In jquery, there is only one class selector that selects an element with a specified class attribute value and performs various operations on that element; the syntax "$(". The class name ")". The class name (that is, the value of the class attribute) must be preceded by a period ".", otherwise the selector will not take effect.

The operating environment of this tutorial: windows7 system, jquery1.10.2 version, Dell G3 computer.

In jquery, there is only one class selector.

The class selector, also known as the "class selector", is used to select elements that specify the value of the class property.

We can define the same class for "the same element" or "different element", and then perform various operations on the element of the class.

Syntax:

$(". Class name")

The class name (that is, the value of the class attribute) must be prefixed with a full stop, otherwise the selector will not take effect. The class name is preceded by an English full stop to indicate that this is a class selector.

For example:

$(function () {$(".lv") .css ("color", "red");})

$(".lv") .css ("color", "red") indicates that all elements of the class= "lv" are selected, and then define the color of those elements as red.
