网页中添加MSN和QQ等即时通讯的链接？

QQ 很简单,直接到官网(http://imis.qq.com/webpresence/code.shtml)选择相关的样式,复制其代码即可.

MSN相对有点复杂,需用如下代码:

<script type="text/JavaScript">
function msnoperate(action, msn) {
var actionArray = new Array();
actionArray = {
'reghotmail' : 'http://go.discuz.com/?app=msn&linkid=1',
'reglivemail' : 'http://go.discuz.com/?app=msn&linkid=2',
'regliveid' : 'http://go.discuz.com/?app=msn&linkid=3',
'download' : 'http://go.discuz.com/?app=msn&linkid=4',
'add' : 'http://go.discuz.com/?app=msn&linkid=5&msn=' + msn,
'chat' : 'http://go.discuz.com/?app=msn&linkid=6&msn=' + msn
}

if(messengerInstalled()) {
window.open(actionArray[action]);
} else {
window.open('http://go.discuz.com/msn/msn.html','_blank','width=571, height=498');
}
}

function messengerInstalled() {
try {
new ActiveXObject("MSNMessenger.P4QuickLaunch");
return true;
}
catch (e) {
return false;
}
}
</script>

引用:
<a href="#" onclick="msnoperate('chat', 'user@hotmail.com')"><img src="images/default/msnchat.gif" border="0" alt="通过MSN和 user 交谈"></a>

另外,有的不需要以上那么复杂,可以直接用以下代
<a href="msnim:chat?contact=user@hotmail.com" target="blank" > <img src="images/default/msnchat.gif" align="absmiddle" border="0" alt="MSN：通过MSN和 user 交谈" /> </a>
