Jquery dynamically changes the use of src and Attr of a bitmap_jquery

Today I want to use Jquery to dynamically change the src of a bitmap and found that css is not easy to use. Looking at the Jquery document, it seems that css is used to set style attributes, such as color, font, background, etc., while attr seems to be able to operate all attributes, including Jquery Unencapsulated properties.

Copy code The code is as follows:

$("#newClassImg").attr("src ", "./images/plus3.jpg");//Change the image source
$("#newClass").css("background-color", "#d6d6d6");//Change the background color

Recommend a Jquery Chinese document query website
