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 field value

Get the field’s value.

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

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.

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

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