What is event load?
The load event is fired when the whole page has loaded, including all dependent resources such as stylesheets and images. This is in contrast to DOMContentLoaded , which is fired as soon as the page DOM has been loaded, without waiting for resources to finish loading.
What is DOMContentLoaded event?
The DOMContentLoaded event fires when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading.
What is DOM ready?
DOM ready means that all the HTML has been received and parsed by the browser into the DOM tree which can now be manipulated. It occurs before the page has been fully rendered (as external resources may have not yet fully downloaded – including images, CSS, JavaScript and any other linked resources).
Why the form1_load () event is used?
It “Occurs before a form is displayed for the first time.” and “You can use this event to perform tasks such as allocating resources used by the form.” You can consider it as “initialization”. For example, if you want to determine whether a label “__ , Sir” should use “Morning, Afternoon” .
What is the difference between load and show method?

What is DOM load time?
DOM Load. The time from when a request is sent until the browser has downloaded the page’s HTML and finished constructing the Document Object Model (DOM). The timer stops when the DOMContentLoaded event is fired.
What is the sequence of DOM event life cycle?
The event journey starts at the Document, moves down to the HTML element, moves to the Body element, and finally gets to the Button element.
What is the purpose of the beforeunload event?
The beforeunload event is fired when the window, the document and its resources are about to be unloaded. The document is still visible and the event is still cancelable at this point. This event enables a web page to trigger a confirmation dialog asking the user if they really want to leave the page.
What is before load event in Salesforce?

What is a user event script before load trigger?
User Event Scripts are one of the most common script types to work with. In the next several blogs I will walk through some example User Event scripts, and this first blog will introduce the basic setup of the User Event Script Before Load trigger. The beforeLoad function in User Event Scripts triggers when a record loads in your NetSuite instance.
Why attach an event handler/listener to a document’s beforeunload event?
Attaching an event handler/listener to window or document’s beforeunload event prevents browsers from using in-memory page navigation caches, like Firefox’s Back-Forward cache or WebKit’s Page Cache. The HTML specification states that calls to window.alert(), window.confirm(), and window.prompt() methods may be ignored during this event.
