full code above

i'm trying make random nba draft lottery 8 teams (using array 8 images) reveals image of team 8th pick on button click , removes array list leaving 7 remaining teams , on. i dont want remove image, item option array when click following 7 buttons. trying use 8 list images in array, , 8 buttons numbered 1-8. want similar nba's draft lottery if has code formula percentages great.

the odds each team chances 1st pick = 25%, 2nd pick 16.4%, 3rd pick 16.4%, 4th pick 16.3%, 5th pick 9.4%, 6th pick 6.6%, 7th pick 4.4%, 8th pick 2.7%, here have now. can't seem button reveal random team. fantasy league not professional site or anything.

function teams() {   var ateams = [];   ateams[0] = "<img src='http://i.imgur.com/kowpajr.png' height='100' width='100' alt='cavs'>";    ateams[1] = "<img src='http://i.imgur.com/kowpajr.png' height='100' width='100' alt='suns'>";    ateams[2] = "<img src='http://i.imgur.com/kowpajr.png' height='100' width='100' alt='rockets'>";    ateams[3] = "<img src='http://i.imgur.com/kowpajr.png' height='100' width='100' alt='nuggets'>";    ateams[4] = "<img src='http://i.imgur.com/kowpajr.png' height='100' width='100' alt='celtics'>";    ateams[5] = "<img src='http://i.imgur.com/kowpajr.png' height='100' width='100' alt='raptors'>";    ateams[6] = "<img src='http://i.imgur.com/kowpajr.png' height='100' width='100' alt='thunder'>";    ateams[7] = "<img src='http://i.imgur.com/kowpajr.png' height='100' width='100' alt='warriors'>";   var rdmteams = math.floor(math.random() * ateams.length);   document.getelementbyid("table").value = ateams[rdmteams]; }

this no means perfect. needs formatting of code, asked believe. there html need on fiddle.

/* * create listener button click */ var table = document.getelementbyid("table"); table.addeventlistener('click', function(event) {     if (event.target.nodename == "button") {         // div corresponding button clicked         var thispickdiv = document.getelementbyid(event.target.id.replace("btn", "div"));         var rdmnum = math.floor(math.random() * ateams.length);         thispickdiv.innerhtml = ateams[rdmnum];         ateams.splice(rdmnum, 1);     } });

the image stays on page. hope meant not removing image. if not can done having 2 arrays (one teams , other img sources) not know benefit afford you.

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
