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。
