javascript : create objects dynamically

Question

Ok. I want to create a JSON array dynamically. Case is:

Lets say, I have array:

var arrayCompanyUsers = ["dealers", "builders"];

From the above array, I want to generate another array as below:

[
 "dealers" : {
 "RequestQuote" : false,
 "PlaceOrder" : false,
 },
 "builder" : {
 "RequestQuote" : false,
 "PlaceOrder" : false,
 }
]

Two questions:

1. how to generate resultant array ?
2. can i access the properties as: dealers.RequestQuote ?

• thefourtheye: You mean, you want an Object from that array?
• Rakesh_Kumar: [ "dealers" : { "RequestQuote" : false, "PlaceOrder" : false, }, "builder" : { "RequestQuote" : false, "PlaceOrder" : false, } ] would not be a array.Array does not have key-value pair. You probably want to have Array of Objects like [ {"dealers" : { "RequestQuote" : false, "PlaceOrder" : false, }}, {"builder" : { "RequestQuote" : false, "PlaceOrder" : false, }} ]
• Chintan Soni: Yes ofcourse. But my resultant array will contain objects whose names will be assigned from arrayCompanyUsers
• Chintan Soni: All of you were right. Thanks for you all. You spent time to answer me. Collectively, I have upvoted all of you as you were right.

Answer 1

You can do this with the following snipped:

var arrayCompanyUsers = ['dealers', 'builders'];
var target = {};
for (var i = 0; i < arrayCompanyUsers.length; i++){
 var user = arrayCompanyUsers[i];
 target[user] = {
 'RequestQuote' : false,
 'PlaceOrder' : false,
 };
}
console.log(target);

And yes, you should be able to access the properties with dealers.RequestQuote

Answer 2

You could use Array.prototype.map to create an array of objects:

var output = arrayCompanyUsers.map(function(key) {
 var record = {};
 record[key] = {
 RequestQuote : false,
 PlaceOrder : false,
 }
 record data;
})

To get RequestQuote for the "dealers" record:

function getValue(records, name, value) {
 var matches = records.filter(function(record) {
 return record[name] !== undefined;
 })
 if(matches.length > 0) {
 return matches[0][name][value];
 }
}
console.log(getValue(output, 'dealers', 'RequestQuote'));
// -> false

As an aside, your data would be easier to work with if you used the format:

{
 name: "dealers",
 properties: {
 RequestQuote : false,
 PlaceOrder : false,
 }
}

Answer 3

see this : http://jsfiddle.net/zL5x6xxm/3/

 var arrayCompanyUsers = ["dealers", "builders"];
var result=[];
for(i=0;i<arrayCompanyUsers.length;i++)
{var x=arrayCompanyUsers[i]
 result.push('{'+ x+':{ "RequestQuote" : false, "PlaceOrder" : false, }}'); 
}
console.log(result);

• Chintan Soni: When I tried your solution with some modifiction, I got [{"x":{"RequestQuote":false,"PlaceOrder":false}},{"x":{"RequestQuote":false,"PlaceOrder":false}}]
• Chintan Soni: I did console.log(JSON.stringify(result)); to see the output
• Naeem Shaikh: @ChintanSoni create a fiddle of it, what i wrote is according to the requirement you asked in the question
• Chintan Soni: Yes. Just a little correction with your answer. I wanted "dealers" , "builders" instead of "x"
