frame 属性可设置或返回表格的外部边框。
tableObject.frame=void|above|below|hsides|vsides|lhs|rhs|box|border
下面的例子设置了表格的两种不同的边框:
<html> <head> <script type="text/javascript"> function aboveFrames() {document.getElementById('myTable').frame="above"
} function belowFrames() {document.getElementById('myTable').frame="below"
} </script> </head> <body> <table id="myTable"> <tr> <td>100</td> <td>200</td> </tr> <tr> <td>300</td> <td>400</td> </tr> </table> <br /> <input type="button" onclick="aboveFrames()" value="Show above frames"> <input type="button" onclick="belowFrames()" value="Show below frames"> </body> </html>
