html and javascript password: how to change display of an element if the password is correct? -


i need make password protected image in html of javascript, means, if enter correct password, image appear.i'm beginner, can't find error in this. don't know if if code written, thankful if help.

html:

    <img src="..." id="smiley"/>      <form>          picture password protected<br>enter password:<br>          <input type="password" name="password" id="password">          <input type="button" onclick="funcpass( );" value="ok">      </form>

javascript:

    var password = getelementbyid("password").value;     function funcpass(password.value) {         if (password.value == "smiley")         {             document.getelementbyid("smiley").style.display = "block";         }         else         {             password.value = " ";         }      }

in css changed image display property none

your code password needs in function itself. you're getting value twice (the value of value). try this:

function funcpass() {     var password = document.getelementbyid("password").value;     if (password == "in darkened room")     {         document.getelementbyid("smiley").style.display = "block";     }     else     {         password = "";     }  }

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
