将对象的属性和值转换为键值对数组 [英] Convert object's properties and values to array of key value pairs

问题描述

我对 JavaScript 还很陌生，不确定这是否可行，但基本上我想获取一个对象并将其转换为格式的字符串数组；array[0] = 'prop1=value1'

I'm fairly new to JavaScript and am not sure this is possible to do but basically I would like to take an object and convert it into an array of strings in the format; array[0] = 'prop1=value1'

这背后的原因是我让用户将 k=v 对的列表输入到一个表单中，后来它被写成一个 json blob 中的对象.从键值 csl 到 json 对象很简单，现在我需要以另一种方式返回(我已经通过 ajax 调用接收到 JSON 并想要填充一个空白表单).这在 JavaScript 中可行吗?如果没有，请提供合理的解决方法.

The reasoning behind this is that I'm having a user enter a list of k=v pairs into a form, later it's written as an object within a json blob. Going from the key value csl to the json object was simple, now I need to go back the other way (I've received the JSON via an ajax call and want to populate a blank form). Is this possible in JavaScript? If not please offer a reasonable work around.

示例代码；

调试器中的对象；

 Object
        private_key: "private-key"
        public_key: "public-key"

我需要将其转换为;

 "private_key=private-key,public_key=public-key"

基本上我需要这样的东西(伪代码)

Basically I need something like this (pseudo code)

var outputString = '';
foreach (prop in obj)
{
    outputString = outputString + prop.tostring() + '=' + prop.value + ',';
}

推荐答案

您可能正在寻找类似

var obj = {value1: 'prop1', value2: 'prop2', value3: 'prop3'};
var arr = [];
for (var key in obj) {
    if (obj.hasOwnProperty(key)) {
        arr.push(key + '=' + obj[key]);
    }
};
var result = arr.join(',');
alert(result);

请注意，如果您的值是字符串，它将正常工作；如果它们是复杂的对象，那么您需要添加更多代码.

Notice that it will work fine if your values are strings; if they're complex objects then you'll need to add more code.

或者你可以只使用 jQuery.param，它可以做你想做的事，即使是复杂类型(尽管它使用 & 字符作为分隔符，而不是逗号.

Or you can just use jQuery.param, which does what you want, even for complex types (although it uses the & character as the separator, instead of the comma.
