jQuery Interview Question: Difference between document.ready() and window.load() functions
When working with jQuery, it is important to understand the difference between document.ready() and window.load() functions.
The $(document).ready()
function in jQuery is called when the DOM (Document Object Model) has been loaded and is ready for manipulation. This means that it is executed as soon as the DOM is ready, even if the images and other external resources are not yet loaded.
On the other hand, the $(window).load()
function is called when the complete page, including all images and external resources, has been fully loaded. This function will wait for all elements on the page to be ready before executing.
In summary, $(document).ready()
function is triggered as soon as the DOM is ready for manipulation, while $(window).load()
function waits for all page resources to load before executing. It is recommended to use $(document).ready()
for most jQuery operations to improve performance and efficiency.
