Can you use setInterval to call functions asynchronously?

由 一曲冷凌霜 提交于 2019-12-12 12:19:20
问题 The following code is taken from Project Silk (a Microsoft sample application) The publish method below loops thru an an array of event callBacks and executes each one. Instead of using a for loop setInterval is used instead. The documentation says this allows each subscriber callback to be invoked before the previous callback finishes. Is this correct? I thought the browser would not allow the execution of the function inside the interval to run until all prior executions of it had finished.

setInterval() loop still running after clearInterval() is called

由 不打扰是莪最后的温柔 提交于 2019-12-12 05:49:37
问题 I know that setInterval() returns a unique ID on every loop, and that clearInterval must be called with that ID to kill the loop. I believe my code does this, yet the loop continues to run indefinitely. var refresh = setInterval(function () { $.get(url, function (data) { success: { if (data < 5) { data = 5; } var width = data + "%"; $("#recalculation-progress-bar").css('width', width); if (data > 99) { clearInterval(refresh); $("#recalculation-message").text("Recalculation complete."); } } })
