This article describes the method of js to trigger the image jitter effect by triggering the mouse. Share it for your reference. The specific implementation method is as follows:
Copy the code as follows: <html>
<head>
<title>Mouse triggers picture jitter effect</title>
<style>
.shakeimage{
position:relative
}
</style>
<script language="JavaScript1.2">
//configure shake degree (where larger # equals greater shake)
var reflector=3
/////////DONE EDITTING////////////////
var stopit=0
var a=1
function init(which){
stopit=0
shake=which
shake.style.left=0
shake.style.top=0
}
function rattleimage(){
if ((!document.all&&!document.getElementById)||stopit==1)
Return
if (a==1){
shake.style.top=parseInt(shake.style.top)+rector
}
else if (a==2){
shake.style.left=parseInt(shake.style.left)+rector
}
else if (a==3){
shake.style.top=parseInt(shake.style.top)-rector
}
else{
shake.style.left=parseInt(shake.style.left)-rector
}
if (a<4)
a++
else
a=1
setTimeout("rattleimage()",50)
}
function stoprattle(which){
stopit=1
which.style.left=0
which.style.top=0
}
</script>
</head>
<body bgcolor="#F7F7F7">
<p align="center">
<img src=/images/skinslogo.gif onMouseover="init(this);rattleimage()" onMouseout="stoprattle(this)">
<br>
Move the mouse to see the effect! </p>
</body>
</html>
I hope this article will be helpful to everyone's JavaScript programming.
