javascript - Predictive text search box -


i looking predictive search box performs example provided codpen below.

how edit code instead of predicting word 'california', have array of strings predicts for?

additionally possible make once word complete, script attempts predict next word being typed?

$("#search").keyup(function(){    $("#background-input").val('');    var city = "california";    var searchtext = $("#search").val();    console.log(searchtext.tolowercase());    if(searchtext === "")      $("#background-input").val('');    else if(city.indexof(searchtext.tolowercase())==0)      {        var currentlength = searchtext.length;        $("#background-input").val(searchtext+""+city.substring(currentlength));           }  });
#search-div  {    position: relative;  }  #background-input  {    position: absolute;    color: #999999;    height:25px;    width:250px;  }  #search  {    position: relative;    background: transparent;    height:25px;    width:250px;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div id="search-div">    <input type="text" id="background-input" />    <input type="text" id="search" placeholder="type california.." />  </div>

you have implement loop in existing code after else/if statement loop through each of cities in array, , execute following code on each of strings in array.

this code works me -

$("#search").keyup(function(){   $("#background-input").val('');   var cities = ["california", "london", "paris"];   var searchtext = $("#search").val();   console.log(searchtext.tolowercase());    if(searchtext === "")     $("#background-input").val('');   else {       for(var = 0; < cities.length; i++){         if(cities[i].indexof(searchtext.tolowercase())==0)             {             var currentlength = searchtext.length;             $("#background-input").val(searchtext+""+cities[i].substring(currentlength));              }     }   } });

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
