to be able to invoke a function from the code which I'm debugging. This feature is sometimes essential when debugging complex data structures which can't be explored easily using just the normal capabilities of the watch window. The watch window seem to allow writing function calls but every time I try it it gives me one error or another. Error: symbol "func" not found Error: argument

问题 i wrote a small script on python that calls a command line from the console in order to hibernate a linux machine (or shut itself down in case one word is changed) and then wake up after some time. The command is called again again and again through the watch command. import os import time os.system("watch -n 20 sudo rtcwake -u -s 10 -m mem") So the rtcwake command is called again 20 seconds after the pc has wokn up again. I would like another script to be run every time the computer wakes up
