Functions in Run JS

The following built-in JavaScript functions are available in a Run JS Action Type that is triggered by an event handler.

caution

Where possible, it is recommended to use the form based event handlers instead of writing these functions manually with JavaScript. Use these functions only when more complex conditional logic is required.

navigateTo()

This function allows the user to navigate to another URL when triggered. This functionality can also be triggered as its own form-based Action Type from an event handler.

navigateTo(URL, params, target)

Return Type: void

Parameters

Parameter Name	Type	Description	Default
URL	String	The URL to navigate to. You can also provide a path within the application, such as /detail-page/{{Table1.selectedRow.userId}}, to navigate without reloading the page.	None
params (optional)	Dictionary	Query parameters, used to pass context to the destination page.	None
target (optional)	String	"SAME_WINDOW" or "NEW_WINDOW", case-sensitive. Defines whether the page opens in the same or a new window.	SAME_WINDOW

info

Passing in key:value pairs can be omitted by using empty brackets {} allowing the target to be specified. E.g. navigateTo("URL", {}, "NEW_WINDOW")

Example

navigateTo("https://superblocks.com",{"user_id": 123, "email": "user@company_example.com"},"NEW_WINDOW");

info

If navigateTo() links to another Superblocks Application, the query parameters passed can be accessed with Global.URL.queryParams.<query_parameter_key>. (Learn more about the Global object metadata)

This gif shows an example of navigating to another application when a row is selected:

showAlert()

This functions shows an alert on trigger allowing you to specify the message and style of the alert. This functionality can also be triggered as its own form-based Action Type from an event handler.

showAlert(alert_message, style, durationSeconds, position)

Return Type: void

Parameters

Parameter Name	Type	Description	Default
alert_message	String	Message to be shown to the user.	None
style (optional)	String	"success", "info", "warning", "error", case-sensitive. The alert message style.	info
durationSeconds (optional)	Number	The duration before the alert is automatically dismissed. Specifying 0 will make the alert sticky to require explicit dismissal.	4 seconds
position (optional)	String	“bottomRight”, “bottom”, “bottomLeft”, “topRight”, “top”, “topLeft”	bottomRight

Example

showAlert("Woohoo, it was a success!" ,"success", 10, "bottomRight")

storeValue() - Deprecated

caution

StoreValue is deprecated. Please use Frontend Variables to store values in local browser storage.

This functions allows you to store a value in the local browser storage, similar to a frontend variable, then access it via the Global object.

storeValue(key, value, isTemporary)

Return Type: void

info

Use Global.store.key to access the value in another component or API step.

Parameters

Parameter Name	Type	Description	Default
key	String	A string containing the name of the key.	None
value	String	Value stored in the provided key. Set to undefined to delete the variable from local storage.	None
isTemporary (optional)	Boolean	Controls the persistence of the local store. Defaults to false so that data is available across sessions. Set to true for a temporary local store that is cleared when the page is refreshed.	false

Example

1. Set and call a local variable
   • Set the variable from an Input component with storeValue("animal",Input1.value)
   • Access the stored value using {{Global.store.animal}}
   • Clear the value by passing in an empty string as the value. E.g. storeValue("animal","")
   
2. Delete a local variable
   • Set the value of a variable to undefined to delete it. E.g. {{storeValue("animal", undefined)}}
   • Here is an example script to delete all local variables:

(function() {

var store_object = Global.store;

var store_keys_array = Object.keys(store_object);

for (let i in store_keys_array) {			
    storeValue(store_keys_array[i], undefined);
	}
})();

copyToClipboard()

This function allows you to copy text to the clipboard.

copyToClipboard(message)

Return Type: void

Parameters

Parameter Name	Type	Description	Default
message	String	A string to be copied to clipboard.	None

Example

resetComponent(component, resetChildren)

Return Type: void

Parameters

Parameter Name	Type	Description	Default
component	String	Components whose properties are to be reset to their default state.	None
resetChildren (optional)	Boolean	Reset all child components in addition to the component itself.	false

Example

resetComponent('Input1')

When resetting a Container component, you can choose to reset all children components within that container using resetChildren.

See also resetting components from event handlers.

component.set()

This function sets the property of a component to a specified value. This functionality can also be triggered as its own form-based Action Type from an event handler.

Visit the individual component pages for a list of the settable component properties, for example the Settable properties of the Table component.

component_name.set(propertyName, value)

Return Type: void
