我有 2 个没有一起工作的 javascript。它们都单独工作，但放在一起时只有一个工作。我就是这样称呼他们的



    window.onload = initImages;
    window.onload = countdown(year,month,day,hour,minute);

如果我把“window.onload = initImages;” 在“倒计时”之后，只有图像工作，如果倒计时在图像之后保持这种状态，那么只有倒计时工作。

// JavaScript Document


function initImages() {
    for (var x = 0; x < document.images.length; x++)
    {
        document.images[x].onclick = povecana;
    }
}
function povecana() {

    dir = "images/" + this.id + ".jpg";

    if (undefined != window.proz)
    {
        proz.style.opacity = 0.6;
    }
    proz = document.getElementById(this.id);
    proz.style.opacity = 1;

    slika = document.getElementById("odabranaSlika");   

    slika.style.display= "block";
    slika.innerHTML='<img src='+ dir +' " width="100%" height="450px" />';

    jabuke = document.getElementById("default");
    jabuke.style.display= "none";   

    tekst = document.getElementById("tekstOdabrane");
    tekst.style.display = "block";

    if (this.id=="slika1")
    tekst.innerHTML="Idared je američka sorta nastala 1935.";
    else (this.id=="slika2")
    tekst.innerHTML="Fuji je zasigurno jedna od atraktivnijih";
}

window.onload = function() {
    initImages();
    countdown(year,month,day,hour,minute);
}

它们正在被覆盖。您不能将两个值分配给一个变量！

例如，

x = 5;
x = 10;

当然x会10。好吧，对你来说也是一样的：就像你的函数window.onload一样x，数字就像你的函数。

1 
window.onload = func1;
window.onload = func2;

在这种情况下，总是会调用 func 2，因为您在第二条语句之后将 onload 处理程序从 func1 更改为 func2；

尝试

window.onload = function(){
  func1();
  func2();
}
