嘿,我有一个页面,里面有一堆模态图像,当单击其中任何一个时,它会打开相应的图像幻灯片。但是模态使用 js 作为幻灯片,所以有没有办法编辑我的函数,所以每个图像都会打开不同的幻灯片相册,而不仅仅是一遍又一遍地复制相同的函数并更改变量名称,因为这似乎是一种糟糕的方法。
我有一个 JSfiddle 来显示它与 1 张图像以及我所有代码的外观。

showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("demo");
var captionText = document.getElementById("caption");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
captionText.innerHTML = dots[slideIndex-1].alt;
}
我会这样处理它
- 所有幻灯片的 ID。
- 在 HTML mySlidesdiv 中调用函数时输入图像地址和幻灯片的 ID
- 'myFunc(http://image, mySlidesID);
- 然后将
<image>
标签设为SRC="image I Called"
对不起,如果我解释得有点尴尬。
function aFunction(imageURL1,imageURL2,imageURL3,imageURL4, imageID1,imageID2,imageID3, imageID4 ) {
getElementByID(imageID1)
make the src of the image src = imageURL1
}
