javascript - Quick Way to "Un-Angularize" a JS Object -


angular adds expando properties, "hashes," etc., deep object structure when two-way binding in use. that's fine, i'm interested in retrieving json snapshot of object tree things belonged there. angular provide way "vanilla" version of bound object?

(i wouldn't want merely store "original value" before binding kicks in, since want reflect changes made via ui.)

short answer:

there's nice built in function:

angular.tojson(yourobj);

longer explanation:

the difference between angular.tojson , json.stringify runs through filter strips out hashes/ids , turns window, document, , scope strings. if want roll own function this: here relevant snippet angular.js source code:

if(/^\$+/.test(key)) {     val = undefined; } else if (iswindow(value)) {     val = '$window'; } else if (value &&  document === value) {     val = '$document'; } else if (isscope(value)) {     val = '$scope'; }

note: iswindow , isscope functions not exported, you'd need little more hacking function work same way.

source: http://docs.angularjs.org/api/angular.tojson , https://github.com/angular/angular.js/blob/master/src/angular.js

there's angular.fromjson function json.parse.

update it's worth noting $http service automatically when specify model data $http request.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
