织梦用js记录浏览历史，并且调用历史记录

//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="{wmd:global.cfg_cmsurl/}/include/js/dedeajax2.js"></script>

<scriptlanguage="javascript"type="text/javascript">

getCookies({wmd:field.id/},'{wmd:field.title/}','{wmd:field.litpic/}')

functionCheckLogin2(){

vartaget_obj=document.getElementByIdx_x_x('_userlogin');

myajax=newDedeAjax(taget_obj,false,false,'','','');

myajax.SendGet2("{wmd: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>
