Extract Part Of A Number From Input And Set As Another Field Value

In this example guide, we will explain how to extract part of a number from the input and set it as another field value.

When a user enters a number value in the first field, the second field will extract and show a part of the first field's input value from position number three to eight.

Drag and drop a Number, a Text and a JavaScript field. And rename the fields as shown below.

Click the pencil icon of the JavaScript field and paste the code. Save the changes.

Please use the below code:

// Listen to Formyoula field changes based on label
window.formyoula.form_fields[ 'Number Field' ].on( 'input:set:success', function( field ) {
  // Set the number field value to subset
  window.formyoula.form_fields[ 'Part Of Number Input' ].set( { 
    value: this.get( 'value' ).substring( 2, 8 )
  } );
} );

Try the form.

The second field will show the value of position numbers three to eight from the input value of the first field.
