目前暴走漫画demo主要做出了5个一级页面。当按下页面下方对应按钮时,按钮颜色改变,并且在do_ViewShower中展示出对应页面(page3则是新打开一个页面)。 一 总体布局
在主页面index中,下方是五个控制页面显示的按钮;上方是do_ViewShower组件,用来存储将要展示的页面,如图index所示。其中do_ViewShower组件与按钮之间的关系对应的代码如下:[mw_shl_code=applescript,true]
//声明四个按钮,在主页中间展示
var button0=ui("do_alayout_4");
var button1=ui("do_alayout_5");
var button2=ui("do_alayout_7");
var button3=ui("do_ALayout_17");
var zhongyang=ui("do_ALayout_18");
var iv0=ui("do_imageview_1");
var iv1=ui("do_imageview_2");
var iv2=ui("do_imageview_4");
var iv3=ui("do_imageview_5");
var buttons = [ button0,button1,button2,button3 ];
var ivs= [iv0,iv1,iv2,iv3];
//中央按钮,按下出现新的一页
zhongyang.on("touchDown",function()
{
zhongyang.source="source://image/anxia.png";
});
zhongyang.on("touch",function()
{
zhongyang.source="source://image/source://image/13.png";
app.openPage("source://view/page3/cell3.ui");
});
var checkFun = function(index) {
for (var i = 0; i < buttons.length; i++) {
if (index == i) { // 表示选中了第几个
ivs.source = "source://image/d" + i + ".png";
} else {
ivs.source = "source://image/s" + i + ".png";
}
}
viewShower.showView("view" + index, "fade", 300);
};
buttons.forEach(function(button, i) {
button.on("touch", function(data, e) {
checkFun(i);
});
});
var viewShower = ui("do_ViewShower_1");
var data = [ {//写数据
"id" : "view0",
"path" : "source://view/page1/cell1.ui"
}, {
"id" : "view1",
"path" : "source://view/page2/cell2.ui"
}, {
"id" : "view2",
"path" : "source://view/page4/cell4.ui"
}, {
"id" : "view3",
"path" : "source://view/page5/cell5.ui"
} ];
viewShower.addViews(data);//绑定数据
viewShower.showView("view1");//确定showvoew最开始显示的页面
//viewShower订阅一个viewChanged事件,当viewShower切换View 时触发
viewShower.on("viewChanged", function(data, e) {
//触发一个自定义事件 indexChanged, 在view0中订阅该事件
// page.fire("indexChanged");
//触发一个带参数的自定义事件,data的值为:View切换后的id
page.fire("indexChanged",data);
});
//翻页
page.on("back",function(){app.closePage()});[/mw_shl_code]
二 page部分
下面是五个页面从左到右的概扩。
(1)page1部分主要使用listview,页面可以下拉刷新,如图 1.png所示。
在listview中使用了三个cell(结构如图11.png),分别对应与标头信息(cell1list1.ui),图片(cell1list2.ui)与结尾(cell1list3.ui)。刷新功能部分,需要首先将listview的ui界面中的isHeaderVisble设置为true。listview使用代码如下所示:[mw_shl_code=javascript,true]var app = sm("do_App");
var page = sm("do_Page");
var nf = sm("do_Notification");
var listview = ui("do_ListView_1");
var list_listdata = mm("do_ListData");
listview.bindItems(list_listdata);
//listview绑定数据,绑定事件,点击触发
list_listdata.addData([
{template:0,"image":"source://image/71.png","name":"indifference","date":"8.24"},
{template:1,"image":"source://image/image1.jpg"},
{template:2,"zan":"123个赞","pinglun":"341个评论","image1":"source://image/51.png","image2":"source://image/52.png","image3":"source://image/53.png"},
{template:0,"image":"source://image/72.png","name":"cross","date":"8.25"},
{template:1,"image":"source://image/image2.jpg"},
{template:2,"zan":"23个赞","pinglun":"123个评论","image1":"source://image/51.png","image2":"source://image/52.png","image3":"source://image/53.png"}
]);
listview.refreshItems();
listview.on("pull", function(data) {
/**
* @此事件将会多次执行.
