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.

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

Parameter NameTypeDescriptionDefault
URLStringSuperblocks Application URL to navigate to.None
params (optional)DictionaryQuery 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")

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

If navigateTo() links to a 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 NameTypeDescriptionDefault
alert_messageStringMessage to be shown to the user.None
style (optional)String"success", "info", "warning", "error", case-sensitive. The alert message style.info
durationSeconds (optional)NumberThe duration before the alert is automatically dismissed. Specifying -1 will make the alert sticky to require explicit dismissal.4 seconds
position (optional)String“bottomRight”, “bottomCenter”, “bottomLeft”, “topRight”, “topCenter”, “topLeft”bottomRight

Example

showAlert("Woohoo, it was a success!" ,"success", 10, "bottomRight")
Trigger custom success and error alerts with onClick event handler of a button

storeValue() - Deprecated

caution

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

This functions allows you to store a value in the local browser storage, similar to a state 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 NameTypeDescriptionDefault
keyStringA string containing the name of the key.None
valueStringValue stored in the provided key. Set to undefined to delete the variable from local storage.None
isTemporary (optional)BooleanControls 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","")
      Use Global Store to store and retrieve local variables
  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)

Parameter NameTypeDescriptionDefault
messageStringA string to be copied to clipboard.None

Example

copyToClipboard(Button1.text)

resetComponent(component, resetChildren)

Return Type: void

Parameters

Parameter NameTypeDescriptionDefault
componentStringComponents whose properties are to be reset to their default state.None
resetChildren (optional)BooleanReset all child components in addition to the component itself.false

Example

resetComponent('Input1')
Reset a component to default values

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.
