我有一个setInterval循环.设置为3500毫秒,如下所示:-
I have a setInterval loop. It's set to 3500 milliseconds, like so:-
var loop = setInterval(function() { /*stuff*/ }, 3500);如果发生某种情况,在填充"的某一点上,我想强制循环的新迭代,并且在3500毫秒内不等待.那怎么可能?是继续吗,还是我只需要以不同的方式制定流程?
At one point in 'stuff' if a certain situation occurs, I want to force a new iteration of the loop and NOT WAIT for the 3500 milliseconds. How is that possible? Is it continue or do I just need to frame the process differently?
推荐答案您可以尝试使用setTimeout而不是setInterval编写匿名自调用函数:
You could try writing an anonymous self-calling function using setTimeout instead of setInterval:
var i = 0; (function() { // stuff i++; if (i % 2 == 0) { // If some condition occurs inside the function, then call itself once again // immediately arguments.callee(); } else { // otherwise call itself in 3 and a half seconds window.setTimeout(arguments.callee, 3500); } })(); // <-- call-itself immediately to start the iteration
更新:
UPDATE:
由于在注释部分表达了对arguments.callee用法的分歧,因此,使用命名函数可以实现相同的目的:
Due to a disagreement expressed in the comments section against the usage of arguments.callee, here's how the same could be achieved using a named function:
var i = 0; var doStuff = function() { // stuff i++; if (i % 2 == 0) { // If some condition occurs inside the function, then call itself once again // immediately doStuff(); } else { // otherwise call itself in 3 and a half seconds window.setTimeout(doStuff, 3500); } }; doStuff();更多推荐
