csdn的前端代码好像不太规范
<script type="text/javascript">
function getCookie( name ) {
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if( arr != null )
{
return decodeURIComponent( arr[ 2 ] );
}
return null;
}
function csdnShowSpaceNotify( data ) {
document.getElementById("header_notice_num").innerHTML = parseInt( data.n ) > 0 ? data.n : 0;
if( parseInt( data.l ) > 0 )
{
document.getElementById("header_letter_num").innerHTML = "（"+data.l+"）";
}
}
window.csdnShowSpaceNotify = csdnShowSpaceNotify;
var userName = getCookie( "UserNick" );
if ( userName && userName != "Guest" )
{
document.getElementById("login").innerHTML = "";
document.getElementById("showinfo").innerHTML = "<em>"+ userName + "</em><a href="http://notify.csdn.net/dashboard" class="notice_num" id="header_notice_num"></a>我的：<a href="http://my.csdn.net/my/letter">收件箱<span id="header_letter_num"></span></a><a href='http://download.csdn.net/my' class='red'>资源</a> <a href='http://write.blog.csdn.net/' class='red'>博客</a> <a href='http://my.csdn.net/'>空间</a> <a href='https://passport.csdn.net/account/profile'>设置</a>| <a href='https://passport.csdn.net/help/faq'>帮助</a>| <a href='http://passport.csdn.net/account/logout'>退出</a><input type='text' name='passwordtwo' class='search' value='搜索' onfocus="if(this.value=='搜索') this.value='';this.style.color='#333'; return true;" onblur="if(this.value=='') this.value='搜索'; this.style.color='#999'; return true;" id='srch1' />";
}
if ( userName && userName != "Guest" )
{
( function() {
var ca = document.createElement( 'script' );
ca.type = 'text/javascript';
ca.async = true;
ca.src = 'http://my.csdn.net/index.php/service/notifications/getnl?jsonpcallback=csdnShowSpaceNotify';
