Question

我编写的用于更改网站标题图片的功能遇到麻烦。它根本什么也没做。没有错误讯息... 我想使其像一个自动滑块。

function Austausch (){
    var quelle = document.getElementById("bild1").src; 

    switch(quelle){

        case "img/Slider/allesmoeglich.jpg": 
        document.getElementById("bild1").src = "img/Slider/begeister.jpg";
        break; 
        case "img/Slider/begeister.jpg": 
        document.getElementById("bild1").src = "img/Slider/modern.jpg";
        break; 
        case "img/Slider/modern.jpg": 
        document.getElementById("bild1").src = "img/Slider/kreativ.jpg";
        break; 
        case "img/Slider/kreativ.jpg": 
        document.getElementById("bild1").src = "img/Slider/professionell.jpg";
        break; 
        case "img/Slider/professionell.jpg": 
        document.getElementById("bild1").src = "img/Slider/allesmoeglich.jpg";
        break; 
    }


setInterval(Austausch, 3000);

非常感谢！ console.log才救了我！遇到相同问题的任何人的正确代码：

function Austausch(){
    var quelle = document.getElementById("bild1").src;  

    switch(quelle){
        case "https://marie-joelle-eichmueller.online/img/Slider/allesmoeglich.jpg": 
        document.getElementById("bild1").src = "img/Slider/begeister.jpg";
        break; 
        case "https://marie-joelle-eichmueller.online/img/Slider/begeister.jpg": 
        document.getElementById("bild1").src = "img/Slider/modern.jpg";
        break; 
        case "https://marie-joelle-eichmueller.online/img/Slider/modern.jpg": 
        document.getElementById("bild1").src = "img/Slider/kreativ.jpg";
        break; 
        case "https://marie-joelle-eichmueller.online/img/Slider/kreativ.jpg": 
        document.getElementById("bild1").src = "img/Slider/professionell.jpg";
        break; 
        case "https://marie-joelle-eichmueller.online/img/Slider/professionell.jpg": 
        document.getElementById("bild1").src = "img/Slider/allesmoeglich.jpg";
        break; 
    }

}
setTimeout(Austausch, 3000);

我编写的用于更改网站标题图片的功能没有任何作用
