1、點選選中設定樣式

1 //預設選中第一個
2 $('.navigation>a:first-child>div').addClass('category-selected');
3 //選中樣式切換
4 $('.navigation>a>div').click((e => {
5     $('.navigation a>div').removeClass('category-selected');
6     $(e.target).addClass('category-selected');
7 }));

2、onmouseover和onmouseout事件

• img標籤

 1 /**
 2  * 滑鼠懸浮
 3  * @param id
 4  * @param imgOver
 5  */
 6 function setFootImgOver(id, imgOver) {
 7     $("#footImgLogo" + id).attr('src', imgOver);
 8 }
 9 
10 /**
11  * 滑鼠移除
12  * @param id
13  * @param imgOut
14  */
15 function setFootImgOut(id, imgOut) {
16     $("#footImgLogo" + id).attr('src', imgOut);
 
17 }

• backgroud-image標籤

 5  */
 6 function proCategoryImgOver(id, imgOver) {
 7     $("#proCategoryImg" + id).css({'background-image': 
 8          'url(' + imgOver + ')'});
 9 }
10 
11 /**

13  * @param id
14  * @param imgOut
15  */
16 function
 
 proCategoryImgOut(id, imgOut) {
17     $("#proCategoryImg" + id).css({'background-image':
