JS實現簡單的鍵盤打字的效果，js鍵盤打字
以代碼形式實現過程分析：
<html><head><title>打字效果</title><meta http-equiv="Content-Type" Content="text/html;charset=gb2312" /><style type="text/css">body{ font-size:14px; font-color:#purple; font-weight:bolder;}</style></head><body>最新內容: <a id = "Hotnews" href="" target="_blank"> </a> <script language="javascript"> var NewsTime = 2000; //每條資訊完整出現後停留時間 var TextTime = 100; //每條資訊中的字出現的間隔時間 var newsi = 0; var txti = 0; var txttimer; //調用setInterval的傳回值，用於取消對函數的周期性執行 var newstimer; var newstitle = new Array(); //以數組形式儲存每個資訊的標題 var newshref = new Array(); //以數組形式儲存資訊標題的連結 newstitle[0] = "歡迎來到我的部落格"; //顯示在網頁上的文字內容和對應的連結 newshref[0] = "http://www.bkjia.com/guihailiuli/"; newstitle[1] = "http://www.bkjia.com/guihailiuli/"; newshref[1] = "http://www.bkjia.com/guihailiuli/"; newstitle[2] = "部落格園歡迎你哦"; newshref[2] = "http://www.bkjia.com"; newstitle[3] = "ByeBye~~"; newshref[3] = "http://www.bkjia.com"; function shownew(){ hwnewstr=newstitle[newsi]; //通過newsi傳遞，依次顯示數組中的內容 newslink=newshref[newsi]; //依次顯示文字對應的連結 if(txti>=hwnewstr.length){ clearInterval(txttimer); //一旦超過要顯示的文字長度，清除對shownew()的周期性調用 clearInterval(newstimer); newsi++; //顯示數組中的下一個 if(newsi>=newstitle.length){ newsi = 0; //當newsi大於資訊標題的數量時，把newsi清零，重新從第一個顯示 } newstimer = setInterval("shownew()",NewsTime); //間隔2000ms後重新調用shownew() txti = 0; return; } clearInterval(txttimer); document.getElementById("Hotnews").href = newslink; document.getElementById("Hotnews").innerHTML = hwnewstr.substring(0,txti+1); //截取字元，從第一個字元到txti+1個字元 txti++; //文字一個個出現 txttimer = setInterval("shownew()",TextTime); } shownew();</script></body></html>
