图片js动效代码_javascript如何实现动态效果

『壹』 js图片跳动

functionshow(){
varimgid=document.getElementById("imgid");
	if(imgid.style.visibility=="visible")
		imgid.style.visibility="hidden";
	else
		imgid.style.visibility="visible";
		
	setTimeout('show()',300);
}

HTML：

<button onclick="show()">按下图片会闪动</button>

不知道你是不是这个意思发现有点没读懂你想要的东西

『贰』求一个简单的点击图片放大缩小的JS代码

1、准备好需要用到的图标。

3.页面调用：

$('.lbCon.lbBox.lbList').imgScroll({
firstDiv:'.lbCon.lbBox',
scrollBox:'.lbCon.lbBox.lbList',
scrollImgBox:'.lbCon.lbBoxul',
botPrev:'.lbCon.lbPrev',
botNext:'.lbCon.lbNext',
changeType:"slide",
thumbNowClass:'on',
thumbOverEvent:true,
changeTime:5000,
ImgBoxMar:0,
flag:false
});

4.至于鼠标滑过显示左右按钮,可以这么写（思路:css默认隐藏左右按钮，鼠标滑过显示左右按钮，划出隐藏，需要引入jquery.js）

$(function(){
$(".wj_jdt_1").bind("onmouseover",function(){
$(".ctr_btn").show();
}).bind("onmouseout",function(){
$(".ctr_btn").hide();
})
})

大体是这么个意思，至于怎么延伸在你
