javascript - Is it possible for a Java controller to pass an attribute to a success ajax call? -


as title says, want pass variable controller success ajax call function possible? example:

i have java class controller this:

@requestmapping(value = "checkfruit", method = requestmethod.post) @responsebody public modelandview checkfruit(httpservletrequest request, string fruitinput) {      modelandview modelandview = new modelandview();       if (fruitinput.equals("apple")) {         modelandview.addobject("fruittype", 1); //this want pass success ajax call.     } else if (fruitinput.equals("orange") {         modelandview.addobject("fruittype", 2); //this want pass success ajax call.     }      modelandview.setviewname("fruitgarden");     return modelandview; }

and jsp view ajax call this:

$("#checkfruitbtn").click(function () {     var fruitinput = $("input[name=fruitinput]").val();     $.ajax({         type: 'post',         url: 'checkfruit',         data: 'fruitinput=' + fruitinput,         success: function () {             var fruittype= ${fruittype}; //i want attribule of "fruittype" variable set in controller. things went wrong.             if (fruittype == 1) {                 alert("this apple.");             } else if (fruittype == 2) {                 alert("this orange.");             }             window.location.href = "/someurl";         }     }); });

in above example. when click button "checkfruitbtn", send ajax call controller "checkfruit". , in controller, i'll set variable "fruittype" send success ajax call function. in success ajax call function, i'll value of "fruittype" variable check , show alert message according value... but, things aren't going planned.

my question is, there possible way of getting value of "fruittype" variable? i've searched getting method still can't find 1 fitted in case. i'm terribly sorry if question have been asked before.

thanks in advance!

with annotation @responsebody, springmvc converts returned object response body using httpmessageconverter.

modelandview involves command object , view name.

so can use modelandview jsp page , use el evaluate command object values. use @responsebody, springmvc return strings.

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
