dev_code's Issues

第九点关于cookie 的写法有缺陷

var setCookie = {
	set: function(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();
	}
}

这种方式在已存在 cookie键值对的情况下，只是新增一组cookie。并没有实现 setCookie 的功能。

建议改进为

/**
 * 设置cookie
 * @param {string} name  键名
 * @param {string} value 键值
 * @param {integer} days cookie周期
 */
function setCookie(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=/";
}
// 获取cookie
function getCookie(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;
}
// 删除cookie
function deleteCookie(name) {
    setCookie(name,"",-1);
}
