爱站程序员基地js实现点击掉落特效 先看看效果图
话不多说代码
<!DOCTYPE HTML><html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\"><title>无标题文档</title><script src=\"jquery.js\"></script><script>window.onload = function () {var str = \'\';var len = 20;var aDiv = document.getElementsByTagName(\'div\');var timer = null;var num = 0;for ( var i=0; i<len; i++ ) {str += \'<div style=\"width:50px; height:50px; background:red; position:absolute; top:0px; left:\'+ i*60 +\'px;\"></div>\';}document.body.innerHTML = str;document.onclick = function () {clearInterval( timer );timer = setInterval( function (){DM( aDiv[num], \'top\', 23, 500 );num ++;if ( num === len ) {clearInterval( timer );}}, 100 );};};</script></head><body></body></html>
我这里引用了封装方法
function DM( obj, attr, dir, target, endFn ) {dir = parseInt(getStyle( obj, attr )) < target ? dir : -dir;clearInterval( obj.timer );obj.timer = setInterval(function () {var speed = parseInt(getStyle( obj, attr )) + dir; // 步长if ( speed > target && dir > 0 || speed < target && dir < 0 ) {speed = target;}obj.style[attr] = speed + \'px\';if ( speed == target ) {clearInterval( obj.timer );/*if ( endFn ) {endFn();}*/endFn && endFn();}}, 30);}
