Javascript动态伸缩+淡出淡入

Javascript动态伸缩动态伸缩+淡出淡入淡出淡入

一种不错代码应用实例，大家可以根据这个代码，拓宽出更好的代码

//interval变量

var inl = [];

//原始透明度

var opa = 100;

//判断浏览器

var ie = navigator.appName == "Microsoft Internet Explorer" ? "Microsoft Internet Explorer" : "";

mode = "-";

//display是正常的话设置interval缩小

inl['suotu'] = setInterval("suodi('-')", 10);

}else {

mode = "+";

//display是none的话先把display改回去正常，再设置interval放大

$('tmp').style.display = "";

inl['suotu'] = setInterval("suodi('+')", 10);

}

clearInterval(inl['dcdr']);

//更新透明度

ie ? $('tmp').style.filter = "alpha(opacity=" + opa + ")" : $('tmp').style.opacity = opa / 100;

//如果透明度小于等于0或大于等于100

if(opa <= 0 || opa >= 100) {

//停止interval

clearInterval(inl['dcdr']);

}

}

function define(id, a, b, a2, a3) {

if(id == "-") {

if(a >= a3) {

a = a3;

}

}

return a;

}

//缩小或放大

function suodi(opt) {

//速度大于1的话继续除以s，否则等于1

speed = speed > 1 ? speed * 0.862 : 1;

if($('tmp').clientHeight <= speed) {

//隐藏方块

$('tmp').style.display = "none";
