  • jQuery 如何存储,获取和删除 Cookies

    jQuery.cookie = function(name, value, options) {
    	if (typeof value != 'undefined') {
    		options = options || {};
    		if (value === null) {
    			value = '';
    			options = $.extend({}, options);
    			options.expires = -1;
    		}
    		var expires = '';
    		if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) {
    			var date;
    			if (typeof options.expires == 'number') {
    				date = new Date();
    				date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));
    			} else {
    				date = options.expires;
    			}
    			expires = '; expires=' + date.toUTCString();
    		}
    		var path = options.path ? '; path=' + (options.path) : '';
    		var domain = options.domain ? '; domain=' + (options.domain) : '';
    		var secure = options.secure ? '; secure' : '';
    		document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');
    		} else {
    			var cookieValue = null;
    			if (document.cookie && document.cookie != '') {
    			var cookies = document.cookie.split(';');
    			for (var i = 0; i < cookies.length; i++) {
    				var cookie = jQuery.trim(cookies[i]);
    				if (cookie.substring(0, name.length + 1) == (name + '=')) {
    					cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
    					break;
    				}
    			}
    		}
    		return cookieValue;
    	}
    };

    然后通过下面方法使用:

    $(document).ready(function() {
    	$('#write_cokies').click(function(){
    		$.cookie('name', 'test',{expires: 7});				  
    	});
    	$('#read_ookies').click(function(){
    		var test = $.cookie('name');
    		alert (test);
    	});
    	$('#delete_cookies').click(function(){
    		$.cookie('name', null);							  
    	});
    });
