如何使用jQuery創建Cookie？

Question

如何爲此腳本設置Cookie？

<script type="text/javascript"> 
$(document).ready(function(){ 

    $("a.switch_thumb").toggle(function(){ 
     $(this).addClass("swap"); 
     $("ul.display").fadeOut("fast", function() { 
     $(this).fadeIn("fast").addClass("thumb_view"); 
     }); 
     }, function() { 
     $(this).removeClass("swap"); 
     $("ul.display").fadeOut("fast", function() { 
     $(this).fadeIn("fast").removeClass("thumb_view"); 
     }); 
    }); 

}); 
</script>

你不需要這個jQuery（雖然有幾個$.cookie插件）。您可以使用three cross-browser functions found on 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); 
}
