Convert object's properties and values to array of key value pairs
introspection, javascript, reflection
Solution
You're probably looking for something along the lines of
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);
Notice that it will work fine if your values are strings; if they're complex objects then you'll need to add more code.
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.
Problem
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'` 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. Sample code; Object in debugger; ``` Object private_key: "private-key" public_key: "public-key" ``` I need to convert that to; ``` "private_key=private-key,public_key=public-key" ``` Basically I need something like this (pseudo code) ``` var outputString = ''; foreach (prop in obj) { outputString = outputString + prop.tostring() + '=' + prop.value + ','; } ```
