把哈希放在JavaScript cookie

Question

我想在JavaScript cookie中包含一個哈希，因爲我有一個事情要記住的清單...任何人都可以電話如何設置cookie和方法來檢索它？

Answer 1

您可以在JavaScript中設置cookie的是這樣的：

document.cookie = 'somekey=somevalue; expires=Thu, 2 Aug 2011 21:17:11 UTC; path=/' 

代碼來創建，讀取以JavaScript編寫&擦除餅乾（由Quirksmode）：

function createCookie(name,value,days) { 
    if (days) { 
     var date = new Date(); 
     date.setTime(date.getTime()+(days*24*60*60*1000)); 
     var expires = "; expires="+date.toGMTString(); 
    } 
    else var expires = ""; 
    document.cookie = name+"="+value+expires+"; path=/"; 
} 

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; 
} 

function eraseCookie(name) { 
    createCookie(name,"",-1); 
}
