javascript - ajax call returns values and my html page -


i performing ajax call controller following code:

$.ajax({     type: "post",     url: "@url.action("uploadimage", "item")",     data: '{ "imagedata" : "' + image + '" }',     contenttype: "application/json; charset=utf-8",     datatype: "json",     success: function (success) {         alert('success ' + success.responsetext);     },     error: function (response) {         alert(response.responsetext);     } });

this controller : 

[httppost] public actionresult uploadimage(string imagedata) {     string imagename = guid.newguid().tostring();      try     {         productmanager pm = new productmanager();         pm.addnewproduct(imagename);     }catch(exception e)     {         writetolog(e);     }     return json(new { success = imagename }, jsonrequestbehavior.allowget); }

it gets controller , addnewproduct function runs successfully. problem want return image name created within controller. works return complete html page. alert on success , when error occurs somehow ends in error following alert :

enter image description here

it shows value need why return complete html well?

  • you not need jsonrequestbehavior.allowget. must used get requests in order protect against specific attack involving json requests. , in code using post verb.

  • you should use follow code in order success string received server.

    success: function (response) { alert('success ' + response.success); }

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 ...
