node.js - How can I use data passed into jade template in the views javascript? -


rendering data template res.render('account/pets/allpets', { petmap, title: 'all pets' }) have tried 2 thing make work

a)

        var neighborhoods = [];         (var = 0; < petmap.length; i++) {          neighborhoods.push(new google.maps.latlng(petmap[i].location.loc[0],pet.location.loc[1]))         }

b)

    var neighborhoods = [     each pet in petmap       new google.maps.latlng(petmap[i].location.loc[0],pet.location.loc[1])     ]

assuming patmap javascript object, required few hacky things make work. pug renders serverside, while javascript on client, cannot directly access pug variable in js. can convert js object string when pug compiles, parse json when client executes.

var petmap = json.parse(("#{json.stringify(petmap)}").replace(/&quot;/g, '"')); /*     let me break down in terms of execution     "#{json.stringify(petmap)}" -> executes server side, converts #{} accesses pug variable petmap, has been converted object     .replace(/&quot;/g, '"') -> replaces quote escape sequences (something html security) quotes json can parsed     json.parse -> parses json stringified json server sent client */

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
