Implementing a gesture animation effect for Android and iOS based on JS_javascript skills

Without further ado, let me show you the renderings first:

This is the effect under iOS, and it is completely the same under Android. Through the do_GestureView component and do_Animation component, deviceone can easily implement complex cross-platform purely native animation effects. This example is to control the up and down animation sliding of the picture through gestures to achieve the opening and closing effect, and also supports sound effects.

The following is the main code

//index.ui.js
var do_Animator1 = mm("do_Animator");
do_Animator1.append(500, {
y: -1334,
curve:"Linear"
});
var do_Animator2 = mm("do_Animator");
do_Animator2.append(500, {
y: 0,
curve:"Linear"
});
do_Page.on("NextPagemoveing", function(){
currentView=json_define[currentIndex].view;
currentIndex++;
if (currentIndex>=json_define.length) currentIndex=0;
nextView=json_define[currentIndex].view;
for(var i=0;i<json_define.length;++i){
if (json_define[i].view != currentView && json_define[i].view != nextView){
json_define[i].view.visible=false;
}
else{
json_define[i].view.visible=true;
}
}
currentView.fire("closingBottom", "NextPagemove");
});
do_Page.on("NextPagemove", function(){
nextView.fire("initMoving", "NextPagemoved");
});
do_Page.on("NextPagemoved", function(){
currentView.y= 0;
nextView.y= 1332;
do_ALayout_main.y=0;
do_ALayout_main.redraw();
do_ALayout_main.animate(do_Animator1, function(){
nextView.fire("opening");
});
});
do_Page.on("PrePagemoveing", function(){
currentView=json_define[currentIndex].view;
currentIndex--;
if (currentIndex<0) currentIndex=json_define.length -1;
nextView=json_define[currentIndex].view;
currentView.fire("closingHead", "PrePagemove");
});
do_Page.on("PrePagemove", function(){
nextView.fire("initMoving", "PrePagemoved"); 
});
do_Page.on("PrePagemoved", function(){
for(var i=0;i<json_define.length;++i){
if (json_define[i].view != currentView && json_define[i].view != nextView){
json_define[i].view.visible=false;
}
else{
json_define[i].view.visible=true;
}
}
currentView.y= 1332;
nextView.y= 0;
do_ALayout_main.y=-1334;
do_ALayout_main.redraw();
do_ALayout_main.animate(do_Animator2, function(){
nextView.fire("opening");
});
});
