//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 } }<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>
2.在模板页面引用js.
<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>
