问题 <script type="text/javascript"> var geo = new GClientGeocoder(); function showAddress() { var search = document.getElementById("search").value; // getLocations has not ret, so wtf! geo.getLocations(search, function (result) { (result.Status.code == 200) ? alert(result.Placemark[0].Point.coordinates) : alert(result.Status.code); }); }</script> I need the ret value of the callback as getLocations() returns no values.

Modifying an outer variable within an anonymous inner class

由 家住魔仙堡 提交于 2019-12-11 21:50:48
问题 As I understand it, any variables used within an inner anonymous class (but declared outside of it) are actually passed a copy of their values. There is also a requirement that these outer variables be declared as final, which obviously means that these variables are not meant to be modified. But is there any kind of work-around to this? Can my anonymous inner class actually modify some variable or object, which I could then use later on in my code (outside of the anonymous class)? Or would

Why can't Javascript ES6 call an anonymous super function? [duplicate]

问题 This question already has an answer here : Accessing a class field on a superclass (1 answer) Closed 4 months ago . Please explain the difference between using a parent-child relationship using anonymous functions and using class functions? In case 1 everything works as expected. In case 2, codepen does not return any results. //CASE 1 class Parent { constructor(name) { this.name = name; } exec() { console.log('name', this.name); } } class Child extends Parent { constructor(name, age) { super

Set global variable within anonymous function

问题 I want to query a value from a script and use the value as variable for further functions. This code returns zero despite a value is set. var total = 0; var jqxhr = $.getJSON("number.php?jsonp=?", function(data) { total = data[0]['Total']; // e.g 1234567 }); alert (total); // gives zero I read that the problem could be with the asynchronous call and that my alert is executed before the anonymous function. I also tried to use some kind of setter function but withous success. How can I set the

Is there a short Lambda expression for a->a->Ordering?

由 人走茶凉 提交于 2019-12-11 12:12:48
问题 Lambda Expressions can make life easier and I love the way, you can shorten expressions like (\x -> x + 1) to (+1) . That's why I'm wondering if there is anything similar for anonymous functions that take two arguments and return a Ordering . For example: Can you shorten this code: sortByFirst :: Ord a => [(a, b)] -> [(a, b)] sortByFirst = sortBy (\x y -> fst x `compare` fst y) 回答1: You could use the on function, from the Data.Function module. import Data.List sortByFirst = sortBy (compare

C# Anonymous Function Scope in Unity3D

问题 I came across this puzzling behavior while making a simulation project in Unity3D. Basically, I was creating anonymous functions in a loop using the variable being looped, and add all these functions to a queue for processing. The curious case in Unity3D Monobehavior is that they are only called on the last looped variable. using UnityEngine; using System.Collections; using System.Collections.Generic; using System; public class TestDist : MonoBehaviour { int counter = 0; // Use this for
