Here's my json:
{"d":{"key1":"value1", "key2":"value2"}} Is there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?
The reason my json is structured like this is that the webmethod that I'm calling via jquery is returning a dictionary. If it's impossible to work with the above, what do I need to change about the way I'm returning the data?
Here's an outline of my webmethod:
<WebMethod()> _ Public Function Foo(ByVal Input As String) As Dictionary(Of String, String) Dim Results As New Dictionary(Of String, String) 'code that does stuff Results.Add(key,value) Return Results End Function

Keys must be strings, and values must be a valid JSON data type: string.
To access the JSON object in JavaScript, parse it with JSON. parse() , and access it via “.” or “[]”.
Use below code to find key is exist or not in JsonObject . has("key") method is used to find keys in JsonObject . If you are using optString("key") method to get String value then don't worry about keys are existing or not in the JsonObject . Note that you can check only root keys with has(). Get values with get().
To get a JSON object's key and value in JavaScript, we can use the JSON. parse method to parse the JSON object string into a JavaScript object. Then we can get a property's value as we do with any other JavaScript object.
You can use the for..in construct to iterate through arbitrary properties of your object:
for (var key in obj.d) { console.log("Key: " + key); console.log("Value: " + obj.d[key]); } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
