There are only parentheses after val, which is equal to getting the Value of input

Placing a space in the brackets is equivalent to emptying the value

Writing any data in the brackets is equivalent to resetting the Value

3, $(‘input’).val(“Hello”)

Return the attribute value through attr, so you can get the value of Value

Set attribute value to Value by attr

5, $(‘input’).attr(“value”,”Hello”)

attr can set multiple attribute values

6, $(input).attr({
class:c1, class:c2,…})
