wrote a round show, passed the test, a little ugly.
function autoPlay(){
var myimg = document.getElementById("loopimg");
if(myimg.src.match("i1.png")){
myimg.src = "image/i2.png";
}
else if(myimg.src.match("i2.png")){
myimg.src = "i3.jpg";
}
else if(myimg.src.match("i3.png")){
myimg.src = "i4.jpg";
}
else if(myimg.src.match("i4.png")){
myimg.src = "i5.jpg";
}
else{
myimg.src = "image/i1.png";
}
}
setInterval(autoPlay,1000)
rewritten as an array also passed.
var imgs = ["image/i1.png","image/i2.png","image/i3.png","image/i4.png","image/i5.png"];
var imgsIndex = 0;
function autoPlay(){
if(index == imgs.length-1){
imgsIndex = 0;
}
var myimg = document.getElementById("loopimg");
myimg.src = imgs[imgsIndex];
imgsIndexPP;
}
setInterval(autoPlay,1000)
my idea: rewrite the broadcast in for loop. During each cycle, sleep for one second,
searched the data and found that the sleep function of js is not easy to implement.
