Javascript, extending ES6 class setter will inherit getter
In Javascript, use the following illustration code: class Base { constructor() { this._val = 1 } get val () { return this._val }}class Xtnd extends Base { set val(v) { this._val = v }}let x = new Xtnd(); x.val = 5;console.log(x.val); // prints ‘undefined’ Instance x does not inherit get val() from the Base class ….Javascript actually treats a missing getter as undefined when a setter is present. I have a situation where I have a number of classes that all have the exact same set of getters but a unique setter. Currently, I Just copy the getters in each class, but I’m refactoring and want to eliminate redundant code. Is there a way to tell JS to keep the base class’s getters, or does anyone have an elegant solution to this problem? plan? Workaround: This limitation is due to how Javascript handles property accessors behind the scenes. In ECMAScript 5, you end up with a prototype chain that contains a property descriptor for val, which contains the get method defined by your class, and an undefined set method. In your Xtnd class you have another val property descriptor which hides the entire Property descriptor, containing the set method defined…
Convert image object to File object, javascript
I want to convert an “Image Object” to a “File Object” using HTML5 on the client side to upload files to azure blob storage. Since I’m using AngularJs, my plan is Convert images to files Use angular-azure-blob-upload to upload files to blob storage I found many examples of using FileReader to convert a File object to an image, but I couldn’t find an example of the opposite. I heard that writing a file to the local file system using client-side Javascript is not possible, but I don’t need to store the file, I just need a file object reference to upload the file. Is there any way to solve this problem?

The beauty of javascript, “javascript”
What is the use of the dollar sign in Javascript? ? ? It has no special function, but everyone is accustomed to defining commonly used functions and face changes starting with $. For example, if I want to get an element, I often write document.getElementById(“e_id”) like this. Many people are used to defining it as: function $id(id){return document.getElementById(id);} , just write $id(“e_id”) when using it, which is simpler and more convenient to write. Dollar sign in Javascript right context returns the characters between the last matching position of the searched string and the end of the string . Read only Excerpted from Javascript Language Reference What is Javascript? Javascript (js for short) is a client-side scripting language that is object- and event-driven and relatively secure. It is also a scripting language widely used in client-side web development. It is often used to add dynamic functions to HTML web pages, such as responding to various user operations. Originally designed by Brendan Eich at Netscape, it is a dynamic, weakly typed, prototype-based language with built-in support classes. Because Netscape cooperated with Sun, Netscape management wanted it to look like Java, so it was named Javascript. In web pages, there are two main…

Addfunctionstoexecute{apple,java}script
It would be great to have hydra.runapplescript() and hydra.runJavascript() that accept a string as a parameter, go off and execute that code, and return any output, e.g.: 1234567 lua foo = hydra.runapplescript [[ tell application “Safari” set currentURL to URL of document 1 end tell return currentURL ]] would set “foo” to the value returned from currentURL. This question comes from the open source project: mjolnirapp/mjolnir Great, thanks.
