Repeat Javascript/jQuery until specific outcome -


I currently have the following code that appears in a noodle list and selects random objects. I want to make sure that the 'Li' line is not selected twice, or even better, do not choose to repeat, unless all of them are selected. 

  var list = $ ('# headshot took: view'). ToArray (); Var elemlength = list.length; Var randomitem = list [Math.floor (* MathML) *;

Full code: 

  Function Soft Home PageAgentationHeadshots () { Var fullList = [1,2,3,4,5,6,7,8,9, 10]; Window.setInterval (function () {var random = fullList.slice (0) .sort (function () {return .5 - Math.random ();}); $ ('# headshots li'). Each (function ((= \ D + /, '')); Random = $ .grep (random, function) { Return value!) =) I;});}); var list = $ ('# headshots li: view'). ToArray (); var elemlength = list.length; var randomitem = list [Math.floor (mathematics. ) * Elemlength)]; $ (Random number) CSS ({'background-image': 'url ("' full redundant path + 'image / headshot / headshot-' + random [0] + '.jpg")'});}, 3000); }

Added Bella:

remove random item Let's list variable, then it can not be selected again.
Take a look at this Bela where I use an interval to randomly select each item 

  var list = $ ('# Headshots li: visible '); Var Loop = Set Interval (dot, 500); Function Chart () {if (list.length) {randomitem = list.splice (Math.floor (math.random (* * list.length), 1) $ (randomitem) .css ('background', '# ff0000' ); } And {clear interval (loop); }}

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
