How can I loop AsyncAjaxRequest in GWT?

This might help you Async calls in gwt execute immediately, and return "later". In your code, the while loop isn't waiting for anything, so you're calling initTable() many many times per second, hence the infinite loop.
Simply create a timer that executes every 10 seconds.
final Timer timer = new Timer() {

        @Override
        public void run() {
              try {
                someService.initTable(new AsyncCallback<SomeObject>() {

                     @Override
                     public void onFailure(Throwable caught) {
                     }

                     @Override
                     public void onSuccess(SomeObject result) {
                         initData(numbersTable, result);
                     }
                   });
                } catch (Exception e) {
                }
        }

};
timer.scheduleRepeating(10000);

PHP while loop for HTML Generation: Should I Check Array values at each While Loop Iteration or use Post-Loop String Pro


Tag : php , By : Salikh

it should still fix some issue I'm working on a PHP-written html calendar that writes each day of the month inside a while loop. , Here's another solution:
$day = 1;
$strings = array();
while($day < 31) {
    if (array_key_exists($day, $array)) {
        $strings[$day] = $array['$day'] . " spots available";
    } else {
        $strings[$day] = "No spots available for this date";
    }
    $day += 1;
}
foreach ($strings as $day => $string) {
    echo '<td title="' . $string . '">' . $day . '</td>';
}

Triple nested loop (while loop insde of for loop inside of while loop)

Does that help If you want m1 to be the cumulative list of means, then the last line needs to be indented to be inside the final while block.
while d <335:     
    d = d + 1     
    y = fpsd[d]     
    y1 = y1 + [y]       
    m = np.mean(y1)
    m1 = m1 + [m]

My loop works like this: loop, script, loop. I want this: loop, loop, code. The ForgottenServer 0.3.6

hop of those help? Can you just move the "set storage" to a second loop after the first? That's the only way that you'll be able to send all of the messages before doing any of the set storage calls.
for _, pid in ipairs(getPlayersOnline()) do 
  if getCreatureStorage(pid, tmp[i].storeDamage) > -1 then 
    doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, getPlayerName(pid)..': '..getCreatureStorage(pid, 11005))
  end
end
for _, pid in ipairs(getPlayersOnline()) do 
  doCreatureSetStorage(pid, tmp[i].storeDamage, -1) 
end

hope this fix your issue I have several row in a table in db and every row related with three tables and every table has many rows. when i loop main table rows i also loop three tables rows now if one of tables has a content in row then i want to prevent showing entire sub that loop only which contain a value. , This method uses relationship count comparison.

public function classWiseResult(Request $request){
    $students = Students::where('class',$request->class)

        }])
        ->withCount('firstTerm as firstTermAllCount')
        ->withCount(['secondTerm as secondTermPromoted' => function($q) {
