javascript - MutationOberserver should observe iframes -


currently use observer attach click event first event handler dynamically created elements. unfortunately doesn't work elements within dynamically created iframe.

elementobserver = new mutationobserver(function (mutations) {   mutations.foreach(function (mutation) {     $(mutation.target).bindfirst('click', my.callback.function);   }); });  elementobserver.observe(document.body, {childlist: true, subtree: true});

the bindfirst() function looks like:

$.fn.bindfirst = function(name, fn) {    this.on(name, fn);    this.each(function() {       var handlers = $._data(this, 'events')[name.split('.')[0]];       var handler = handlers.pop();       handlers.splice(0, 0, handler);    }); };

but my.callback.function won't triggered within iframe. how can solve problem my.callback.function gets triggered in iframe well.

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...

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
