js format方法的SRC
String.prototype.format = function(args) { if (arguments.length>0) { var result = this; if (arguments.length == 1 && typeof (args) == "object") { for (var key in args) { var reg=new RegExp ("({"+key+"})","g"); result = result.replace(reg, args[key]); } } else { for (var i = 0; i < arguments.length; i++) { if(arguments[i]==undefined) { return ""; } else { var reg=new RegExp ("({["+i+"]})","g"); result = result.replace(reg, arguments[i]); } } } return result; } else { return this; } }

?js 取得select 的选中的text

：

var rangeChange = function (obj) {
?alert(_NAME_ARRAY);
?// 把没选的加入array
//?alert(obj.options[obj.selectedIndex].text);
}
