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 Number field value:

//return field value
fd.field('Field1').value;

//set field value
fd.field('Field1').value = 152;

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();

Number of decimal places

Specify the number of decimal places to which the number will be rounded:

fd.field('Field1').widgetOptions = {
    decimals: 3
}

Format

Specify the number format that is applied when a user leaves the control.

The number format is made up of format specifier and the number of decimals places. E.g. n3, c2.

fd.field('Field1').widgetOptions = {
    format: 'n2'
}

Learn more about the available number formats in the Kendo UI documentation.

Limit the range of number

Specify the minimum and maximum values that a user can enter:

fd.field('Field1').widgetOptions = {
    min: 5,
    max: 99
}

Restrict decimals

Specify whether the decimals length should be restricted during typing. The number of decimal places is defined by the decimals property value.

fd.field('Field1').widgetOptions = {
    decimals: 3,
    restrictDecimals: true
}

Rounded

Specify whether the value should be rounded or truncated. The default property value is true.

fd.field('Field1').widgetOptions = {
    round: false
}

Step

Specify the interval for adjusting the current value when using up and down arrows. The default property value is 1.

fd.field('Field1').widgetOptions = {
    step: 0.01
}
