How to validate a form using JSON Schema?

Question

I want to validate the input from an HTML form using a JSON Schema describing it. I'm using Gary Court's JSV to validate it and it returns an error consistently. I used JSON Schema Lint (jsonschemalint.com) to check my schema. In Chrome Schema Lint tells me my schema is valid, but in Firefox, Safari & Opera the website tells me that my schema is valid JSON but not valid JSON schema. Can anyone help me out. My schema is below. UPDATE 8/6/13 Thank you for all your replies. My updated JSON (updated below) is now validating in all browsers. However I am still getting the following error from JSV: ``` Report {errors: Array[1], validated: Object, instance: JSONInstance, schema: JSONSchema, schemaSchema: JSONSchema…} errors: Array[1] 0: Object attribute: "type" details: Array[1] 0: "object" length: 1 __proto__: Array[0] message: "Instance is not a required type" schemaUri: "http://json-schema.org/draft-03/hyper-schema#" uri: "urn:uuid:808fe74b-b0d0-4774-8975-289f105dfeaa#" __proto__: Object…

Accepted Answer

I checked it again in the JSON schema website and it seems the name `"Turbidity (ntu)"` is not a valid key. `JSON schema`does not 'like' parentheses in a key. It works if you leave the parentheses out, like in `"Turbidity ntu"`.

I was just commenting on @pmagunia's entry when he apparently withdrew it. He remarked that `required` can only contain boolean values. It seems to me that the `required` property at the top is actually superfluous. I just tested it in JSON Schema Lint and the schema is said to be valid without it. But `required` can definitely only hold boolean values. Your array

```
[ "TestSite", "Date of Test", "Latitude", "Longitude" ]
```

was transformed by JSON Schema Lint into an unquoted string

```
TestSite,Date of Test,Latitude,Longitude
```

which will definitely be invalid JSON!
