Likert Scale

Name

A unique identifier for the control.

The Name property is used in JavaScript to select a specific control.

fd.spRendered(function(){
    //can access the control using its Name:
    fd.control('Control1');
 });

Required

Define whether the control will be required to submit the form or not:

Required status can also be changed directly on the form via the Asterisk button:

//returns the control's required status as true/false
fd.control('Control1').required;

//sets the control's required status
fd.control('Control1').required = true;

Type

Defines the type of answer input.

Select the input type from a dropdown:

• Radio — allows a user to select only one option from the list of answers:

  

• CheckBox — allows a user to select one or more options from the list of answers:

  

• String — allows a user to write a comment for each answer option:

  

• Number — allows a user to enter a number for each answer option:

  

• DropDown — allows a user to select an answer from a predefined list of options:

  

  When you select the DropDown from the list, you will see the additional Options property.

  Add a list of options to the Options property. Each option should be on a new line, as shown here:

  

Questions

Stores a list of questions.

Add a list of questions to the Questions property. Each question should be on a new line, as shown here:

Width

The property defines the width of the control in pixels.

If left blank, the control takes up the entire available width in the current grid cell.

Answers

Stores a list of answers.

Add a list of answers to the Answers property. Each answer should be on a new line, as shown here:

Class

Add a CSS class to the control, which comes in handy with CSS or even JavaScript code. This will work like class attribute for an HTML tag.

Same class can be applied to multiple controls, and then you can use CSS to modify the appearance of these controls.

Style

Add custom CSS style to the control. This will work like style attribute for an HTML tag.

You can apply different styles to the control. For example, the following style will add a shadow under the control:

box-shadow: 0 9px #999;

And this makes the control invisible to user (but still usable with JavaScript):

display: none;

Save to

Select an existing Multiline Plain Text column or create a new one in the current SharePoint List to store control’s data. It will automatically render control in SharePoint list view.

Read-only

Define whether a user can view or edit the contents of the control:

Formatting

The property contains a JSON object that defines how the data is displayed in the list view.

Get or set control value

If the answer type is Radio, the control value is stored as an array of strings.

The array length is equal to the number of questions.

Get or set the value using the code:

//get answers as an array of strings
fd.control('Control1').value;

//set Radio Type Likert scale value, which has five questions
fd.control('Control1').value = ['Good', 'Okay', 'Good', 'Superb', 'Awesome'];

//set Radio Type Likert scale value, which has three questions
fd.control('Control1').value = ['Good', 'Okay', 'Awesome'];

If the answer type is CheckBox, the control value is stored as a jagged array (array of arrays).

The array length is equal to the number of questions.

Get or set the value using the code:

//get answers as an array of arrays
fd.control('Control1').value;

//set Checkbox Type Likert scale value, which has two questions
fd.control('Control1').value = [
    ['Okay', 'Cool'],
    ['Cool'],
    ['Very Poor', 'Very Cool', 'Amazing'],
    ['Superb', 'Awesome']
];

If the answer type is String, Number or DropDown, the control value is stored as a jagged array (array of arrays).

The array length is equal to the number of questions. The member arrays length is equal to the number of answer options.

Get or set the value using the code:

//get answers as an array of arrays
fd.control('Control1').value;

//set String Type Likert scale value, which has two questions and four answer options
fd.control('Control1').value = [
    ['', 'Okay', 'Cool', ''],
    ['', '', 'Cool', 'Very Cool']
];

//set Number Type Likert scale value, which has five questions and three answer options
fd.control('Control1').value = [[2, 1, 2],[0, 5, 3],[0, 1, 0],[0, 0, 6],[1, 0, 0]];

Access HTML element inside the control in order to modify it, hide it, or do something else.

//access control's HTML

Clear the control value.

fd.control('Control1').clear();

Handle change event

    //log changes to browser's console
    console.log('New value: ' + value);
});

Make control required

Make a control required or optional:

//make control required
fd.control('Control1').required = true;

//make control not required
fd.control('Control1').required = false;

//disable control
fd.control('Control1').disabled = true;

//enable control
fd.control('Control1').disabled = false;
