javascript - Return Input from Custom Popup -


i working on custom modal popup entity. when need text value user, make html element visible, need value enter in text field when press "enter" button.

the problem i'm trying doesn't seem have easy implementation. don't think it's possible without promises, , attempts far have not worked. ideas on possible solutions?

turns out managed myself. had assumed promise somehow end when reached end of code, not true: continue when resolve manually. therefore when set onclick of button possibility of resolving it, wait button pressed. see code sample below:

var modalpopup() = function() {   //display popup   document.getelementbyid("generalmodalbackground").style.display = "flex";    return new promise(function(resolve, reject) {     document.getelementbyid("generalsubmitbutton").onclick = function() {       //when clicked, resolve promise inputted value       let returnval = document.getelementbyid("generaltextfield").value;       resolve(returnval);     }   }); }  modalpopup().then(function(textneeded) {   //do stuff need });

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 ...
