Mojo.Widget.PasswordField
Namespace Detail
Overview
If you need a text field that will be used for passwords or some other type of confidential information, the Password Field provides many of the Text Field features but masks the display. Any entered text is displayed as a bullet, or "•" character. As with the Text Field the framework handles all of the editing logic within the field and generates a Mojo.Event.propertyChange event when the field has been updated.
Declaration
<div x-mojo-element="PasswordField" id="passwordFieldId" class="passwordClass" name="passwordName"></div>

Methods
To invoke a method on a widget, use the scene controller's get
method for the desired widget, and append mojo
followed by the method.
Example:
this.controller.get('myWidget').mojo.getValue()
Method | Arguments | Description |
---|---|---|
focus | none | Focuses the input part of the password field. |
blur | none | Blurs the input part of the password field. |
getValue | none | Gets the plaintext value of the password field. |
setText | String | DEPRECATED Sets the plaintext value of the text field. |
setValue | String | Sets the plaintext value of the text field. |
getCursorPosition | none | Returns an object with {selectionStart: int, selectionEnd: int} that describes the position of the cursor; if start is not equal to end, then there is text selected. |
setCursorPosition | start, end | Sets the cursor position in the input portion of the textfield; if start and end are not the same, then this will select the text between START and END; if start and/or end occur in invalid positions, they will be changed to valid positions at the end of the text if they were larger than the size of the value, or at the beginning, if they are smaller than the size of the value; empty text will result in a cursor at the start of the textfield. |
Set x-mojo-focus-highlight=true
on any parent div to have the focus class applied to it as well when the PasswordField widget becomes focused.
