The code has no error, and that is the inferable statement we can derive from calling a function on each page load. The parameters of our function are some other functions.ĭocument.getElementById('output').innerHTML = func(f1,f2) įrom the output scenario, whenever the Run with JS is pressed, it gives a similar experience of loading a webpage. The load event on the window occurs once the page and all the resources are loaded. So, JavaScript can be applied to elements at this stage.
After that, we set an onload event for changetext () function in tag. In brief, the page load events are the following: The DOMContentLoaded event happens on the document when the DOM is ready. We will use an HTML code section and an individual JavaScript code section. First, we create a changetext () function to change the text of the demo element. The following examples will explain the function of the window.onload property differently. JavaScript Call Function That Takes Functions as Argument on Load So, you can use it anywhere according to your convenience. It is most likely works as a parameter of ensuring an error-free code block in your HTML. In this instance, the script portion was added inside the HTML body, and as you can see, on every load of the webpage, the console has a value, which explains that the overall code is functioning.Īdditionally, the basic use case for window.onload is to ensure that the page is successfully loading each time. You can, either way, use your browser and preferable editor.ĭocument.getElementById('output').innerHTML = func(x,y) Static methods are often used to create utility functions for an application, whereas static properties are useful for caches, fixed-configuration. Static members (properties and methods) are called without instantiating their class and cannot be called through a class instance. Alongside, the coding drive experimented in jsbin is to grab a better understanding. The static keyword defines a static method or property for a class. The basic way to know that your function is being called is to check the console panel. This convention depends on the browser object window and its property onload. A function that can be called whenever the web page is loaded. Here, we will be using a function that takes variables as arguments. JavaScript Call Function That Takes Functions as Argument on Load. JavaScript Function That Takes Variables as Parameter And every time we reload the web page, the console panel will respond to a given statement directed by the window.onload property.
The basic way to know that your function is being called is to check the console panel.įor the demonstrative example, we will consider an HTML structure, where we want to visualize how our output will be. JavaScript Call Function That Takes Functions as Argument on LoadĪ function that can be called whenever the web page is loaded.JavaScript Function That Takes Variables as Parameter.
