1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>index方法獲取Jquery對象的數組下標</title> <style type="text/css"> #main{ width:600px; border:1px solid green; margin:auto; padding:10px; } #tbl{ border-collapse:collapse; border-top:1px solid red; border-left:1px solid red; margin:auto; } #tbl td{ width:60px; height:60px; border-collapse:collapse; border-bottom:1px solid red; border-right:1px solid red; } </style> <script src="jquery-1.6.2.min.js" type="text/javascript"></script> <script type="text/javascript"> var oldColor; $(function () { $("#tbl tr").hover( function () { oldColor = $(this).css("backgroundColor"); $(this).css("backgroundColor", "yellow"); }, function () { $(this).css("backgroundColor", oldColor); }); $("#tbl tr").click(function () { alert($("#tbl tr").index($(this))); //獲取元素下標 }); }); </script> </head> <body> <div id="main"> <table id="tbl"> <tr> <td>1</td><td>1</td><td>1</td> </tr> <tr> <td class="tdClass">2</td><td>2</td><td>2</td> </tr> <tr> <td>3</td><td>3</td><td>3</td> </tr> <tr> <td>4</td><td>4</td><td class="tdClass">4</td> </tr> <tr> <td>5</td><td>5</td><td>5</td> </tr> <tr> <td>6</td><td>6</td><td class="tdClass">6</td> </tr> </table> </div> </body> </html>希望本文所述對大家的jQuery程序設計有所幫助。
