You can use the map() method along with the ES6 fat arrow function expression to retrieve the values in one line like this: users.map(x => x.mobile); Check the Code Snippet below for a practical example of the ES6 approach above: var users = [{mobile:’88005895##’},{mobile:’78408584##’},{mobile:’88008335##’}]; var mob = users.map(x => x.mobile); console.log(mob); Or if you prefer … Read more
Actually all you need is .nonactivatingPanel style panel. Everything else is details, like level of this window, custom views with overridden acceptsFirstMouse:, needsPanelToBecomeKey, etc. Btw, button accepts first click by default, non activating app in this case. So your AppDelegate, for example, might look like the following: class AppDelegate: NSObject, NSApplicationDelegate { var docky: NSPanel! … Read more
GOTO statements are useful ? Yes. But not for this use case. how I can go to initial stage of program again when user press Y There’s a control flow structure for going back and repeating. It is called a loop. An example: do { // do some stuff cin>>q; } while(q==’Y’); 2 solved How … Read more
I suggest you edit your question to represent accurately what you are looking for. Based on your comments, if you are looking for the FIRST DIV, use something like this:- x=document.getElementsByTagName(“div”); if (x!= ‘undefined’ && x.length > 0 ) document.write(x[0].id); 2 solved find id of element [closed]
The problem is with this: char *name = new char; You’re only allocating 1 char, and that is not enough if you want to store into it something larger than 1 character (not to mention that you need another one for the null-terminator). Instead try something like this: char* name = new char[64]; // Be … Read more
In C++ (and many other languages), operator && is a logical AND operator, which yelds true only when both conditions are true. If any of the conditions is false, the whole statement is false. The code executes once because the do while loop actually tests the condition at the end, after executing. If you would … Read more
public class Test { public static void main(String[] args) { String input = “eye-of-tiger”; String modified = dashToUpperCase(input); System.out.println(modified); } private static String dashToUpperCase(String input) { StringBuilder result = new StringBuilder(); boolean toUpper = false; for (int i = 0; i < input.length(); i++) { char c = input.charAt(i); if (c == ‘-‘) { toUpper … Read more
This kind of prompt is for the users’ own protection, and the Android API does not allow developers to disable it. So in short: There is no way to do this legitimately. solved How can set system preference programmatically let prompt message don’t display?
There are a couple of simple basic ideas you can put to work here. First, take the input audio and divide into small sized buckets (on the order of 10’s on milliseconds). For each bucket compute the power of the samples in it by summing the squares of each sample value. For example say you … Read more
The pictured code (please include actual code in the future, not screenshots of code) returns fact immediately: for ( n = 1; n <= num; n++ ) { return fact * n; } since n starts at 1. What you want is to include fact in the function, and multiply it as the loop goes … Read more
The in operator makes it possible to see whether an object has a property with a particular name. if (“name” in object) { … } Without in, that would be harder. You can test for null or undefined, but that doesn’t answer the question unambiguously. Note that the token in also appears in the for … Read more
As a partial solution for the functions / methods (if they don’t need arguments) you can use Threads or an ExecutorService and method references. If you need arguments you will have to write lambda expressions – see the method t3 and it’s start for an example. public class Test { public void t1() { System.out.println(“t1”); … Read more
If you’re using jQuery then use this: $(‘#sensor’).change(function() { $(‘#sensorText’).val( $(this).find(‘option:selected’).data(‘foo’) ) }) $(‘#sensor’).change(function() { $(‘#sensorText’).val( $(this).find(‘option:selected’).data(‘foo’) ) }) <script src=”https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js”></script> <form id=”example” name=”example”> <select id=”sensor”> <option value=”Jval” data-foo=”Jfoo”>Joption</option> <option value=”Kval” data-foo=”Kfoo”>Koption</option> </select> <br /> <input type=”text” value=”” id=”sensorText” /> </form> 1 solved Populate an input with the contents of a custom option (data-) attribute
I just solved the issue.The problem was that mosquitto was not capable of reading the files not because of permission issues but because of the filepaths. So the thing was that when defining the filepaths in the mosquitto.conf I had to use: cafile /etc/mosquitto/ca_certificates/ca.crt certfile /etc/mosquitto/certs/server.crt keyfile /etc/mosquitto/certs/server.key Instead of: cafile c:\etc\mosquitto\ca_certificates\ca.crt certfile c:\etc\mosquitto\certs\server.crt keyfile … Read more
There’s a wealth of information out there, http://ruby-doc.org/core-2.3.0/Hash.html for example is pretty clear on what hashes are. You need to get your head around some of the basics, there are plenty of tutorials out there, https://www.railstutorial.org/ is one that comes up often, http://guides.rubyonrails.org/getting_started.html is the most obvious place to start. 2 solved hashes — Seem … Read more
