html - How to attach div to bottom of textarea using jquery -


i can have multiple html textarea boxes on web page , when textarea receives focus, i'd display (or create) div underneath it. when focus leaves want hide (or destroy) div. when different textarea receives focus want same thing occur. few details:

  1. the textareas can variety of widths , heights
  2. the div attached underside of textarea fixed , unchanging, 200px width , 40px high. won't change regardless of height/width of textarea above it.
  3. the user doesn't need interact div, , in fact shouldn't. displaying "x of xx characters used" or similar. it's display only, contents of div continuously change user types. (hopefully won't remove focus text area , hide div)
  4. only 1 "div-underneath-textarea" ever visible @ time. means 1 div need exist. , can created on fly if that's easiest.
  5. div should created when textarea receives focus.
  6. div should destroyed when textarea loses focus.
  7. contents of div must change each time key pressed.
  8. the div needs precisely anchored underneath textara.

what straightforward way achieve jquery? i'm thinking dynamically created (and later destroyed) div ideal, unless it's problematic reason.

i need dynamic div creation/destruction upon focus/blur, , anchoring of div underside of textarea.

thanks in advance.

you can use insertafter() insert div after textarea on focusin. on focusout can remove div. i'm not sure want happen when content of div must change each time key pressed. if want display content of textarea can use keyup function , display text or something. if specify want happen better can better out. said can following:

//inserts div under textarea  $('textarea').on('focusin', function(){    $('<div class="added-div">added div</div>').insertafter(this);  });  //removes added div , clears textarea  $('textarea').on('focusout', function(){    $('.added-div').remove();    $(this).val('');  });  //updates added div textarea content  $('textarea').keyup(function () {    var textareacontent = $(this).val();    $('.added-div').html(textareacontent);  });
textarea{    display:block;    margin:10px 0;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <textarea></textarea>  <textarea></textarea>  <textarea></textarea>  <textarea></textarea>

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
