浅谈部门前台框架中的几个方法<二>

   下面要说的这几个方法,很少有人用到,或者说少有人知道.所以,我看到很多js文件里开发者们大把大把的重复造轮子,这应该是框架维护人员的责任,一直以来,没有形成个详细的api文档.但也说明,开发人员之间缺少对框架的关注,或者说,交流不够.

formatNumber2: function (value){
    return Math.round(value * 100) / 100;
},
//数值精确到<digit>小数位
formatNum: function (value, digit){
    if (digit == undefined) return Math.round(value * 100) / 100;
    else{
        if (digit == 0){
            return Math.round(value);
        }
        else{
            var tmp = Math.pow(10, digit);
            return Math.round(value * tmp) / tmp;
        }
    }
},
formatWZ: function (value){
    return "" + value + "万支";
},
//数值加上百分号
formatPercent: function (value){
    return value + "%";
},
formatPercent2: function (value){
    return Math.round(value * 10000) / 100 + "%";
},
//字期值<string>转化为YYYY-MM-dd格式
formatDate: function (v){
    if (v == undefined) v = "";
    if (v.indexOf('-') == - 1) return v.substr(0, 4) + "-" + v.substr(4, 2) + "-" + v.substr(6, 2);
    else return v;
},
//字期值<string>转化为YYYY-MM-DD hh:mm:ss格式
toFullDate: function (v){
    return v.substr(0, 4) + "-" + v.substr(4, 2) + "-"//月
    + v.substr(6, 2) + " "//日
    + v.substr(8, 2) + ":"//时
    + v.substr(10, 2) + ":"//分
    + v.substr(12, 2);//秒
},
toDate: function (v){
    var flag = (v.indexOf('-') == - 1) ? true : false;
    var year = v.substr(0, 4);
    var month = (flag) ? v.substr(4, 2) : v.substr(5, 2);
    var day = (flag) ? v.substr(6, 2) : v.substr(8, 2);
    month = parseInt(month) - 1;
    return new Date(year, month, day);
},
toTime: function (value){
    if (value == "") return "";
    if (value.length & gt; 6 & amp; & amp; value.indexOf(":") == - 1) value = value.left(6);
    if (value.indexOf(":") == - 1 & amp; & amp; value.length == 6){
        if ( ! Sail.isTime(value)) return "";
        var vs = "" + value;
        return vs.substr(0, 2) + ":" + vs.substr(2, 2) + ":" + vs.substr(4, 2);
    }
    var vs = value.split(":");
    if (vs.length == 1){
        var vback = value;
        vs = [];
        
        var h = parseInt(vback.left(2), 10) || 0;
        vs.push((h & gt; 23) ? vback.left(1) : "" + h);
        vback = ((h & gt; 23) ? vback.right(vback.length - 1) : vback.right(vback.length - 2));
        
        var h = parseInt(vback.left(2), 10) || 0;
        vs.push((h & gt; 59) ? vback.left(1) : "" + h);
        vback = ((h & gt; 59) ? vback.right(vback.length - 1) : vback.right(vback.length - 2));
        
        vs.push((parseInt(vback, 10) & gt; 59) ? "0" : vback);
    }
    for (var i = 0; i & lt; vs.length; i++){
        vs[i] = (vs[i] == "") ? "00" : vs[i];
        
        if (vs[i].length == 1 & amp; & amp; parseInt(vs[i], 10) & lt; 10 & amp; & amp; parseInt(vs[i], 10) != 0){
            vs[i] = "0" + vs[i];
        }
        if (vs[i] == "0") vs[i] = "00";
    }
    return vs.join(":");
},
num2String: function (num, format){
    var str = "" + num;
    var formatLen = format.length;
    if (str.length & lt; formatLen){
        var len = formatLen - str.length;
        for (var i = 0; i & lt; len; i++) str = "0" + str;
    }
    return str;
}

  其中我注释的函数是项目中实际用得比较多的,但大家不知道,所以就重复的造轮子.很简单,比如我要转换一个字符串为日期,就可以这样写.Sail.toFullDate(argv)

  如果不知道,也不去关注.那就悲剧了,截图为证:
