How to call a function in JavaScript on page load?

The function can be defined within the content of any element, but the best practice is to put it in a javascript file, possibly one that is loaded in the section of your website. The function can be called using the onload event handler, which is fired when the page has been loaded completely.

You can use the following code: You can use a few JavaScript techniques for calling a function when the page is loaded. One of the most common techniques is to use the ready event. This event is fired when the page is ready to be displayed to the user.

The event handler for the ready event receives a single argument: a reference to the jQuery object that represents the DOM element that loaded the page. There are several ways to call a function when the page is loaded. One of the ways is by including the JavaScript function in the section of the HTML file.

This method is similar to the method of adding the function to the window object, but the function is called before the body of the page is parsed. The onload event handler can also be defined in a JavaScript file that is loaded in the section of the page.

How to run a JavaScript function on load?

If you want to run a javascript function when the page loads, rather than when the page is rendered, you can use the DOMContentLoaded event. The DOMContentLoaded event is fired when the DOM is finished loading and all the page’s elements are available.

The DOMContentLoaded event fires when HTML parsing is finished and before the JavaScript code is executed. You can call a JavaScript function when the page loads by using the window.onload function. You can place the function call in the head section of your page.

That way, your JavaScript code will run as soon as the page loads and before any other JavaScript code runs.

Run a JavaScript function on page load?

To run a JavaScript function on page load, you can use any of the techniques listed in the previous section. jQuery offers two ways to run a JavaScript function when the page loads — $(document).ready() and window.onload.

The difference between them is that the former runs the function once the DOM has loaded, whereas the latter runs the function when the window has finished loading. Short answer: You can trigger JavaScript when the page loads by adding the JavaScript to the section of the page. This is a good place to put code that needs to run on page load, but it’s not the only place.

You can also trigger JavaScript on page load in the body of the HTML. The jQuery $(document).ready() function is a good choice if you want to run JavaScript when the DOM (Document Object Model) is ready to be manipulated. This is the point at which the page’s HTML elements have been parsed and added to the page.

It’s usually the best place to put JavaScript code that refers to elements by their unique IDs or refers to DOM nodes by their position within the DOM tree.
