This article mainly introduces how to use hover in javascript. It is very detailed and has a certain reference value. Friends who are interested must finish it!

In JavaScript, the hover () method is used to specify the function to run when the mouse pointer hovers over the selected element, either when the pointer is over the element or when the pointer leaves, with the syntax of "$(element) .hover (inFunction,outFunction)".

The operating environment of this tutorial: windows10 system, javascript1.8.5 version, Dell G3 computer.

The hover () method specifies two functions to run when the mouse pointer hovers over the selected element.

Method triggers mouseenter and mouseleave events.

Note: if you specify only one function, both mouseenter and mouseleave execute it.

The syntax is:

$(selector) .hover (inFunction,outFunction)

Call:

(selector) .hover (handlerIn, handlerOut)

It is equivalent to the following ways:

$(selector). Mouseenter (handlerIn). Mouseleave (handlerOut)

Note: if only one function is specified, it will run on the mouseenter and mouseleave events.

Call:

$(selector) .hover (handlerInOut)

Equivalent to:

(selector) .on ("mouseenter mouseleave", handlerInOut)

Examples are as follows:

(document) .ready (function () {$("p") .hover (function () {$("p") .css ("background-color", "yellow");}, function () {$("p") .css ("background-color", "pink");});})

Move the mouse to the paragraph.
