css - Apply text to hover based on condition in AngularJS -


how can select specific text appear in hover based on logic using angularjs? example, have value , if class equals 'warning' want specific hover message, if class equals 'success' want different hover message appear.

my logic write function says if color = success hover = this, if color = warning hover = that, if color = error hover = else. advice?

      getcolor = function() {              var data = 88;                if(data < 75){                  return "losses-success";              }else              if(data >=75 && data < 90){                  return "losses-warning";              }else              if(data > 90){                  return "losses-error";              }          };
.losses-success{      display: inline-block!important;      width: 8px;      height: 20px;      background-color: green;  }  .losses-warning{      display: inline-block!important;      width: 8px;      height: 20px;      background-color: yellow;  }  .losses-error{      display: inline-block!important;      width: 8px;      height: 20px;      background-color: red;  }
<div id="ctotal" class="losses-tooltip" ng-class="getcolor()">    <span class="tooltiptext"> </span>    <span class="block"><sup>$</sup>      <strong class="amount">{{loss}}</strong></span>  </div>

if classes , messages fixed, think it's better return object class , message:

return {      ngclass: "losses-success",      message: "some text" }

than can use class property in ng-class , show message related property.

<div id="ctotal" class="losses-tooltip" ng-class="getcolor().ngclass">      {{getcolor().message}} </div>

i don't approach much, because getcolor() function called on every angular cycle. , getcolor().ngclass syntax seems weird me.

i prefer set object in controller, , update values when it's needed. if can't control when class , message updated, can choose first approach. if able control this, can simply:

function getcolor(value) {     //put logic     //     $scope.myobj = {          ngclass: "anyclass",          message: "any message"     } }

and in template:

<div id="ctotal" class="losses-tooltip" ng-class="myobj.ngclass">      {{myobj.message}} </div>

note in second approach need call getcolor function update values in myobj, have better performance.

in first approach function called on every cycle, values updated every time (you don't need call function explicitly in controller update value). so, in case need careful performance of application.

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
