[英]how to get value from cookie in javascript
我需要的:
我需要使用cookie中的用户和evnt_id。
document.cookie
字串:
" country=India; countryCode=IN; __gads=ID=369fde524de77341:T=1417077062:S=ALNI_MakhfG3fYeRIwt9Uw4xSUE8m-2hHw; fbm_172404889604820=base_domain=.10times.com; PHPSESSID=4e467l46efdmvc9vktknod85b2; evnt_id=9; industry=74; evnt_name=India International Trade Fair; evnt_url=iitf; km_ai=jE0JIU3hamljHh0DrWRC%2FR50QNI%3D; km_lv=x; __zlcmid=SAeGECzmK8Nrve; user_flag=2; user=13530767; _ga=GA1.2.1767513107.1417003918; linkedin_oauth_ro57ogahnixy_crc=null; km_uq=; kvcd=1418207265523; _ga=GA1.3.342868374.1416999745; id=13530767; email=afeef1915%40yahoo.com; name=Mohd+Afeef; image_flag=http%3A%2F%2Fgraph.facebook.com%2F100001729894039%2Fpicture".
我需要拿
我尝试过的代码:
function setCookie(key, value) {
var expires = new Date();
expires.setTime(expires.getTime() + 31536000000); //1 year
document.cookie = key + '=' + value + ';expires=' + expires.toUTCString();
}
function getCookie(key) {
var keyValue = document.cookie.match('(^|;) ?' + key + '=([^;]*)(;|$)');
return keyValue ? keyValue[2] : null;
}
setCookie('evnt_id','evnt_id');
alert(getCookie('evnt_id'));
这个问题以前已经解决过。 不要重新发明轮子:)
我建议您阅读Cookie: http : //www.quirksmode.org/js/cookies.html
下面的代码来自该文章。
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
console.log(readCookie('evnt_id')); //9
console.log(readCookie('user')); //13530767
