The difference between $(). Ready () and wonload in jQuery

1. Execution time

_ window.onload can't be executed until all the elements on the page, including the image, have been loaded.

$(document) .ready () is executed after the DOM structure is drawn, and you don't have to wait until it is loaded.

2. The number of writers is different.

_ window.onload cannot be written at the same time, and if there are multiple _ window.onload methods, only one will be executed, and the following one will be executed.

$(document). Ready () can be written more than one at the same time, and can be executed.

_ window.onload has no simplified way of writing.

$(document) .ready (function () {}) can be simplified to $(function () {}).
