Javascript: using the replace method on hex or dec character using the hex or dec value itself -


i have html table sorting function sort in ascending or descending order column. show using down- , up- pointing small triangles hex code x25be; , x25b4; respectively.

the problem cannot replace these hex characters using replace method. can using character follows: mystring.replace('▴',''); not possible because javascript code generated , ▴ character cannot used in generating code.

it ok me use decimal codes #9662; , #9652; , if helps. see code sorttable function expressions tried, including suggestions post: javascript replaceing special characters

<html> <meta charset="utf-8"> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <head>   <script type="text/javascript">     function sorttable(id,n) {       table = document.getelementbyid(id);       //i skipping sorting here.        //the question is: how replace hex or dec characters?       var ths = table.getelementsbytagname('th')       (i = 0; < ths.length; i++) {         //not working         ths[i].innerhtml = ths[i].innerhtml.replace(' &#x25be;','');         ths[i].innerhtml = ths[i].innerhtml.replace(' &#x25b4;','');         //also not working                 //https://stackoverflow.com/questions/4347366/javascript-replaceing-special-characters         ths[i].innerhtml = ths[i].innerhtml.replace(/\x25be/g,'');         ths[i].innerhtml = ths[i].innerhtml.replace(/[\xae\xfc]/g,'');         //this works cannot use it!         //ths[i].innerhtml = ths[i].innerhtml.replace(/[▴▾]/g,'');         //mimick switching down-pointing small triangle up-pointing 1           if (i == n) {           ths[i].innerhtml = ths[i].innerhtml + ' &#x25b4;';         }       }     }   </script> </head> <body> <table id="tableid">   <tbody>     <tr>       <th onclick="sorttable('tableid',0)">col1 &#x25be;</th>       <th onclick="sorttable('tableid',1)">column 2 </th>     </tr>     <tr>       <td>a</td>       <td>100</td>     </tr>     <tr>       <td>b</td>       <td>20</td>     </tr>     <tr>       <td>c</td>       <td>50</td>     </tr>   </tbody> </table> </body> </html>

as @kelvin sherlock wrote in comment using \u25be works: .replace(' \u25be;','');

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 ...
