javascript - Change Div and Body Class on Refresh -


i'm using backstretch plugin apply stretched background image body element.

$("body.apples").backstretch("/apples.jpg"); $("body.oranges").backstretch("/oranges.jpg"); $("body.pears").backstretch("/pears.jpg");

i want body class change on refresh, shows different background images on refresh. i'm trying work out how show related .wrapper div below when page refreshed.

<body class="apples">     <div class="wrapper apples">         <h1>something apples</h1>         <p>some content</p>     </div>      <div class="wrapper oranges">         <h1>something oranges</h1>         <p>some content</p>     </div>      <div class="wrapper pears">         <h1>something pears</h1>         <p>some content</p>     </div> </body>

i've managed .wrapper div change on refresh bit of js:

function randomfromto(from, to) {         return math.floor(math.random() * (to - + 1) + from);     }      function randomfruit() {         var r = randomfromto(1, $('.wrapper').length);         $('.wrapper').hide().eq(r - 1).show();     }      $(document).ready(function() {         randomfruit(); });

i've got working demo here: http://codepen.io/realph/pen/kcetb

for reason, can't work out how make background , .wrapper div change.

any appreciated. in advance.

maybe can if else statement? , need 1 wrapper

if ( $("body").hasclass("yourfruithere") ) { $(".wrapper").html("<h1>something fruit</h1><p>some content</p>");

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
