javascript,鼠标滑动,评分控件本文实例讲述了javascript鼠标滑动评分控件。分享给大家供大家参考。具体实现方法如下： <html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>javascript鼠标滑动控件</title><script type="text/javascript">function ArrayIndexof(arr, inElement) { for (var i = 0; i < arr.length; i++) { if (arr[i] == inElement) { return i; } } return -1;}function GetTDS() { var tbl = document.getElementById("tblMain"); var tds = tbl.getElementsByTagName("td"); return tds; }function iniEvent() { var tds = GetTDS(); for (var i = 0; i < tds.length; i++) { td = tds[i]; td.onmouseover = TdOnMouseOver; } var tbl = document.getElementById("tblMain"); tbl.onmouseout = TableMouseOut;}function SetRating(tdTmp) { var tds = GetTDS(); var index = ArrayIndexof(tds, tdTmp); for (var i = 0; i <= index; i++) { td = tds[i]; td.innerHTML = "★"; } for (var i = index + 1; i < tds.length; i++) { td = tds[i]; td.innerHTML = "☆"; }}function TdOnMouseOver() { SetRating(this);}//鼠标离开表格后自动清除function TableMouseOut() { var tds = GetTDS(); for (var i = 0; i < tds.length; i++) { td = tds[i]; td.innerHTML = "☆"; }}</script></head><body onload="iniEvent()"><table id="tblMain" border="1"><tr> <td>☆</td> <td>☆</td> <td>☆</td> <td>☆</td> <td>☆</td></tr></table></body></html>希望本文所述对大家的javascript程序设计有所帮助。
