我试图在我的部分代码之间设置超时，但语法忽略了暂停

Question

alert ("hi")
alert("i will generate a random number on the screen and then  seconts tell you it and write it on the screen")
function e() {Math.Random()}
var number45654=Math.Random()
document.write (number45654)
function exec() {
    for(var i=0;i<5;i++) {
        setTimeout(function() {
            console.log(new Date());   //It's you code
        },(i+i+1)*1000);
    }
}
alert(number45654)
function exec() {
    for(var i=0;i<5;i++) {
        setTimeout(function() {
            console.log(new Date());   //It's you code
        },(i+i+1)*1000);
    }
}

我认为 document.write 或 document.open() 可能会忽略超时，但我不确定

Answer 1

看来你想做的是：

// Function declarations should generaly come first
function exec() {
    for(var i=0;i<5;i++) {
        setTimeout(function() {
            console.log(new Date());
        }, (i+i+1)*1000);
    }
}

alert("hi etc.")

// Note that it is Math.random, not Math.Random
var num = Math.random()
document.write(num)
alert(num)

// Note that you should call the function, not re-declare it
exec()
