object

问题 The problem is that I am saving projects, which are made with project factory function. The projects also have addToDo method and I am saving this projects into myProjects array. I am struggling with, that when my projects are saved or retrieved to/from localStorage, they loose functionality (addToDo method). As after page refresh I can't add todos to the projects anymore. So I guess that method of project factory isn't saved to localStorage. Thanks. let newProject; let myProjects =

问题 I was happily using Map for indexed accessed everywhere in my JavaScript codebase, but I've just stumbled upon this benchmark: https://stackoverflow.com/a/54385459/365104 I've re-created it here as well: https://jsben.ch/HOU3g What benchmark is doing is basically filling a map with 1M elements, then iterating over them. I'd expect the results for Map and Object to be on par, but they differ drastically - in favor of Object. Is this expected behavior? Can it be explained? Is it because of the

问题 I have a problem with loading data into an < object > using Javascript. It refuses to work in Chrome, no error message either. You can see a minimal example to play with here: http://tinkerbin.com/HIqG0ypb 回答1: It is strange to me that browsers assume object.data could be set as URI but display content available at that URI . It sounds like a security flaw : full content could be injected into a page without using frame. I wonder if test.com in your example has access to window.parent or

问题 I have two arrays of objects in Java, which contain some fields that I need to compare, but the thing is I need to compare element by element, that means, that I want the compare a field from the first object in my first array with the first object in my second array, my second object from the first array with my second object from the second array and so on. This is what I have done so far, but the idea is that I do not know what should be the limit for my second array. From my point of view

问题 I'm looking for an object to object mapper for Android. It's all about an automation of Java Bean to Java Bean copy so that each field with a name xyz will match a field xyz in another class. I've tried already each of those in Java http://www.javacodegeeks.com/2013/10/java-object-to-object-mapper.html But none is Android compilable, do you have any ideas what to try? 回答1: I have been using this , a mapper for pojos https://github.com/txusballesteros/android-transformer 回答2: I used http:/

问题 I'm trying to remove keys from an object where the values is Array(0). Here's the object: {fruit: Array(1), dairy: Array(2), vegetables: Array(0)} This is the desired result: {fruit: Array(1), dairy: Array(2)} So far, I've been playing with the delete operator and .filter/.reduce methods. Any help would be awesome :) 回答1: Just iterate over the keys of the object, check if the value for that key is an empty array and if so, delete it: let obj = { a: [1], b: [], c: 5, d: false } for (const key
