so i'm trying scrape json exists in website source , use in own site. heres example site: view-source: http://www.viagogo.co.uk/theatre-tickets/musicals/the-lion-king/the-lion-king-london-tickets/e-1545516 if partway down there var eventlistings i code exists in var so far have this: url = "http://www.viagogo.co.uk/theatre-tickets/musicals/the-lion-king/the-lion-king-london-tickets/e-1545516" doc = open(url).read any ideas how can this? thanks the code have far (basically) function using open-uri ruby standard library . standard library module, require 'open-uri' @ top of file in use it. open::uri treats job give contents of file. if comfortable using tools search raw text particular contents looking for, may enough. there few gems, though, assume html , provide special support finding html elements , inspecting contents. this post uses mechanize in turn built on top of nokogiri . easier write working code when using library

i'm trying create async method in project takes input parameters. if parameters correct stuff , call completion block. however, if input parameters not correct won't stuff (and completion block won't run , i'd have call myself). anyway, i'm wondering best approach this... i'm thinking have method return status enum includes wrong input , have completion block. the problem there error completion block. maybe should different error type? something this... (using login example). enum loginrequeststatus { case missingemail case missingpassword case requestinglogin } and error completion might be... enum loginerror: error { case nouserfound case invalidpassword case success } then function might this... func login(withemail email: string, password: string, completion: (loginerror?) -> ()) -> loginstatus { if email.isempty() { return loginstatus.missingemail } if password.isempty() { re

this question has answer here: explanation of jsonb introduced postgresql 6 answers what's difference between json , jsonb data type in posgressql? when should used specific one? what's benefits or disadvantages respect other? this explain: https://www.citusdata.com/blog/2016/07/14/choosing-nosql-hstore-json-jsonb/ in cases jsonb want when looking nosql, schema-less, datatype. hstore , json can have place it’s less common. more broadly, jsonb isn’t fit in every data model. can normalize there benefits, if have schema has large number of optional columns (such event data) or schema differs based on tenant id jsonb can great fit. in general want: jsonb - in cases json - if you’re processing logs, don’t need query, , use more of audit trail hstore - can work fine text based key-value looks, in general jsonb can still work great h

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

i have function foo makes ajax request. how can return response foo ? i tried return value success callback assigning response local variable inside function , return one, none of ways return response. function foo() { var result; $.ajax({ url: '...', success: function(response) { result = response; // return response; // <- tried 1 } }); return result; } var result = foo(); // ends being `undefined`. -> more general explanation of async behavior different examples, please see why variable unaltered after modify inside of function? - asynchronous code reference -> if understand problem, skip possible solutions below. the problem the a in ajax stands asynchronous . means sending request (or rather receiving response) taken out of normal execution flow. in example, $.ajax returns , next statement, return result; , executed before function passed success callback

i'm new web apps , servlets , have following question: whenever print inside servlet , call webbrowser, returns new page containing text. there way print text in current page using ajax? indeed, keyword "ajax": asynchronous javascript , xml . however, last years it's more asynchronous javascript , json . basically, let js execute asynchronous http request , update html dom tree based on response data. since it's pretty tedious work make work across browsers (especially internet explorer versus others), there plenty of javascript libraries out simplifies in single functions , covers many possible browser-specific bugs/quirks under hoods, such jquery , prototype , mootools . since jquery popular these days, i'll use in below examples. kickoff example returning string plain text create /some.jsp below (note: code doesn't expect jsp file being placed in subfolder, if so, alter servlet url accordingly): <!doctype html> <html l
