📥Information retreival

This section will teach you how to retreive saved information in SynoSurvey.

How to check saved answers

One main difference between SynoTool and SynoSurvey is the way we can recover the responded answers. Every answer in Survey is saved in an JSON, commonly know as a Javascript Object Notation.

If you are testing, you can inspect the page by clicking F12 or by doing right click > inspect .

This will open the developers tool for web programmers. Then, you need to go to the Elements tab. Right there you will find a script tag where they JSON is allocated. You can simply expand it to see what data has been saved from previous questions. This should look like this.

The variable holds the responses is called response. Each answer is wrapped into curly braces. This can contain different information regarding the type of the question. For more details, see the table below.

Structure of the saved information

Here is a table that describes the meaning of each variable in the JSON.

Read answers using Javascript

If you want to retreive the whole information in the json file you can use the following snippet.

Panelist & Parameters metadata

let guid = response.parameters.id;           // GUID
let source = response.parameters.source;     // Provider source, i.e. 1 (Syno), 2 (Cint Buyer API), 3 (Cint Access)
let gender = response.parameters.g;          // Gender where M: Male and F: Female
let year_of_birth = response.parameters.yob; // Year of birth in yyyy format
let panelist_id = response.parameters.pid;   // Panelist ID
let postcode = response.parameters.p;        // Postal code

🔘Single & ☑️ Multiple Choice

// Read all selected answer codes from a single/multiple choice
let selected_codes = response.answers.filter(answer => answer.questionCode == "Q1").map(answer => answer.code);

// Read all selected labels from a single/multiple choice
let selected_labels = response.answers.filter(answer => answer.questionCode == "Q1").map(answer => answer.label);

// Read all values from a single/multiple choice (for free answers in single/multiple choice)
let values = response.answers.filter(answer => answer.questionCode == "Q1").map(answer => answer.value);

⏺️ Single & ⏹️Multiple Choice Matrices

// Read all selected answer codes from a single/multiple choice matrix
let selected_row_codes = response.answers.filter(answer => answer.questionCode == "Q1").map(answer => answer.rowCode);

// Read all selected labels from a single/multiple choice matrix
let selected_row_labels = response.answers.filter(answer => answer.questionCode == "Q1").map(answer => answer.rowLabel);

// Read all selected answer codes from a single/multiple choice matrix
let selected_column_codes = response.answers.filter(answer => answer.questionCode == "Q1").map(answer => answer.columnCode);

// Read all selected labels from a single single/multiple choice matrix
let selected_column_labels = response.answers.filter(answer => answer.questionCode == "Q1").map(answer => answer.columnLabel);
