jquery - changing coloum data in kendo grid conditionaly -


i trying change value of colums in kendo grid conditionaly. grid id binded data needs modifications in data binded.

i have used couple of sample codes got stackoverflow none of them reflecting. there no change in grid data

1st way 

var grid = $("#grid").data("kendogrid");              var items = grid.datasource.data();             (var = 0; < items.length; i++) {                 items[i]["matchcount"] = "4";             }

2nd way tried

var dataitem = $("#grid").data("kendogrid").datasource.data()[0];         dataitem.set("matchcount", "ccc");

3rd way 

  var dataitem = $("#grid").data("kendogrid").datasource.data()[0];      dataitem.set("matchcount", "50");

the way grid binded below:

  $("#grid").kendogrid({         datasource: datasource,          columns:         [             { field: "rowid", title: "rowid", hidden: true },             {                 field: "lastname",                 title: "last name",                 width: 150,                 editable: false,                 headertemplate: createheadertemplate("last name")              },            {                 field: "matchcount",                 width: 120,                 editable: false,                 template: "#if(matchcount == 0){#<span>#=matchcount#</span>#}else{#<a href='javascript:void(0)' onclick='showmatches(&quot;#=lastname#&quot;,&quot;#=firstname#&quot;,${matchcount},&quot;#=matchids#&quot;);' style='margin-left:50px' >#=matchcount#</a>#}#"             }          ],         edit: function (e) {             //e.container.find("input[name='name']").each(function () { $(this).attr("disabled", "disabled") });                },         editable: false     });

you're doing ok in attempts 2 , 3. perhaps need run refresh() method:

dataitem.set("matchcount", "50"); grid.refresh();

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

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
