html - Hide/Show element if IE - Javascript -


i working script pops alert if user or isn't using ie.

instead of this, i'd show or hide div element in page.

i have tried unsuccessfully here: http://fiddle.jshell.net/shhv1lx3/2/

working alert demo here: http://fiddle.jshell.net/shhv1lx3/3/

function getieversion() {    var sagent = window.navigator.useragent;    var idx = sagent.indexof("msie");      // if ie, return version number.    if (idx > 0)       return parseint(sagent.substring(idx+ 5, sagent.indexof(".", idx)));      // if ie 11 updated user agent string.    else if (!!navigator.useragent.match(/trident\/7\./))       return 11;      else      return 0; //it not ie  }    var e = document.getelementbyid(ie);  var e2 = document.getelementbyid(chrome);    if (getieversion() > 0)      alert("this ie " + getieversion());     e.style.display = 'block';     e2.style.display = 'none';  else      alert("this not ie.");     e.style.display = 'none';     e2.style.display = 'block';
<div id="ie">  ie  </div>    <div id="chrome">  chrome  </div>

you should use {} when using if/else statements. optional when there 1 statement, mandatory when there multiple statements. highly suggest using {} always, regardless of number of statements.

you need pass string getelementbyid().

function getieversion() {    var sagent = window.navigator.useragent;    var idx = sagent.indexof("msie");      // if ie, return version number.    if (idx > 0){      return parseint(sagent.substring(idx+ 5, sagent.indexof(".", idx)));    }    // if ie 11 updated user agent string.    else if (!!navigator.useragent.match(/trident\/7\./)){      return 11;    }    else{      return 0; //it not ie    }  }    var e = document.getelementbyid('ie');  var e2 = document.getelementbyid('chrome');    if (getieversion() > 0){     alert("this ie " + getieversion());     e.style.display = 'block';     e2.style.display = 'none';  }  else{     alert("this not ie.");     e.style.display = 'none';     e2.style.display = 'block';  }
<div id="ie">  ie  </div>    <div id="chrome">  chrome  </div>

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
