Button

This page provides information on the button widget, enabling you to trigger actions or perform specific tasks with a simple click.

Content properties​

These properties are customizable options present in the property pane of the widget, allowing users to modify the widget according to their preferences.

Basic​

Label string​

Sets the text that appears on the button.

onClick​

Allows you to configure one or multiple actions (Framework functions, queries, or JS functions) to be executed when the button is clicked. You can chain multiple actions together, and all the nested actions would run simultaneously.

General​

Tooltip string​

Sets a tooltip that appears when the user hovers over the widget. It enables you to add hints or provide additional information for the button.

Visible boolean​

Controls the visibility of the widget. If you turn off this property, the widget is not visible in View mode. Additionally, you can use JavaScript by clicking on JS next to the Visible property to control the widget's visibility conditionally.

For example, if you want to make the button visible only when the user selects "Yes" from a Select widget, you can use the following JavaScript expression:

{{Select1.selectedOptionValue === "Yes"}}

Disabled boolean​

Prevents users from selecting the widget. Even though the widget remains visible, user input is not permitted. Additionally, you can use JavaScript by clicking on JS next to the Disabled property to control the widget's disabled state conditionally.

For example, if you want to allow only a specific user to click the button, you can use the following JavaScript expression:

{{appsmith.user.email=="john@appsmith.com"?false:true}}

Animate Loading boolean​

Controls whether the widget is displayed with a loading animation. When enabled, the widget shows a skeletal animation during the loading process. Additionally, you can control it through JavaScript by clicking on the JS next to the property.

Validation​

Google reCAPTCHA key​

Add a Google reCAPTCHA site key here to enable Google reCAPTCHA check to the button. The token is accessible from the API pane with the recaptchaToken key (see the Google reCAPTCHA docs). Read more about using Google reCAPTCHA Keys in Appsmith.

Google reCAPTCHA version​

Sets the Google reCAPTCHA version to use for the button, either v2 or v3.

Form settings​

Buttons can have some special behaviors when they're located within the boundaries of a Form widget. Its form-specific behavior is controlled by two of the button's properties:

Disabled invalid forms​

When this button property is turned on, the button remains disabled if the associated form contains any required fields that are incomplete or if any of the form fields contain input that is considered invalid.

For example, if you have a form with an Input widget whose Required property is turned on. If that input field hasn't been completed by the user, then the button won't be usable.

Reset form on success​

When this button property is turned on, the button can be used to reset all fields present in the form's area to their default state. This is useful for clearing inputs after the form is submitted.

Style properties​

Style properties allow you to change the look and feel of the button.

General​

Button variant string​

Specifies the style type of the button to indicate its significance.

Options:

  • Primary: Fills the button with color.
  • Secondary: Adds a colored border to the button while keeping the button itself white.
  • Tertiary: This option does not apply any specific styling changes to the button.

This property can be dynamically set using JavaScript by providing a string value of PRIMARY, SECONDARY, or TERTIARY.

Icon​

Select icon string​

Specifies the icon to be displayed on the button. Additionally, you can use JS to dynamically set the icon. You can refer to the documentation of blueprintjs to explore a wide range of available icons.

Position string​

This property allows you to configure the Icon's placement.

Options:

  • Left: Aligns the icon to the left side of the Label.
  • Right: Aligns the icon to the right side of the Label.

Placement string​

Determines the spacing between the Icon and the Label.

Options:

  • Start: The icon and label appear on the leftmost side of the button.
  • Between: The icon and label appear at opposite ends of the button's space.
  • Center: The icon and label appear in the center of the button space.

This property can be dynamically set using JavaScript by providing a string value of START, CENTER, or BETWEEN.

Color​

Button color string​

Represents the color of the button, specified as a CSS color value. Additionally, the font color can be programmatically modified using JavaScript functions.

Border and shadow​

Border radius string​

Applies rounded corners to the outer edge of the widget. If JavaScript is enabled, you can specify a valid CSS border-radius to adjust the radius of the corners.

Box Shadow string​

This property adds a drop shadow effect to the frame of the widget. If JavaScript is enabled, you can specify valid CSS box-shadow values to customize the appearance of the shadow.

Reference properties​

Reference properties enable you to access the widget's data and state using the dot operator in other widgets or JavaScript functions. They provide additional information or allow interaction with the widget programmatically. For instance, to retrieve the visibility status of a button widget, you can use Button1.isVisible.

text string​

Returns the value of the button's label property.

Example:

{{Button1.text}}

isVisible boolean​

Indicates the visibility state of a widget, with true indicating it is visible and false indicating it is hidden.

Example:

{{Button1.isVisible}}

isDisabled boolean​

It reflects the state of the widget's Disabled setting. It is represented by a boolean value, where true indicates that the widget is disabled, and false indicates that it is enabled for user interaction.

Example:

{{Button1.isDisabled}}

Methods​

Widget property setters enable you to modify the values of widget properties at runtime, eliminating the need to manually update properties in the editor.

These methods are asynchronous and return a Promise. You can use the .then() block to ensure execution and sequencing of subsequent lines of code in Appsmith.

setVisibility (param: boolean): Promise​

Sets the visibility of the widget.

Example:

Button1..setVisibility(true)

setDisabled (param: boolean): Promise​

Sets the disabled state of the widget.

Example:

Button1.setDisabled(false)

setColor (param: string): Promise​

Sets the background color of the button widget.

Example:

Button1.setColor('#FF0000')

setLabel (param: string): Promise​

Sets the label of the button widget.

Example:

Button1.setLabel('Click me!')
