jQuery on Page Loading

If you want something to happen when your page loads on your browser, you have to use the function ready ( ). It informs your browser to execute commands within the parentheses that follow the ready command.

As you can see in the following codes, the function ready ( ) is called in jQuery and the codes within it are executed:

You have to use the functions in jQuery to obtain src attributes from <img> elements and show them as texts in <div> elements. In addition, you have to keep in mind that the function ready ( ) has commands that search for <img> elements as well as save src attribute values within variables.

As you can see in the above given example, a selector is used on the following line to find the <div> tag as well as set the text within the <div> element. Such code runs while the page that contains HTML codes gets loaded.

During this time, forms of media, such as images, often still load. However, the moment the HTML codes start to load, the event ready( ) starts to run.

Programmers generally place event codes within the function ready ( ), but you can choose to not use it. You may only use the codes found inside it. Then again, it is still recommended that you ensure for HTML codes to be loaded prior to executing other codes. You have to put your event codes within the function ready( ) so that you can make sure that all HTML codes are there.
