jquery - Making Javascript button toggle function work with dropdown selection -


i complete newbie in of world javascript, html , css. have html page several charts created using highcharts. page has dropdown menu containing list of indian states. when state selected, charts updated data state. each chart has set of 2 buttons attached (see fiddle link). on toggling buttons, different charts loaded.

now issue: need make both these functionalities work together. is, when select "andhra pradesh", data andhra pradesh should loaded on both charts. able make charts load respective data states "2017-18" couldn't "other years". can't fathom going wrong. here's link fiddle: https://jsfiddle.net/pr4chi/w9nq1cw3/110/

and here's code toggle chart: 

$(document).on('click', '.chart-update', function() {     $('button').removeclass('selected');         $(this).addclass('selected');         chart.destroy();     $('#donut').highcharts(chartoptions[$(this).data('chartname')]);     chart = $('#donut').highcharts();   });

any appreciated!

you can bind change event select element , based on state chosen, update chart series' data. take @ example below. added dummy data (check dataforstates object) show how works.

api reference:
http://api.highcharts.com/highcharts/series.update
http://api.highcharts.com/highcharts/series.setdata
https://api.jquery.com/change/

example:

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
