[英]Object-Oriented JavaScript Converter
So I am working in a converter application powered by JavaScript, and right now I am trying to create a huge object with all the measures. 因此,我正在使用JavaScript驱动的转换器应用程序中工作,现在我正在尝试使用所有措施来创建一个巨大的对象。 But whenever I debug it, it's saying things like:
但是,每当我调试它时,它都会说类似以下内容:
Expected ';' and instead saw '.' (var units.length = {};) Expected '.' at column 1, not column 10 (var units.length = {};) Unexpected '.' (var units.length = {};) etc.
It's been a long time since I coded in JS, so I'm having some confusion with it, would appreciate any help, here's the code: 自从我用JS编码以来已经有很长时间了,所以我对此有些困惑,不胜感激,请看下面的代码:
var units = {};
var units.length = {};
var units.time = {};
var units.mass = {};
var units.temperature = {};
//Starting with Length
units.length.meter = 1;
units.length.meters = 1;
units.length.inch = 0.0254;
units.length.inches = 0.0254;
units.length.foot = 0.3048;
units.length.feet = 0.3048;
units.length.yard = 0.9144;
units.length.yards = 0.9144;
units.length.mile = 1609.344;
units.length.miles = 1609.344;
...
Only use var
to declare variables, not to create properties of an existing object: 仅使用
var
声明变量,而不使用创建现有对象的属性:
var units = {};
units.length = {};
units.time = {};
units.mass = {};
units.temperature = {};
//Starting with Length
units.length.meter = 1;
units.length.meters = 1;
units.length.inch = 0.0254;
units.length.inches = 0.0254;
units.length.foot = 0.3048;
units.length.feet = 0.3048;
units.length.yard = 0.9144;
units.length.yards = 0.9144;
units.length.mile = 1609.344;
units.length.miles = 1609.344;
Also consider 还考虑
var units = {
length: {
meter: 1,
meters: 1,
inch: 0.0254,
inches: 0.0254,
foot: 0.3048,
feet: 0.3048,
yard: 0.9144,
yards: 0.9144,
mile: 1609.344,
miles: 1609.344
},
time: {},
mass: {},
temperature: {}
};
No var
before attributes, only variables. 属性前没有
var
,只有变量。
var units = {
length: {},
time: {},
mass: {},
temperature : {}
};
NB: length is reserved to array/string length, you should avoid to name an attribute like that. 注意:length保留为数组/字符串的长度,应避免这样命名属性。 And you should use an extend method to avoid to repeat
units
and units.length
. 并且您应该使用扩展方法来避免重复
units
和units.length
。
var units = {
length: {
meter: 1,
meters: 1,
inch: 0.0254,
inches: 0.0254 // ...
},
time: {},
mass: {},
temperature : {}
};
