其时有2个WebView,一个main是用来装主页面,一个menu是用来装菜单(为提高性能,菜单项是采用了预加载方式的,预加载时为了避免和主页面争夺资源,采用延时加载,例如:
//plusReady事件后,自动创建menu窗口;
mui.plusReady(function() {
main = plus.webview.currentWebview();
//setTimeout的目的是等待窗体动画结束后,再执行create webview操作,避免资源竞争,导致窗口动画不流畅;
setTimeout(function () {
//侧滑菜单默认隐藏,这样可以节省内存;
menu = mui.preload({
id: 'offcanvas-drag-right-plus-menu',
url: 'offcanvas-drag-right-plus-menu.html',
styles: {
left: 0,
width: '70%'
}
});
},300);
});
2. 所谓侧滑,就是控制菜单WebView的显示,使用它的left来定位左边位置;
3. 要打开新的webView,要注意webview的show方法使用:
void plus.webview.show( id_wvobj, aniShow, duration, showedCB, extras );
参数含义:(1)是webview对象 (2)动画效果,从没显示过,一般用"none",(3)动画过渡时间 (4)当指定Webview窗口显示动画执行完毕时触发回调函数,窗口无动画效果(如"none"动画效果)时也会触发此回调。(5)传递的参数;
4.显示的方法:
(1)按钮点击后,让menu直接show出来,并对main设置样式,比如
menu.show("none",0,function(){
main.setStyle({
left:"70%",
transition:{
duration:150
}
});
});
(2)关闭侧滑菜单,实际就是设置main的样式了,比如:
main.setStyle({
left: '0',
transition: {
duration: 150
}
});
另外注意窗体切换完成后要关掉menu
//等窗体动画结束后,隐藏菜单webview,节省资源;
setTimeout(function() {
menu.hide();
}, 200);
5.被打开的WebView的界面如何控制关闭侧滑菜单:
(1)先要找到主页面,main = plus.webview.currentWebview().opener();
(2)激发主页面的某个事件,例如:mui.fire(main,"menu:swipeleft");
给装两个分类的div加上overflow:scroll试试,分类内部的元素float:left
这个可以通过绝对定位,配合left设置 或者translate去实现
left的方法:
比如让class为menu的元素宽为300px,高100%的,设置left为-300px;在这期间可以加一个过渡transition:left 0.3s ...;
然后让class为menu active的元素设置 left设置为0就可以了 ,在这期间可以加一个过渡transition:left 0.3s ...;
然后可以通过Jquery的toggleClass('active');来实现切换
translate
比如让class为menu的元素宽为300px,高100%的,设置left为-300px;在这期间可以加一个过渡transition:left 0.3s ...;
然后让class为menu active的元素设置 transform:translate3d(-300px,0,0) ,在这期间可以加一个过渡transition:left 0.3s ...;
然后可以通过Jquery的toggleClass('active');来实现切换
这个过程中 需要注意 body需要overflow:hidden; (不然会有滚动条,可设置overflow-x即可)
left 和 translate 最好用translate ,translate3d可以开启GPU硬件加速,性能会更好,体验会更流畅
我github有类似小组件样式

希望能解决你的问题
一共有4种侧滑动画特效。这款CSS3菜单的特点是鼠标划过时即可以各种动画方式展开和隐藏菜单项,该动画方式由CSS3中的transition-delay属性来完成
