用于json post的JavaScript中的条件对象

I have a function named update that takes some options and post to my php using $.post:

我有一个名为update的函数，它接受一些选项并使用$ .post发布到我的php：

 function update(options){
   $.post('update.php',{update: options}, function(data, textStatus, jqXHR){
     // debug stuff from php
   });
 }

I call my function as follows:

我把我的功能称为如下：

 update({'id': id, 'option': val});

What I would like to know is how I can make a conditional inside the options? For example:

我想知道的是我如何在选项中制定条件？例如：

 var option = $(this).attr('class') == 'check' ? 'check' : 'ok'; // assuming option is ok

 update({'id': id, 'ok': val}); // instead of option

 update({'id': id, option: val}); // i want to have the conditional

You can access Javascript objects in the same way that you access arrays. This syntax supports dynamic property names/keys.

您可以像访问数组一样访问Javascript对象。此语法支持动态属性名称/键。

options[variable] = 'value';

Example:

例：

var x = 'customProperty'
,   y = {}
;

y.x = 12; //y.x = 12
y[x] = 11; //y.customProperty = 11... same as y['customProperty'] = 11

Essentially you set your object as such:

基本上你设置你的对象：

var x = {};

Then assign the exact property you want

然后分配您想要的确切属性

var prop_name = $(this).attr('class') == 'check' ? 'check' : 'ok';
x[prop_name] = YOUR_VALUE;