* @state == 0 : pull动作开始
* @state == 1 : pull动作持续中
* @state == 2 : pull动作结束
*/
if (data.state !== 2) return;
this.rebound();
});[/mw_shl_code]
(2)page2部分的实现比较复杂,使用了listview,segment,slideview三个组件的嵌套循环。
我们首先对三层组件的嵌套进行分解。首先在page5的界面中,我们可以看到使用了一个listview使得界面可以上下滑动。然后在热门收藏对应的这一部分,界面是可以左右滑动的,这是使用了segmentview。最后,每一个可以左右滑动的小框,每隔一定时间又会自动变换图片,这一部分是使用slideview与timer制作。
在写页面时,从外圈向里圈写。 cell2.ui的布局如图221所示,这里只有一个listview,代码如下:
[mw_shl_code=javascript,true]
//获取listview,绑定listdata
var listview = ui("do_ListView_1");
var list_listdata = mm("do_ListData");
listview.bindItems(list_listdata);
//listview绑定数据,绑定事件,点击触发
list_listdata.addData([
{template:0},
{template: 1,"image1":"source://image/16.png","image2":"source://image/17.png"},
{template: 1,"image1":"source://image/18.png","image2":"source://image/19.png"},
{template: 1,"image1":"source://image/110.png","image2":"source://image/111.png"},
{template: 1,"image1":"source://image/112.png","image2":"source://image/113.png"},
{template: 1,"image1":"source://image/114.png","image2":"source://image/115.png"},
{template: 1,"image1":"source://image/116.png","image2":"source://image/117.png"},
{template: 1,"image1":"source://image/118.png","image2":"source://image/119.png"},
{template: 1,"image1":"source://image/120.png","image2":"source://image/121.png"},
{template: 1,"image1":"source://image/122.png","image2":"source://image/123.png"},
{template: 1,"image1":"source://image/124.png","image2":"source://image/125.png"}
]);
listview.refreshItems();
[/mw_shl_code]
在cell2.ui的两个cell(cell2child.ui , cell2child1.ui)中,cell2child1.ui(如图222)是一个最基本的cell,而cell2child.ui中包含了一个segmentview,在cell2child1.ui对应的js文件(cell2child.ui.js)中,对segment进行了数据绑定,代码如下:
[mw_shl_code=javascript,true]var app = sm("do_App");
var page = sm("do_Page");
var nf = sm("do_Notification");
ui("$").setMapping({
});
//获取segmentview,绑定listdata
var SegmentView = ui("do_SegmentView_2");
var SegmentView_listdata = mm("do_ListData");
SegmentView.bindItems(SegmentView_listdata);
//segmentview绑定数据,绑定事件,点击触发
SegmentView_listdata.addData([ {template:0},
{template:1},
{template:2},
{template:3},
{template:4}
]);
SegmentView.refreshItems();
[/mw_shl_code]
我们可以从cell2child.ui.js的代码中看到,segmentview一共绑定了五个cell。在cell2childseg文件中,实现了本嵌套的第三层。在cell2child的模板cell2childseg2.ui,cell2childseg5.ui,cell2childseg6.ui,cell2childseg7.ui,cell2childseg8.ui,中使用了一个slideview组件。我们在cell2childseg2.ui,cell2childseg5.ui,cell2childseg6.ui,cell2childseg7.ui,cell2childseg8.ui,对应的js文件中对slideview的内容进行了绑定,同时加上了定时器,使它们可以自动翻转。这里选取cell2childseg2.ui为例,代码如下:
[mw_shl_code=applescript,true]var app = sm("do_App");
var page = sm("do_Page");
var nf = sm("do_Notification");
ui("$").setMapping({
});
var do_SlideView_1 = ui("do_SlideView_1");
var slide_listdata = mm("do_ListData");
do_SlideView_1.bindItems(slide_listdata);
//listview绑定数据,绑定事件,点击触发
slide_listdata.addData([
{template:0,"text":"总有一种世界是你未曾见过","image":"source://image/q7.jpg"},
{template:1,"text":"总有一种世界是你未曾见过","image":"source://image/q8.jpg"},
{template:2,"text":"总有一种世界是你未曾见过","image":"source://image/q9.jpg"}
]);
do_SlideView_1.refreshItems();
var i=1;
var timer01 = mm("do_Timer");
timer01.delay = 0;
timer01.interval = 1000;
var DURATION01 = 0;
timer01.on("tick", function(){
if(DURATION01 >3){
DURATION01 = 0;
do_SlideView_1.index=i%3;
i++;
}
DURATION01++;
});
timer01.start();
[/mw_shl_code] 最后我们看slideview所绑定的数据,有四个cell,则有四张图片来回改变。slideview的模板直接就是一张图片。这样,我们就完成了三个组件的嵌套使用。
(3)page3部分与其他page不同的是,点击按钮弹出的是一个单独的页面。
当点击中间的按钮时,下图page3显示,当点击page3图片所示的“X”时,页面关闭。代码如下:[mw_shl_code=javascript,true]
var nf = sm("do_Notification");
var app = sm("do_App");
var page = sm("do_Page");
var close=ui("do_ALayout_2");
//翻页
page.on("back",function(){app.closePage()});
close.on("touch",function(){
app.closePage()
});
[/mw_shl_code]
(4)page4比较简单,直接画页面就可以。
(5)page5主要使用listview组件。
代码如下:[mw_shl_code=applescript,true]//related to cell5.ui
var nf = sm("do_Notification");
var app = sm("do_App");
var page = sm("do_Page");
var listview = ui("do_ListView_1");
var list_listdata = mm("do_ListData");
listview.bindItems(list_listdata);
list_listdata.addData([
{template:0}
]);
listview.refreshItems();
[/mw_shl_code]
