本文实例讲述了JavaScript动态修改背景颜色的方法。分享给大家供大家参考。具体如下：
<html> <head> <title>Background Color Changer</title> <script language = JavaScript> <!-- function BG_yellow() { document.bgColor = 0xFFFF00 } function BG_thistle() { document.bgColor = 0xD8BFD8 } function BG_plum() { document.bgColor = 0xDDA0DD } function BG_red() { document.bgColor = 0xFF0000 } //--> </script> </head> <body > <center> <form> <font face="comic sans ms"> <br> <h1> Set the background color </h1> <br> <input type = button value = "Make background Yellow " onclick = "BG_yellow()"> <br> <br> <input type = button value = "Make background Thistle" onclick = "BG_thistle()"> <br> <br> <input type = button value = "Make background Plum" onclick = "BG_plum()"> <br> <br> <input type = button value = "Make background Red" onclick = "BG_red()"> </font> </form> </center> </body> </html>
希望本文所述对大家的javascript程序设计有所帮助。
