Auto Focus

Animate loading
When turned off, the widget will load without any skeletal animation. You can use a toggle switch to turn it on/off. You can also turn it off/on using javascript by enabling the JS label next to it.
Let's understand the widget properties in detail.
Allow Currency Exchange
It enables/disables the currency dropdown next to the input box. If you enable this property, the user can change the currency from the dropdown.
Placeholder
You can set a proxy text/value inside the input box using the placeholder property. It can be any message or hint for the expected input.
Default text
This property lets you set a default value for the widget before the user has made any changes. The value must be a number datatype.
Regex
Using Regex or Regular expression property, you can set specific constraints on the input you expect from the user.
For example, let’s add a regular expression for entering a price in multiples of 5.
.*[05]$
If you enter a value other than a multiple of 5, the widget will show an error message “invalid input.”
Error Message
If a user enters an incorrect value, the input widget shows a message “invalid input.” You can change this message by using the Error message property to provide better feedback on the input given by the user.
Required
Entering a value in the input box is mandatory when the required property is enabled. You can also write a JS code to link this property to a user action. Click on JS next to the Required to write JavaScript code.
For example, let’s drag a checkbox widget checkbox1 onto the canvas and bind it to the Required property. To enable the Required when the user checks the checkbox, add the following JavaScript code in the Required property:
{{Checkbox1.isChecked}}
When you tick the checkbox, it will enable the Required property, and the input box will show an error message “This field is required” if you have not entered any input.
Visible
Visible controls the widget’s visibility on the app’s page. The widget will not be visible on the published app if you turn off this property. You can also write a JS code to link Visible’s functionality to a user action. Click on JS next to the Visible to write JavaScript code.
For example, let’s drag a checkbox widget checkbox1 onto the canvas and bind it to the Visible property. To enable the Visible when the user checks the checkbox, add the following JavaScript code:
{{Checkbox1.isChecked}}
When you tick the checkbox, it will enable the Visible property, and the input box will be visible in the app.
Disabled
It prevents the user from entering values in the widget. The widget will be visible (if Visible is enabled), but user input will not be allowed. You can also write a JS code to link Disabled’s functionality to a user action. Click on JS next to the Visible to write JavaScript code.
For example, let’s drag a checkbox widget checkbox1 onto the canvas and bind it to the Disabled property. To enable the Disabled when the user checks the checkbox, add the following JavaScript code:
{{Checkbox1.isChecked}}
When you tick the checkbox, it will enable the Disabled property and prevent a user input in the input box.
Reset on Submit
When Reset on Submit is enabled, the widget resets or clears the entered input after the user submits it.
Let’s use the event onSubmit to show a message when input is submitted. You’ll see once the user submits and the message pops up, the currency input widget will reset itself to its original state.
Auto Focus
When you enable Auto focus, the cursor focuses on the input box whenever the widget is loaded.
Binding Properties
These properties allow you to bind your currency input widget with any other widget in queries or JS objects.
These properties help you share values between widgets and allow you to access the widget property within Queries or JS functions easily.
