javascript - Ojbc invoke js error: Can't find variable require -


i'm totally new js. i'm developing on ios , need use web3js in our program. it's ok call js function in obj-c. however, use 'require' import web3js modules, throws 'referenceerror: can't find variable: require'. happens? did miss anything? can help?? many thanks.

update:

if 'require' not usable, how use other modules js invoked obj-c?

here code.

obj-c code:

nsstring* path = [[nsbundle mainbundle] pathforresource:@"bridge/src/index" oftype:@"js"]; jsfunc = [nsstring stringwithcontentsoffile:path encoding:nsutf8stringencoding error:nil];  jscontext* jscontext = [[jscontext alloc] init]; [jscontext evaluatescript:jsfunc]; jsvalue* func = jscontext[@"getaddress"]; jsvalue* = [func2 callwitharguments:@[@"0x8730f6ad1c0d387644590966bdbfedba44fe250118df0f97f11190ad5727b312"]];

js:

function getaddress(prvkey) {   try{       var web3 = require('../../3rd_party/web3.js-1.0.0');            var web3 = new web3();       return web3.eth.accounts.privatekeytoaccount(prvkey);   }   catch (e)   {       return e;   } }

i used browserify package modules , used webview call js functions.

here js file, index.js

"use strict" let web3 = require('web3.js'); window.web3 = web3;

and use broswerify pack 

browserify index.js -o web3.js

my html, 

<html> <head>     <script type="text/javascript" src="web3.js"></script>    </head> <body>     <script type="text/javascript">         function getaddress(prvkey)         {             try             {                 var web3 = new web3();                 var account  = web3.eth.accounts.privatekeytoaccount(prvkey);                 return account.address;             }             catch (e)             {                 return e;             }         }     </script> </body>

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer
