一些常用的JavaScript函數

複製代碼 代碼如下:

var YX = {

//得到JS內置數據類型的.類型,返回值包括[Date,RegExp,Number,String,Array,Boolean,Function,null,undefined,Object]

getType : function(obj){

return obj == null ? obj + "" : (obj)e(8,-1);

}

//創建一個簡單的類

,createClass : function(){

return function(){

y(this,arguments);

};

}

//格式化字符串,at("{0},{1},haha",["hello","world"])

,format : function(str,params){

var reg = /{(d+)}/g;

return ace(reg,function(match,val){

return params[~~val];

});

}

//格式化字符串,at2("數學={數學},語文={語文},haha",{"數學":100,"語文":99})

,format2 : function(str,params){

var reg = /{([^{}]+)}/g;

return ace(reg,function(match,val){

return params[val];

});

}

//格式化時間,at3(new Date,"yy-mm-dd H:M:S")

,format3 : function(date,patten){

var y = ullYear(),mon = onth() + 1,d = ate(),h = ours(),min = inutes(),s = econds()

,zero = function(o){return ("0"+o)e(-2)}

,matchs = {"yy":y,"y":(y+"")e(-2),"mm":zero(mon),"m":mon,"dd":zero(d),"d":d,"HH":zero(h),"H":h,"MM":zero(min),"M":min,"SS":zero(s),"S":s};

return ace(/yy|y|mm|m|dd|d|HH|H|MM|M|SS|S/g,function(match){

return matchs[match];

});

}

//數組去重,ue([1,1,"1",,]

,unique : function(arr){

var kv = {},len = th,rs = [],t;

for(;len--;){

t = arr[len];

(kv[t]==undefined || kv[t]!==t) && (kv[t]=t,(t));

}

return rs;

}

};
