javascript （用setTimeout而非setInterval）
简介复制代码 代码如下: var num = 0; var max = 10; function incrementNumber() { num++; //if the max has not been reached, set another timeout if (num < max) { setT
复制代码 代码如下:
var num = 0;
var max = 10;
function incrementNumber() {
num++;
//if the max has not been reached, set another timeout
if (num < max) {
setTimeout(incrementNumber, 500);
} else {
alert(“Done”);
}
}
setTimeout(incrementNumber, 500);
如果用setInterval 可能出现 下次调用会在前一次调用前调用 （
True intervals are rarely used in production environments because it ' s possible that one interval will begin before the previous one has finished executing）
