javascript - Cons of MouseOver for webpages -


so creating "button" multiple images within slideshow , whenever mouseover it, image changes image.

however whenever slideshow image changes, mouseover effect gets removed mouseout state since technically mouse no longer on image.

i tried having fade effect button of searches lead using hover functions instead of mouseover , mouseout.

so wondering if hover better mouseover in terms of it's potential capabilities?

is possible pause slideshow event on hover, etc? , how can go doing it?

here current code:

function.js

$(function () {      $('#01 img:gt(0)').hide();     setinterval(function () {         $('#01 :first-child').fadeout(1500)            .next('img').fadein(1500)            .end().appendto('#01');     },       3000); });  $(document).ready(function () {      $("#image1").mouseover(function () {         $(this).attr("src", "images/board_01_over.jpg");     });      $("#image1").mouseout(function () {         $(this).attr("src", "images/board_01_01.jpg");     }); });

main.css

    #board {     float: left;     width: 998px;     overflow: hidden; }   .fadein {      float: left;     position: relative;     width: 240px;     height: 140px;     margin: 1px 1px 1px 1px; }      .fadein img {         position: absolute;         left: 0;         top: 0;         height: 140px;         opacity: 0.6;         overflow: hidden;     }          .fadein img:hover {             opacity: 1;         }

main.html

     <div id="board">          <div class="fadein" id="01">              <img src="images/board_01_01" id="image1" />               <img src="images/board_01_02.jpg" id="image2" />          </div>       </div>

since using jquery can utilize hover() function.

http://api.jquery.com/hover

$("#image1").hover(function () {     $(this).attr("src", "images/board_01_over.jpg"); },  function () {     $(this).attr("src", "images/board_01_01.jpg"); });

for slider it's easier make little object out of it's easier control.

var slideshow = {     interval:null,      start: function () {         ...         initialize         ...         // catch interval id can stop later on         this.interval = window.setinterval(this.next, 3000);     },      next: function () {         /*          * cannot refer keyword in function          * since gets executed outside object's context.          */         ...         logic         ...     },      stop: function () {         window.clearinterval(this.interval);     } };

now can call

slideshow.start(); slideshow.stop();

from anywhere start , stop slider.
