How to use the setTimeout function in the Salesforce Lightning Component?

The setTimeout function refers to a native JavaScript function that creates a timer to execute the callback function, thereby calling the function on termination of the timer. You can use $A.getCallback() to wrap a code that alters a lightning component external to the usual re rendering lifecycle, including the setTimeout9) call. The $A.getCallback() call guarantees that the infrastructure rerenders the altered component and executes the enqueued tasks. The example where you can use $A.getCallback() is calling window.setTimeout9) in the event handler to process the logic after time delay. This places the code outside the infrastructure’s call stack.

The below example sets the attribute on the component to true after the time delay.

window.setTimeout( $A.getCallback(function() { cmp.set("v.visible", true); }), 5000 );

You can try the below-mentioned code:

action.setCallback(this, function(response){ var state = response.getState(); if (state === "SUCCESS"){ isValid = response.getReturnValue(); window.setTimeout( $A.getCallback(function() { alert(isValid); }), 5000 ); $A.get("e.force:closeQuickAction").fire(); $A.get('e.force:refreshView').fire(); } else{ console.log("Unknown error"); component.set("v.errorMessage", "Unknown error"); } helper.hideSpinner(component); });
