it's the same right?

in this video he used this : $option.val($anchor.attr("href")); then he used a " prop()" so i conclude that this 2 lines are the same : we can use this 2 right??? $option.val($anchor.attr("href")); $option.prop("value",$anchor.attr("href"));

Kind of, but val() is specifically made for getting and setting the value of a form element.

From the jQuery docs for .prop():

"Properties generally affect the dynamic state of a DOM element without changing the serialized HTML attribute. Examples include the value property of input elements, the disabled property of inputs and buttons, or the checked property of a checkbox. The .prop() method should be used to set disabled and checked instead of the .attr() method. The .val() method should be used for getting and setting value."

It's also much clearer in your code, for other developers, or for when you refer back to it.
