JQuery are basically used in project, aways defined events callback like $(document).on('ready', function(){}) when document reday. but there has one things Interest me, what is different window.onload with document.ready ?
window.onload
This event must wait for all elements on the page to loaded then execute this function after rendering
document.ready
This event be executed as soon as the dom is loaded ignore other Asset(images,videos) if ready
Also confuse? let's talk a simple example
Simple example
We create new chrome tab with url request page, this page havs many images.
When the page DOM are loaded but images, window.ready won't be trigger until images loaded browser will trigger this callback
As long as page DOM is loaded even if image is not loaded browser will trigger document.ready
One words
window.ready : trigger when page all DOM and Asset(images, videos) are rendered ready
document.ready trigger when page loaded render process rendered even if Asset(images, videos) not ready
Hope it can help you :)
