1.ELEMENT.ATTR (name)
Description: Used to get the Name property value of an element, as in the example $ ("#divTest"). attr ("id") gets the ID value of the divtest.
2.element.attr (Name,value)
Description: Used to set the Name property value for an element, such as $ (": Text") in the example. attr ("Value", $ ("#divTest"). attr ("id") assigns the Divtest ID value to the value of the text form.
Note: The example (": Text") is used to get the element with the input form type text, and other forms can be obtained by the same method, such as <input type= "button"/> is available in $ (": Button"). The return value is array (element), and you can also use $ (": input") to get all the input elements ... To get and set the text and value values of an element in jquery, you can also use Element.text ()/element.text (value), Element.val ()/element.val (value), Use the same as element.html (), if you have questions can be thread, I will explain
3.element.attr (name,function)
Description: The Name property value used to set an element is similar to the previous one, except that the value here can be written as a function and more flexible.
4.element.remove (name);
Description: The Name property used to delete an element.
