js对象内怎么复制属性
比如有对象

JScript code

var obj = {    companyname:function(option){        var format    = validateRules.isCompanyname(option.value);        var length    = validateRules.betweenLength(option.value,1,50);        var opt        = option;        if(!format || !length){            if(!format) opt.errInfo = option.prompts.error.badFormat;            if(!length) opt.errInfo = option.prompts.error.badLength;            validateFunction.errorfunc(opt);        }else{            validateFunction.succefunc(option);        }            }//companyname end    ,companyaddr:function(option){        var format    = validateRules.isCompanyname(option.value);        var length    = validateRules.betweenLength(option.value,1,50);        var opt        = option;        if(!format || !length){            if(!format) opt.errInfo = option.prompts.error.badFormat;            if(!length) opt.errInfo = option.prompts.error.badLength;            validateFunction.errorfunc(opt);        }else{            validateFunction.succefunc(option);        }    }}

因为companyname和companyaddr属性是一样的函数，我想简写为

JScript code

var obj = {    companyname:function(option){        var format    = validateRules.isCompanyname(option.value);        var length    = validateRules.betweenLength(option.value,1,50);        var opt        = option;        if(!format || !length){            if(!format) opt.errInfo = option.prompts.error.badFormat;            if(!length) opt.errInfo = option.prompts.error.badLength;            validateFunction.errorfunc(opt);        }else{            validateFunction.succefunc(option);        }            }//companyname end    ,companyaddr:this.companyname}

改了后提示object is not a function，不能正确引用函数

在内部写是不行的，因为obj是一个数组对象，这样写是可以的：

var obj = {
companyname:function(option){
var format = validateRules.isCompanyname(option.value);
var length = validateRules.betweenLength(option.value,1,50);
var opt = option;
if(!format || !length){
if(!format) opt.errInfo = option.prompts.error.badFormat;
if(!length) opt.errInfo = option.prompts.error.badLength;
validateFunction.errorfunc(opt);
}else{
validateFunction.succefunc(option);
}
}//companyname end
,companyaddr:function(option){}
}
obj.companyaddr = obj.companyname;

JScript code

var obj = {    companyname:function(option){        var format    = validateRules.isCompanyname(option.value);        var length    = validateRules.betweenLength(option.value,1,50);        var opt        = option;        if(!format || !length){            if(!format) opt.errInfo = option.prompts.error.badFormat;            if(!length) opt.errInfo = option.prompts.error.badLength;            validateFunction.errorfunc(opt);        }else{            validateFunction.succefunc(option);        }            }//companyname end    ,companyaddr:obj.companyname}
