html - IONIC 2 radio button inside Virtual scrolling ,multiple option getting selected automatically if I select any one of the option -


here code virtual scrolling

 <ion-list [virtualscroll]="options" *ngif="options.length>99" radio-group style="opacity: 0.9;">     <ion-item *virtualitem="let option">         <ion-label style="font-size: 12pt" text-wrap>{{ option.optiontext }} </ion-label>         <ion-radio value='{{ option.optionid }}' (ionselect)="setselectedoption(option)"></ion-radio>     </ion-item>        </ion-list>

any appreciated thanks

edit-i found out issue has been raised on github still if me workaround helpful

ok you're looking workaround.

if @ docs <ion-radio>, there option called checked, normal radio button. mean this:

<ion-radio value='{{ option.optionid }}' (ionselect)="setselectedoption(option)" [checked]="ischecked(option.optionid)"></ion-radio>

ts

options: = []; selectedoptions: number[] = [];  constructor() {}  setselectedoption(option: any) {     let index = this.selectedoptions.indexof(option.optionid);     if(index > -1) {        this.selectedoptions.push(option.optionid);     } else {        this.selectedoptions.slice(index, 1);     } }  ischecked(id: number): boolean {     // true if id in selectedoptions, false if isn't     return (this.selectedoptions.indexof(id) > -1); }

edit

try normal html radio inputs since ionic ones seem bugged then

<form action="">    <ion-list [virtualscroll]="options" *ngif="options.length>99" style="opacity: 0.9;">       <ion-item *virtualitem="let option">         <ion-label style="font-size: 12pt" text-wrap>{{ option.optiontext }} </ion-label>         <input type="radio" [value]="option.optionid" (click)="setselectedoption(option) [checked]="ischecked(option.optionid)">     </ion-item>          </ion-list> </form>

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 ...
