Choice

In the SharePoint column settings, you can choose how the field appears on the form:

Drop-down menu

Radio buttons

For a Drop-down display format, you can also define whether a user is allowed to select a single option or multiple options.

Tip

Display

The property defines how the choice field that allows multiple selections appears on a form:

Columns

For radio buttons and checkboxes, you can specify the layout of the options.

By default, the options are grouped into three columns.

JavaScript framework

In this section, you can find basic examples of how to work with the SharePoint fields using JavaScript.

For more examples, check out Working with form fields in JavaScript article. If you are not familiar with the JavaScript framework, get started with the JavaScript basics.

Note

The field is only accessible once the form is rendered, so all calls to the field must be inside fd.spRendered event:

fd.spRendered(function(){
    //make field required
    fd.field('Field1').required = true;
});

Get or set field value

Get or set the field’s value that allows selection of only one option:

//return field value as a string
fd.field('Field1').value;

//set field value
fd.field('Field1').value = 'Item 1';

Get or set the field’s value that allows multiple selections:

//return field value as an array of string
fd.field('Field1').value;

//set field value
fd.field('Field1').value = ['Item 1', 'Item 2'];

Get the display value

Returns the formatted value of a field when it is displayed on the Display form or is in read-only mode.

//returns selected choice as a string
fd.field('Field1').displayValue;

Handle change event

Execute a function when a field value has been changed:

fd.field('Field1').$on('change', function(value) {
    //log new value to browser's console
    console.log(value);
});

Make field required

Make a field required or optional:

//make field required
fd.field('Field1').required = true;

//make field not required
fd.field('Field1').required = false;

Disable field

Make a field non-editable. The field value can still be changed with JavaScript and saved:

//disabled field
fd.field('Field1').disabled = true;

//enable field
fd.field('Field1').disabled = false;

Get HTML element

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

//access field's control
var htmlField = fd.field('Field1').$el;

//access field's block, which includes title and control
var htmlFullField = fd.field('Field1').$parent.$el;

Hide field

Hide a field from a user. The field value can still be accessed and changed with JavaScript.

//hide field
fd.field('Field1').hidden = true;

//show field
fd.field('Field1').hidden = false;

Clear field

Clear field value.

fd.field('Field1').clear();

You can access the widget used by the field. The widget is based on Kendo UI DropDownList in regular mode, with allow user value option enabled it is based on Kendo UI ComboBox, and in multiple selection mode it is based on Kendo UI MultiSelect.

// get the widget
fd.field('Field1').widget;

// change the widget's configuration
fd.field('Field1').widgetOptions = { template: '<span style="font-weight: bold">#: data #</span>' }

widgetOptions is the same as widget.setOptions({}) but can be defined before widget initialization.

Columns

For radio buttons and checkboxes, specify the number of columns by which the options will be grouped:

//group by 2 columns
fd.field('Field1').columnsNumber = 2;

Limit number of selectable options

For multiple selection mode, you can limit the number of selectable options with field validation:

//prevent user from selecting more than 3 options
fd.field('Field1').addValidator({
    name: 'Field1 options validation',
    error: 'No more than 3 options',
    validate: function(value){
        if(value.length > 3){
            return false;
        }
        return true;
    }
});
