javascript - How to get random element in Vue.js -


i have 3 hero images , content , want display them randomly when user refreshes page!

basically trying display random div using jquery on loading page, issue size of hero image large , using jquery, these 3 images start loading in dom affects speed of page.

is there solution in vue.js loading 1 specific div @ time, not 3 divs when user refreshes page!?

<div class="slider-item"> <img src="../../../static/img/slides/slide1.png" alt="hello">         <div class="carousel-caption">             <h2>lipsum heading</h2>                 <h4>lipsum dummy content body test dummy goes here.</h4>         </div>     </div>

jquery code:

mounted() {  var random = math.floor(math.random() * $('.slider-item').length);  $('.slider-item').eq(random).show(); },

everything pretty straight forward. randomize link you've chosen in vue.

const app = new vue({    el: '#app',    data: {      images: [        'http://via.placeholder.com/350x150',        'http://via.placeholder.com/200x140',        'http://via.placeholder.com/200x100'      ],      selectedimage: ''    },    created () {      const idx = math.floor(math.random() * this.images.length);      this.selectedimage = this.images[idx]    }  });
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.2/vue.js"></script>  <div id="app">    <img v-bind:src="selectedimage" />  </div>

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 ...
