javascript - Unable to click button programatically in UIWebView (Webpage) -


i trying programatically click on single button on webpage in uiwebview using

nsstring *jsstat = @"document.getelementsbyname('btn btn-info')   [0].click()"; [webview stringbyevaluatingjavascriptfromstring:jsstat];

but button has not been clicked programatically. button class name "btn btn-info" , button's properties are

<input type="submit" value="click me" class="btn btn-info">

and complete page is

<form action="https:www.googleabc.com"post"> <input type=hidden name=id value="myvalue" /><input type=hidden name=style value=stl:18/> <input type="submit" value="click me" class="btn btn-info">

missing here? or there better solution this?

it should getelementsbyclassname not getelementsbyname:

document.getelementsbyclassname('btn btn-info')[0].click()

working example: 

document.getelementsbyclassname('btn btn-info')[0].click()
<input type="submit" value="click me" class="btn btn-info" onclick="console.log('clicked!')">

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
