标签: javascript jquery html css iscroll

请帮我用iscroll滚动固定列表项。我正在开发一个项目,我想使用iscroller一次滚动三个LIST项目。我已经尝试使用scrollTo,ScrollToPage,iscroller的ScrollToElement函数滚动,但它对我不起作用所以请帮我滚动固定长度项目一次用户滚动。我正在使用android项目,我正在使用iscroll4来滚动元素。

我的凯德就像这样......

如果我正确地获取它,你想要在iscroll窗口中捕捉每个第3项。

我想不出任何优雅的方法(不确定是否有一个选项允许在捕捉之前设置要忽略的元素数量)

但是你可以(取决于你稍微修改一下标记的灵活性)将这三个元素作为每个“li”的子元素移动。

HTML / CSS / JS。

CSS和JS之间没有太大区别,只是HTML的一些改动

HTML:

<div class="span8 marginleft mid-menu-panel" id="headerWrapper">
<ul id="scroller">
    <li class="menu">
        <div>block 1</div>
        <div class="cf">
            <div class="span3">
                item 1
            </div>
            <div class="span3">
                item 2
            </div>
            <div class="span3">
                item 3
            </div>
        </div>
    </li>
    <li class="menu">
        <div>block 2</div>
        <div class="cf">
            <div class="span3">
                item 4
            </div>
            <div class="span3">
                item 5
            </div>
            <div class="span3">
                item 6
            </div>
        </div>
    </li>
    <li class="menu">
        <div>block 3</div>
        <div class="cf">
            <div class="span3">
                item 7
            </div>
            <div class="span3">
                item 8
            </div>
            <div class="span3">
                item 9
            </div>
        </div>
    </li>
</ul>
</div>

CSS:

.cf {
     overflow:hidden;
}
.span3 {
    float:left;
    height:100px;
    background:green;
    width:210px;
}
.span8{
    position: absolute;
    width:630px;
    height:100px;

}
.menu{
    float:left;
    width:630px; /* same as parent( .span8 ) to make sure only 1 .menu is visible ofc */
    height:100px;
    background-color:red;
}
#scroller{
    width:1890px; /* total width of children, 630 * 3 */
    overflow:hidden;
    list-style:none;
    padding:0;
    margin:0;
}

JS:

        myScroll = new iScroll('headerWrapper',{
            snap: 'li',
            hScrollbar: false,
            vScrollbar: false ,
            momentum: true,
            vScroll: false

        });

希望有所帮助。
