Javascript Data Format, Is This JSON?

Some jquery plugins I use require a data of this format as its input type

[
{image : '1.jpg', title : 'Title', url : '', age : 24, location : 'US', name : 'John', description : 'Long Text'},  
{image : '1.jpg', title : 'Title', url : '', age : 24, location : 'US', name : 'John', description : 'Long Text'}, 
{image : '1.jpg', title : 'Title', url : '', age : 24, location : 'US', name : 'John', description : 'Long Text'}
]

My question is, what is this kind of data and how to create it? Is this still JSON? because when I try to pass json_encoded array with PHP and get it with jquery, I get this format :

[
{'image' : '1.jpg', 'title' : 'Title', 'url' : '', 'age' : 24, 'location' : 'US', 'name' : 'John', 'description' : 'Long Text'},  
{'image' : '1.jpg', 'title' : 'Title', 'url' : '', 'age' : 24, 'location' : 'US', 'name' : 'John', 'description' : 'Long Text'}, 
{'image' : '1.jpg', 'title' : 'Title', 'url' : '', 'age' : 24, 'location' : 'US', 'name' : 'John', 'description' : 'Long Text'}
]

Notice the quotes that wrap the variable name. That makes the code not working.

I'm going to put this is another answer so it's easier to read...

In this instance you don't want to generate JSON, the plugin requires a literal array as Matt Ball said.

Basic code format will be something similar to this (will be semi .NET sorry...): 

public Array GenerateData()
{
// Generate dynamic data here and return as a list / array
}

// Get the data
Array dynamicData = GenerateData();

// Create the template
string template = "[";

// For each item in list, add to the template
foreach (item in dynamicData)
{
    template += "{ image : '" + item[0] + "', title : '" + item[1] + "', url : '" + item[2] + "', age : " + item[3] + ", location : '" + item[4] + "', name : '" + item[5] + "', description : '" + item[6] + "' },"
}

// Add closing brack - may need to trim off last comma also?
string template = "]";

Then embed the template string in your plug intitialisation.

Doesn't appear that the plugins are requiring JSON - looks more like a dictionary of some kind.

Valid JSON looks something similar to: {"name":"John", "age":50}

You will probably need to build a custom helper method to format the data correctly for your plugins, can give you a hand if you provide a bit more of your source code :)

The first is a JavaScript array literal which contains object literals. It is not JSON.

The second is also an array literal that contains objects. It's closer to JSON, but is not 100% valid, since JSON requires that all strings are double-quoted. For example, this is valid JSON:

[{"image": "1.jpg", "title": "Title" }]

If you're unsure if you're looking at valid JSON, you can always run it through JSONLint and see for yourself.
