suggestion for _wait: stop execution if condition returns false

nickleus

i wish there was an additional "_wait(maxTime, condition)" function that would stop execution if condition returns false.

as of now, it seems as if "wait + condition" continues execution no matter the outcome of "condition", which makes it an "OR" test, but my suggestion would be for an "AND" test, i.e.:
wait, up until maxTime is reached, and if condition is still false, then stop execution.

i want this because of network/server response timing issues, specifically related to ajax operations.

Hi nickleus

i got this snippet

function waitForElement($element, $time) {
  var $waitTime=500;
  var $maxI = $time/$waitTime;
  while (_condition(!(_exists($element)))) {
    _wait($waitTime);
    $maxI--;
    if ($maxI<=0) throw "Waited too long, stopping execution";
  }
}

which could be modified to

function waitForSomeThing($condition, $time) {
  var $waitTime=500;
  var $maxI = $time/$waitTime;
  while ($condition()) {
    _wait($waitTime);
    $maxI--;
    if ($maxI<=0) throw "Error";
  }
}

// which can be used like
function testSomething($b) {
  return $b;
}
waitForSomeThing(testSomething, 10000);

could this help?
