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.
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> |
