Match a div element with the class attribute, the value starts with aaa, and then find its name according to this.

It becomes:

$(".[aaa]”)

I haven't tried. You can refer to the attached information:

Basic selectors (3 types):

$ ("tag name"), such as $ ("p") means that all p tag nodes are selected.

$("#id name "), for example, $("#test") is a label node, and its ID is test.

$ (".Class name"), such as $ (". Test ") is to select all label nodes with test classes.

The $ ("tagname") and $ ("above. Class name ") returns all satisfactory nodes. As for further filtering, some functions can be added, such as eq, gt, lt and so on.

*: Match all elements
