How to get/set value to HTML form element in jQuery?

Lets say we have a html form textbox with id as "txtName".

To get the value

$("#txtName").val(),

To set the value

$("#txtEditName").val("My Value");

We can use the above code for dropdownlist or listbox as well.

To pre-select a DropDownList/ListBox value use

$("#drop1 option:contains("myvalue")").attr('selected', 'selected');

Thanks
