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. The Image field value is stored as an object:
// returns the value as an object fd.field('Field1').value; //get the file name fd.field('Field1').value.name
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;
