1.首先介绍下js操作cookie
//写 function setCookie(name,value) { var Days = 30; var exp = new Date(); exp.setTime(exp.getTime() + Days*24*60*60*1000); document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString(); } // 读 function getCookie(name) { var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)"); if(arr=document.cookie.match(reg)) return unescape(arr[2]); else return null; } //删 function delCookie(name) { var exp = new Date(); exp.setTime(exp.getTime() - 1); var cval=getCookie(name); if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString(); }
可以在某个页面利用上面代码写入cookie
之后再调用迅雷。
2.调用迅雷
