//读写cookie函数
functionGetCookie(c_name)
{
if(document.cookie.length>0)
{
c_start=document.cookie.indexOf(c_name+"=")
if(c_start!=-1)
{
c_start=c_start+c_name.length+1;
c_end=document.cookie.indexOf(";",c_start);
if(c_end==-1)

c_end=document.cookie.length;
}
return(document.cookie.substring(c_start,c_end));
}
}
returnnull
}
functionSetCookie(c_name,value,expiredays)
{
varexdate=newDate();
exdate.setDate(exdate.getDate()+expiredays);
document.cookie=c_name+"="+escape(value)+((expiredays==null)?"":";expires="+exdate.toGMTString());//使设置的有效时间正确。增加toGMTString()
}
-->
增加一个函数。
如下：
functiongetCookies(ids,title,img){
varsaveid=GetCookie('id');
varsavetitle=GetCookie('products');
varsaveimg=GetCookie('images');
if(saveid!=null&&savetitle!=null&&saveimg!=null)
{
varsaveids=saveid.split(',');
varsavetitles=savetitle.split(',');
varsaveimgs=saveimg.split(',');
varhasid=false;
saveid='';
savetitle='';
saveimg='';
j=1;
for(i=saveids.length-1;i>=0;i--)
{
if(saveids[i]==ids&&hasid)continue;
else{
if(saveids[i]==ids&&!hasid)hasid=true;
saveid+=(saveid==''?saveids[i]:','+saveids[i]);
savetitle+=(savetitle==''?savetitles[i]:','+savetitles[i]);
saveimg+=(saveimg==''?saveimgs[i]:','+saveimgs[i]);
j++;
if(j==10&&hasid)break;
if(j==9&&!hasid)break;
}
}
if(hasid){returnfalse;}
elsesaveid+=','+ids;
savetitle+=','+title;
saveimg+=','+img;
SetCookie('id',saveid,1);
SetCookie('products',savetitle,1);
SetCookie('images',saveimg,1);
}
else
{
SetCookie('id',ids,1); //这个是ID。用来做链接用的
SetCookie('products',title,1); //这个是标题，用来显示在页面的
SetCookie('images',img,1); //这个是图片
}
}
2.在页面引用js.
<scriptlanguage="javascript"type="text/javascript"src="{dede:global.cfg_cmsurl/}/include/js/dedeajax2.js"></script>
<scriptlanguage="javascript"type="text/javascript">
getCookies({dede:field.id/},'{dede:field.title/}','{dede:field.litpic/}')
functionCheckLogin2(){
vartaget_obj=document.getElementByIdx_x_x('_userlogin');
myajax=newDedeAjax(taget_obj,false,false,'','','');
myajax.SendGet2("{dede:global.cfg_cmspath/}/member/ajax_loginsta2.php");
DedeXHTTP=null;
}
</script>
调用历史记录的代码：
<divclass="Recommendh-394">
<h1class="rec-bg"><spanclass="span-rt-3"><aonclick="destroy_cookie()">清空</a></span>最近浏览过的课程</h1>
<ulclass="w-223browse"id="viewHistory">
<scripttype="text/javascript">
functiondestroy_cookie(){
SetCookie('id','',1);
SetCookie('products','',1);
SetCookie('images','',1);
document.getElementByIdx_x_x('viewHistory').innerHTML="";
window.alert('你已成功清除浏览历史记录！');
}
</script>
<scripttype="text/javascript">
varsaveid=GetCookie('id');
varsavetitle=GetCookie('products');
varsaveimg=GetCookie('images');
if(saveid!=null&&savetitle!=null)
{
varsaveids=saveid.split(',');
varsavetitles=savetitle.split(',');
varsaveimgs=saveimg.split(',');
varhasid=false;
saveid='';
savetitle='';
saveimg='';
for(i=saveids.length-1;i>=0;i--)
{
document.write("<li>"+"<divclass='w-53'><ahref="/plus/view.php?aid="+saveids[i]+""title=""+savetitles[i]+""><imgsrc='"+saveimgs[i]+"'width='52'height='51'/></a></div><pclass='w-53-rt'><ahref="/plus/view.php?aid="+saveids[i]+""title=""+savetitles[i]+"">"+savetitles[i]+"</a></p></li>");
}
}
</script>
</ul>
</div>
