如标题所述,仅当某些条件完成后,如何才能运行其余代码(位于主函数下方)?例如:
function foo() {
count = 0;
var interval = setInterval(function() {
count++;
if (count == 10) {
clearInterval(interval);
console.log('Done');
}
}, 1000);
}
foo();
console.log("It should display after Foo() is done");
最佳答案
您应该为此使用promise
。然后您的代码将如下所示
function foo() {
return new Promise(function(resolve , reject){
count = 0;
var interval = setInterval(function() {
count++;
if (count == 10) {
clearInterval(interval);
console.log('Done');
resolve();
}
}, 1000);
})
}
foo().then(function(){
console.log("It will be displayed after Foo() is done");
})
