本文讲述了JS实现鼠标悬停切换图片,显示天气预报,利用焦点实现选择网站的实例代码,分享给大家供大家参考,具体如下:
鼠标悬停切换图片:
<html> <head> <script type="text/javascript"> function mouseOver() { document.getElementById('b1').src ="diaochan.jpg" } function mouseOut() { document.getElementById('b1').src ="noimage.gif" } </script> </head> <body> <a href="#" onmouseover="mouseOver()" onmouseout="mouseOut()"> <img alt="Visit W3School!" src="noimage.gif" id="b1" onmouseover="alert('你的鼠标在图片上!')")/> </a> </body> </html>
js显示天气预报:
<html> <head><title></title> <script type="text/javascript"> </script> </head> <body > <div> <iframe src="http://m.weather.com.cn/m/pn11/weather.htm" width="480" height="70" frameborder="1"></iframe> </div> </body> </html>
js利用焦点实现选择网站:
<html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script type="text/javascript"> var i = 1; var focusid; function defau() { document.getElementById('1').focus(); focusid=1; } function showtable() { var id = i + 1; document.getElementById(id).focus(); focusid=id; i++; if (i == 4) { i = 0; } } function openhref() { var href = document.getElementById(focusid).href; document.location = href; } </script> </head> <body onload="defau()"> <a href="http://www.baidu.com/" id="1">百度</a> <a href="http://www.google.com.hk/" id="2">谷歌</a> <a href="http://www.youku.com/" id="3">优酷</a> <a href="http://www.tudou.com/" id="4">土豆</a> <input id="Button1" type="button" value="选择" onclick="showtable()" /><br /> <input id="Button2" type="button" value="进入" onclick="openhref()" /> </body> </html>
