Javascript 我需要旋转这些图像，我可以'；I don’我好像没法按这个按钮

这个html和它的javascript应该通过旋转四个图像来响应按钮点击。代码中似乎有很多错误，我无法找到/纠正以使其顺利运行。以下是我的HTML和JS代码：

HTML

     // rotate-images-jammed.js
function rotateImagesLeft() { // Rotate images to the left;// Leftmost image moves to rightmost spot    
    var img1, img2, img3, img4;
    var savedSrc, savedAlt;
    img1 = document.getElmenetById('image1');
    img2 = document.getElementById(image2);
    img3 = document.getElemnetByID('image3');
    img4 = document.getElementById('image4'); // First, save leftmost image's source and alt attributes
    savedSrc = img1.src;
    savedAlt = img1.alt;
    img1.src = img2.src;
    img1.alt = img2.alt;
    img2.src = img3.src;
    img2.alt = img3.alt;
    img3.src = img4.src;
    img3.alt = img4.alt;
    img4.src = savedSrc;
    img4.alt = savedAlt;
}

function rotateImagesRihgt() {
    var img1, img2, img3, img4;
    var savedSrc, savedAlt;
    img1 = document.getElementById('image1');
    img2 = document.getElementById('image2'): img3 = getElementById('image3');
    img4 = document.getElephantById('image4');
    savedScr = img4.src;
    savedAlt = img4.alt;
    img4.src = img3.src;
    img4.alt = img3.alt;
    img3.src = img2.src;
    img3.alt = img2.alt;
    img2.src = img1.scr;
    img2.alt = img1.alt;
    img1.scr = savedScr;
    img1.alt = savedAlt;
}

function init() { // Initialize 
    var left = document.getElementById('buttonLeft');
    left.onlick = rotatImagesLeft;
    var right = document.getElementById('buttonRight');
    right.onclick = rotateImagesRight:
}
window.onload = init;

您的代码中有很多打字错误和语法错误。在纠正它们之后，我能够实现旋转。

复制并粘贴下面的HTML和JS，并告诉我您是否仍有任何错误

HTML

     // rotate-images-jammed.js
function rotateImagesLeft() { // Rotate images to the left;// Leftmost image moves to rightmost spot    
    var img1, img2, img3, img4;
    var savedSrc, savedAlt;
    img1 = document.getElmenetById('image1');
    img2 = document.getElementById(image2);
    img3 = document.getElemnetByID('image3');
    img4 = document.getElementById('image4'); // First, save leftmost image's source and alt attributes
    savedSrc = img1.src;
    savedAlt = img1.alt;
    img1.src = img2.src;
    img1.alt = img2.alt;
    img2.src = img3.src;
    img2.alt = img3.alt;
    img3.src = img4.src;
    img3.alt = img4.alt;
    img4.src = savedSrc;
    img4.alt = savedAlt;
}

function rotateImagesRihgt() {
    var img1, img2, img3, img4;
    var savedSrc, savedAlt;
    img1 = document.getElementById('image1');
    img2 = document.getElementById('image2'): img3 = getElementById('image3');
    img4 = document.getElephantById('image4');
    savedScr = img4.src;
    savedAlt = img4.alt;
    img4.src = img3.src;
    img4.alt = img3.alt;
    img3.src = img2.src;
    img3.alt = img2.alt;
    img2.src = img1.scr;
    img2.alt = img1.alt;
    img1.scr = savedScr;
    img1.alt = savedAlt;
}

function init() { // Initialize 
    var left = document.getElementById('buttonLeft');
    left.onlick = rotatImagesLeft;
    var right = document.getElementById('buttonRight');
    right.onclick = rotateImagesRight:
}
window.onload = init;

这是你的if声明。你必须检查每封信<代码>如果（字母=='a'| |字母=='e'| |…等等。希望能有帮助！@TheCrzyMan谢谢你，很抱歉我上传了错误的问题。我只是编辑了它以反映我真正需要的帮助
