It is possible to perform actions such as disabling a field or displaying an error on a field by changing the properties of the event object and returning it. This section explains the available actions.

If the event handler overwrites values in the fields of the record object and returns the event object, the record is saved with those values in the object.

Sample

When saving an inline edit of a record, overwrite the field text_0 and text_in_table_0 with a specified string. text_in_table_0 is a field that lies within a table with field code of table_0.

kintone.events.on('app.record.index.edit.submit', function(event) {
  var record = event.record;
  record.text_0.value = 'Overwrite with this string';
  record.table_0.value[0].value.text_in_table_0.value = 'Overwrite first record in table';
  return event;
});

Fields that cannot be Overwritten

Even if the below fields are overwritten in the handler and returned, they will not take effect on the record itself

• Record number
• Created by
• Created datetime
• Updated by
• Updated datetime
• Status
• Assignee
• Calculated
• Text Fields with the "Calculate automatically" option
• Attachment
• Lookup
• The Field Mappings targets of the Lookup field

If the event handler inputs true/false in the disabled of a field of the record object and returns the event object, editing of those fields will become enabled/disabled.
Nothing will happen if this is applied to a field where you have no editing permissions.

Sample

Disable the editing of the text_0 field when a value is selected in the drop down field dropdown_0, during an inline edit of a record.

kintone.events.on('app.record.index.edit.change.dropdown_0', function(event) {
  var record = event.record;
  record.text_0.disabled = true;
  return event;
});

Fields where editing cannot be enabled/disabled

Even if the below fields are returned with the disabled as true/false, they will not take effect on the record itself.

• Record number
• Created by
• Created datetime
• Updated by
• Updated datetime
• Status
• Assignee
• Calculated
• Text Fields with the "Calculate automatically" option

If the event handler inputs an error message in the error of a field of the record object and returns the event object, an error message is displayed for the corresponding field.
In this case, the Overwrite field values and the Enable/Disable field edits are canceled.
To remove error messages from fields, input null into the error of the field, and return the event object.

Sample

Show an error message for the fields text_0 and dropdown_0 when saving an inline edit for a record.

kintone.events.on('app.record.index.edit.submit', function(event) {
  var record = event.record;
  record.text_0.error = 'This is an error message';
  record.dropdown_0.error = 'This is also an error';
  return event;
});

Fields that don't show error messages

Even if the below fields have error messages inputted by the handler and the object is returned, they will not take effect on the record itself.

• Record number
• Created by
• Created datetime
• Updated by
• Updated datetime
• Status
• Assignee
• Calculated

If the event handler inputs an error message in the error of the event object and returns the event object, an error message is displayed for the record.
In this case, the Overwrite field values and the Enable/Disable field edits are canceled.

Sample

Show an error message for the record when changing a drop-down field during an inline edit of a record.

kintone.events.on('app.record.index.edit.change.dropdown_0', function(event) {
  event.error = 'This is an Error Message!';
  return event;
});

If a redirect URL is specified, the event handler will redirect the page to the specified URL after returning the event object.

If null is specified, the page will not redirect.

Sample

Redirect the user's web browser to "https://kintone.dev" after the record is saved.

kintone.events.on('app.record.index.edit.submit.success', (event) => {
  event.url = 'https://kintone.dev';
  return event;
});

These actions are only available on the Desktop, and not on the mobile.

If the event handler overwrites values in the fields of the record object and returns the event object, the fields of the record are updated with those values in the object.

Sample

When the process has progressed, overwrite the field text_0 with a specified string, overwrite the first line of the table, and add values into text_in_table and number_in_table that are inside a table, as a new line.

  // Add a row to the end of a Table field
  var newRow = {
    value: {
      text_in_table: {
        type: 'SINGLE_LINE_TEXT',
        value: 'New value for new row'

        value: '777'
      }
    }
  };
  record.Table.value.push(newRow);
  return event;
});

Note that when adding a new row to the table, all fields in the table must be specified, and the type of each field must also be specified.

Fields that cannot be Overwritten

Even if the below fields are overwritten in the handler and returned, they will not take effect on the record itself.

• Record number
• Created by
• Created datetime
• Updated by
• Updated datetime
• Status
• Assignee
• Calculated
• Text Fields with the "Calculate automatically" option
• Attachment
• Lookup
• The Field Mappings targets of the Lookup field

Notes

• If an empty string is specified for the radio button field, the default value of the field will be inputted.
• Values of the fields can be overwritten, even if the editing of the field has been disabled.
• If you do not have permission to add values to a particular field, the field change written in the script will not take effect for that field.
• If the handler does not return the event object, the fields will not be updated.
• If there are several handlers, the returned values from the last handler will take effect.

A field error message is displayed, if the even handler inputs a message in the error property of a field in the record object, and the object is returned. In this case, the overwriting of field values is canceled.
To remove error messages from fields, input null into the error of the field, and return the event object.

If the event handler overwrites values in the fields of the record object and returns the event object, the fields of the record are updated with those values in the object.

• #INVALID will be returned in event objects if non-numeric values are set in Number fields
• Setting the value with an invalid value using Event Objects or JavaScript API will result in an error.
• If the value is set to #INVALID!, the value will not change.
• In the mobile view, if whitespaces are entered before or after a value, they will be sanitized.
• When whitespaces are sanitized, as long as the final value does not change, events will not be triggered.

If the event handler overwrites values in the fields of the record object and returns the event object, the fields of the record are updated with those values in the object.

Sample

After opening the record edit page, overwrite the field text_0 with a specified string, overwrite the first line of the table, and add values into text_in_table and number_in_table that are inside a table, as a new line.

• #INVALID will be returned in event objects if non-numeric values are set in Number fields
• Setting the value with invalid values using Event Objects or JavaScript API will result in errors.
• If the value is set to #INVALID!, the value will not change.
• In the mobile view, if whitespaces are entered before or after a value, they will be sanitized.
• When whitespaces are sanitized, as long as the final value does not change, events will not be triggered.

The following non-numeric values can be used when updating the value in the Number fields:

• undefined null: The value in the Number field will become empty.
• #INVALID!: The value in the Number field will not be changed.

Other non-numeric values are treated as invalid values in the Number field.

By returning the Web browser Promise, the next operations can be processed after waiting for asynchronous processes. When multiple event handlers are registered for the same Kintone event, if an error occurs and the Thenable object is rejected, subsequent event handlers will be canceled.
