java - How to access javascript variable in a jsp page -


i want access javascript code in jsp file. have included javascript file in jsp page.

javascript file abc.js has following line of code:

var dynamicdiv = 'your leave approved';

and jsp file aaa.jsp has

<script src="abc.js"> </script>     <% string st = "<script> dynamicdiv </script>"; out.println(" value = " + st); %>

javascript variable on client side, jsp variables on server side, can't access javascript variables in jsp.

you can store values in hidden field somthing this

clinet side:

<script type="text/javascript"> var element = document.getelementbyid("myinput"); element.value = "some value here"; </script> <form action="yourfile.jsp" method="post"> <input id="myinput" type="hidden" value="" /> <input type="submit" /> </form>

server side(yourfile.jsp): 

<% if (request.getparameter("myinput") != null) { %>  value: <%=request.getparameter("myinput")%> <%    }  %>

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
