js之：部分常用方法封装

获取引用js的绝对路径：

var getPath = function(){
    var jsPath = document.currentScript ? document.currentScript.src : function(){
      var js = document.scripts
      ,last = js.length - 1
      ,src;
      for(var i = last; i > 0; i--){
        if(js[i].readyState === 'interactive'){
          src = js[i].src;
          break;
        }
      }
      return src || js[last].src;
    }();
    return jsPath.substring(0, jsPath.lastIndexOf('/') + 1);
  }()

console.log(decodeURIComponent)

获取节点的style属性值：

var getStyle = function(node, name){
    var style = node.currentStyle ? node.currentStyle : win.getComputedStyle(node, null);
    return style[style.getPropertyValue ? 'getPropertyValue' : 'getAttribute'](name);
  };

 本地内存相关

// 本地存储相关 
    localStorage: {
      getItem: function(key) {
        return JSON.parse(localStorage.getItem(key));
      },
      setItem: function(key, data) {
        var d = (typeof data === 'object' || typeof data === 'array') ?
          JSON.stringify(data) : data;
        localStorage.setItem(key, d);
      },
      removeItem: function(key) {
        localStorage.removeItem(key);
      },
      clear: function() {
        localStorage.clear();
      }
    }

cookie相关

setCookie: function(name, value, expiredays) {
            var exdate = new Date();
            exdate.setDate(exdate.getDate() + (expiredays || 30));
            document.cookie = name + "=" + escape(value) + ";path=/;expires=" + exdate.toGMTString();
        }

getCookie: function(name) {
            var arr,
                reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)");
            if (arr = document.cookie.match(reg)) {
                return unescape(arr[2]);
            } else {
                return null;
            }
        }

delCookie: function(name) {
            this.setCookie(name, "", -1); 
        },

日期相关：

//日期
Date.prototype.pattern = function(fmt) {
    var o = {
        "M+": this.getMonth() + 1, //月份           
        "d+": this.getDate(), //日           
        "h+": this.getHours() % 12 == 0 ? 12 : this.getHours() % 12, //小时           
        "H+": this.getHours(), //小时           
        "m+": this.getMinutes(), //分           
        "s+": this.getSeconds(), //秒           
        "q+": Math.floor((this.getMonth() + 3) / 3), //季度           
        "S": this.getMilliseconds() //毫秒           
    };
    var week = {
        "0": "/u65e5",
        "1": "/u4e00",
        "2": "/u4e8c",
        "3": "/u4e09",
        "4": "/u56db",
        "5": "/u4e94",
        "6": "/u516d"
    };
    if (/(y+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    }
    if (/(E+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, ((RegExp.$1.length > 1) ? (RegExp.$1.length > 2 ? "/u661f/u671f" : "/u5468") : "") + week[this.getDay() + ""]);
    }
    for (var k in o) {
        if (new RegExp("(" + k + ")").test(fmt)) {
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
        }
    }
    return fmt;
};

// 时间转10位时间戳
        get10Time: function(time) {
            var date = time ? new Date(time) : new Date();
            return Math.round(date.getTime() / 1000);
        },
        // 10位时间戳转时间
        timeToStr: function(time, fmt) {
            return new Date(time * 1000).pattern(fmt || 'yyyy-MM-dd');
        },

//秒数转时分秒
        formatSeconds: function(second) {
            var theTime = parseInt(second); // 秒 
            var theTime1 = 0; // 分 
            var theTime2 = 0; // 小时 
            // alert(theTime); 
            if (theTime > 60) {
                theTime1 = parseInt(theTime / 60);
                theTime = parseInt(theTime % 60);
                // alert(theTime1+"-"+theTime); 
                if (theTime1 > 60) {
                    theTime2 = parseInt(theTime1 / 60);
                    theTime1 = parseInt(theTime1 % 60);
                }

            var result = "" + parseInt(theTime) + "秒";
            if (theTime1 > 0) {
                result = "" + parseInt(theTime1) + "分" + result;
            }
            if (theTime2 > 0) {
                result = "" + parseInt(theTime2) + "小时" + result;
            }
            return result;
        },

url相关：

// 查询当前url中的参数的值
        getQueryString: function(name, url) {
            if (url === undefined) {
                url = $$.getUrl();
            }
            if (url.indexOf('?') == -1) {
                return undefined;
            }
            var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
            var q = url.split("?");
            var r = q[1].match(reg);
            if (r != null) return unescape(r[2]);
        },
        // 当前url
        getUrl: function() {
            return location.href;
        },
