php - Javascript Ajax - Contact form does not display prompts and send button doesn't work -


i looking on different examples contact form sent using javascript / ajax. solutions don't seems work. i'm trying rewrite existing chunk of code. here left (with few of own modifications).

i don't quite understand functionality going wrong. send button nothing, not send email , goes top of page.

javascript: 

<script type="text/javascript">     $('#submit').click(function(){         var name = $("#name").val();         var email = $("#email").val();         var phone = $("#phone").val();         var message = $("#message").val();         if (name == "") {            $('.errormess').html('<div class="alert alert-warning"><strong>please insert name</strong></div>');             return false;         }         if (email == "") {            $('.errormess').html('<div class="alert alert-warning"><strong>please insert email</strong></div>');             return false;         }         if (phone == "") {            $('.errormess').html('<div class="alert alert-warning"><strong>please insert phone number</strong></div>');             return false;         }         if (message == "") {            $('.errormess').html('<div class="alert alert-warning"><strong>please insert text</strong></div>');             return false;         }         $.ajax({             type: "post",             url: 'contact-us.php',             data: 'name='+$("#name").val() +              'email='+$("#email").val() +              'phone=' + $("#phone").val()              + 'message=' + $("#message").val(),             datatype: "html",           success: function(data) {           if (data == 0) {           $('.errormess').html('<div class="alert alert-success"><strong>your query submited successfully</strong></div>');             } else {                  $('.errormess').html('<div class="alert alert-danger"><strong>failed send email</strong></div>');              }           }          });         return true;         });

this contact-us.php: 

<?php $name=$_post['name']; $email=$_post['email']; $phone=$_post['phone']; $message=$_post['message']; $to = "help@belladonnait.com"; $subject = "email user";  $message = " <html> <head> <title>email user</title> </head> <body> <p>this email contains user requirement</p> <table> <tr> <th>name</th> <th>email</th> <th>phone</th> <th>message</th> </tr> <tr> <td>".$name."</td> <td>".$email."</td> <td>".$phone."</td> <td>".$message."</td> </tr> </table> </body> </html> ";  $headers = "mime-version: 1.0" . "\r\n"; $headers .= "content-type:text/html;charset=utf-8" . "\r\n"; $headers .= 'from: <webmaster@example.com>' . "\r\n"; $headers .= 'cc: myboss@example.com' . "\r\n";  $ok=mail($to,$subject,$message,$headers); if ($ok) {     echo "1"; } else{     echo "0"; } ?>

i think the problem data in ajax. either send in object {name:$("#name").val(),email:$("#name").val(),...} or add "&" in-front of each key ( '&name='+$("#name").val() + '&email='+$("#email").val() ). hope helps

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
