jQuery UI button()方法用于转换HTML元素(如按钮，输入和锚点等)。它将HTML元素转换为可主题化的按钮，并自动管理鼠标的移动。它们全部由jQuery UI透明管理。
句法：
您可以以两种形式使用button()方法：
$(selector, context).button (options) Method
$(selector, context).button ("action", params) Method
button(选项)方法指定将HTML元素视为按钮。这里的选项?参数是一个对象，它指定按钮的行为和外观。
句法：
$(selector, context).button (options);
您可以使用JavaScript对象一次使用一个或多个选项。如果有多个选项，则必须使用逗号将它们分开，如下所示：
$(selector, context).button({option1: value1, option2: value2..... });
以下是可用于此方法的选项列表：
| Option | Description |
|---|---|
| disabled | If you set this option to true, it deactivates the button. By default its value is false. |
| icons | This option specifies that one or two icons are to be displayed in the button: Primary icons to the left, secondary icons to the right.Primary icon is identified by the primary property of the object, and the secondary icon is identified by the secondary property. By default its primary and seconadary value is set to NULL. |
| label | This option specifies text to display on the button that overrides the natural label. In the case of radio buttons and checkboxes, the natural label is the |
| text | This option specifies whether text is to be displayed on the button. If specified as false, text is suppressed if (and only if) the icons option specifies at least one icon. By default its value is true. |
让我们以一个示例来演示按钮小部件的功能，不向button()方法传递任何参数。

按钮(“操作”，参数)方法用于对按钮执行操作，例如禁用按钮。在这里吗?在第一个参数中指定为字符串(例如，“禁用”以禁用按钮)。
句法：
$(selector, context).button ("action", params);
以下是可与该方法一起使用的不同操作的列表：
| Action | Description |
|---|---|
| destroy | This action is used to remove the button functionality of an element completely and enforces the elements return to their pre-init state. This method does not accept any arguments. |
| disable | This action is used to disable the button functionality of an element. This method does not accept any arguments. |
| enable | This action is used to enable the button functionality of an element. This method does not accept any arguments. |

| option | This action retrieves an object containing key/value pairs representing the current button options hash. |
| option( optionName, value ) | This action sets the value of the button option associated with the specified optionName. |
| option( options ) | This action sets one or more options for the button. Here options is map of option-value pairs to set. |

让我们以一个示例来部署上述操作。在下面的示例中，我们演示了destroy()和disable()方法的用法。
