织梦模板使用js记录浏览历史并调用

织梦的这两个函数很重要。织梦模板中使用js记录浏览历史并调用历史记录 他直接简化了JS的COOKIE。让他由复杂变的简单了。这两个函数在AJAX里面的。

在include/js/dedeajax2.js里面,

//读写cookie函数

function GetCookie(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));

}

}

return null

}

function SetCookie(c_name,value,expiredays)

{

var exdate = new Date();

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:

function getCookies(ids,title,img){

var saveid = GetCookie(‘id’);

var savetitle = GetCookie(‘products’);

var saveimg = GetCookie(‘images’);

if(saveid != null && savetitle != null && saveimg != null)

{

var saveids = saveid.split(‘,’);

var savetitles = savetitle.split(‘,’);

var saveimgs = saveimg.split(‘,’);

var hasid = 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) { return false; }

else saveid += ‘,’+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.

<script language=”javascript” type=”text/javascript” src=https://www.91084.com/”{dede:global.cfg_cmsurl/}/include/js/dedeajax2.js”></script>

<script language=”javascript” type=”text/javascript”>

getCookies({dede:field.id/},’{dede:field.title/}’,’{dede:field.litpic/}’)

function CheckLogin2(){

var taget_obj = document.getElementByIdx_x_x(‘_userlogin’);

myajax = new DedeAjax(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:

<div class=”Recommend h-394″>

<h1 class=”rec-bg”><span class=”span-rt-3″><a onclick=”destroy_cookie()”>清空</a></span>最近浏览过的文章</h1>

<ul class=”w-223 browse ” id=”viewHistory”>

<script type=”text/javascript”>

function destroy_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>

<script type=”text/javascript”>

var saveid = GetCookie(‘id’);

var savetitle = GetCookie(‘products’);

var saveimg = GetCookie(‘images’);

if(saveid != null && savetitle != null)

{

var saveids = saveid.split(‘,’);

var savetitles = savetitle.split(‘,’);

var saveimgs = saveimg.split(‘,’);

var hasid = false;

saveid = ”;

savetitle = ”;

saveimg = ”;

for(i=saveids.length-1;i>=0;i–)
