Question

我正在为我的网站制作标题，我想让它像幻灯片一样。问题是图像不会改变。它仅显示1张图像，其余图像不会显示。代码：

＆＃13;

//Array with the paths to the images
var image = new Array("img/header/header1.png", "img/header/header2.png", "img/header/header3.png");

//imageNumber to change the image, and imageLenght for the array lenght - 1 
var imageNumber = 0;
var imageLength = image.length -1;

//Call changeImage()
changeImage();

//Function to change the image
function changeImage() {

	//use strict because I use dreamweaver and it needs that(I don't know why)
	"use strict";
	//Add 1 to imageNumber for choosing a image(in "document.slideshow.src = image[imageNumber];")	
	imageNumber++;

	//Check if image number is not below 0 or above the array index
	if(imageNumber < 0) {

		imageNumber = imageLength;

	} else if(imageNumber > imageLength) {

		imageNumber = 0;

	}

	//Change the image
	document.header.src = image[imageNumber];
	
	//recalling every second
	setTimeout(changeImage, 1000);

}
