本文實例為大家分享了js仿新浪微博消息發布的具體代碼，供大家參考，具體內容如下
<!DOCTYPE html><html><head><meta charset="UTF-8"><title>仿新浪微博消息發布功能</title><style>*{margin: 0; padding: 0;}#div1{width: 400px; height: 400px; border: 1px solid; margin:10px auto; position: relative;overflow: hidden;}#ul1 li{border-bottom: 1px #999 dashed; padding: 4px; list-style: none;filter: alpha(opacity:0);opacity: 0;}</style><script src="js/chuan.js"></script></head><body> <textarea rows="5" cols="30" id="txt1"value=""></textarea> <input type="button" id="btn1" value="發布" /> <div id="div1"> <ul id="ul1"></ul> </div><script>var oUl=document.getElementById('ul1');var oTxt1=document.getElementById('txt1');var oBtn=document.getElementById('btn1');oBtn.onclick=function(){var oLi=document.createElement('li'); oLi.innerHTML=oTxt1.value; oTxt1.value=''; if(oUl.children.length>0) { oUl.insertBefore(oLi,oUl.children[0]); } else { oUl.appendChild(oLi); } var iHeight=oLi.offsetHeight; oLi.style.height=0; move(oLi,{height:iHeight},function() { move(oLi,{opacity:100}); });}</script></body></html>chuan,js為之前寫的完美運動框架：
function getstyle(obj,name) {if(obj.currentStyle){return obj.currentStyle;}else{return getComputedStyle(obj,false)[name];} } function move(obj,json,fnEnd){clearInterval(obj.timer);obj.timer=setInterval(function(){ var bBox=true;//假設所有值都已經到了 for(var strr in json) { if(strr=='opacity') { var cur=Math.round(parseFloat(getstyle(obj,strr))*100); } else { var cur=parseInt(getstyle(obj,strr)); } var speed=(json[strr]-cur)/10; speed=speed>0?Math.ceil(speed):Math.floor(speed); if(cur!=json[strr]) bBox=false; if(strr=='opacity') { obj.style.filter='alpha(opacity:'+(cur+speed+')'); obj.style.opacity=(cur+speed)/100; } else { obj.style[strr]=cur+speed+'px'; } } if(bBox) { clearInterval(obj.timer); if(fnEnd)fnEnd(); }},30);};以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
