android 平臺上(已經試過 nexus 5 , samsung s6等三個機型)，如果先點擊右邊的圖標打開預加載好的webview, 順利滑出；但是不管之后還是之前，如果打開過左邊的webview(drawer 效果)之后，再點擊右邊圖標想打開右邊的webview,就完全打不開，主窗口也沒有移動，只出現了一個半透明的mask,但是 左邊的窗口和drawer效果，毫無影響，從頭到尾都可以順利彈出。請幫我看看是什么問題？代碼見下：

var leftDrawer=null,rightDrawer=null,rootWindow=null;

var leftDrawerStatus=false, rightDrawerStatus=false;

var isLeftInTransition=false,isRightInTransition=false;

mui.plusReady(function(){

plus.screen.lockOrientation('portrait-primary');

rootWindow=plus.webview.currentWebview();

rootWindow.addEventListener('maskClick',function(){

if(leftDrawerStatus){

closeLeftDrawer();

}

else{

closeRightDrawer();

}

});

setTimeout(function(){

leftDrawer=mui.preload({

id:'leftDrawer',

url:'leftDrawer.html',

styles:{

left:0,

top:0,

width:'70%',

zindex:-1

},

show:{

aniShow:'none'

}

});

rightDrawer=mui.preload({

id:'rightDrawer',

url:'rightDrawer.html',

styles:{

right:0,

top:0,

width:'70%',

zindex:-1

},

show:{

aniShow:'none'

}

});

},200);

function openLeftDrawer(){

if(isLeftInTransition){

return ;

}

if(!leftDrawerStatus){

isLeftIntransition=true;

leftDrawer.setStyle({

mask: 'rgba(0,0,0,0)'

});

leftDrawer.show('none', 0, function() {

rootWindow.setStyle({

mask: 'rgba(0,0,0,0.4)',

left: '70%',

transition: {

duration: 150

}

});

mui.later(function() {

isLeftInTransition = false;

leftDrawer.setStyle({

mask: "none"

});

}, 160);

leftDrawerStatus = true;

});

}

};

function openRightDrawer(){

if(isRightInTransition){

return ;

}

if(!rightDrawerStatus){

isRightInTransition=true;

rightDrawer.setStyle({

mask: 'rgba(0,0,0,0)'

});

rightDrawer.show('none', 0, function() {

rootWindow.setStyle({

mask: 'rgba(0,0,0,0.4)',

right: '70%',

transition: {

duration: 150

}

});

mui.later(function() {

isRightInTransition = false;

rightDrawer.setStyle({

mask: "none"

});

}, 160);

rightDrawerStatus = true;

});

}

};

function closeLeftDrawer() {

if (isLeftInTransition) {

return;

}

if (leftDrawerStatus) {

isLeftInTransition = true;

rootWindow.setStyle({

mask: 'none',

left: 0,

transition: {

duration: 200

}

});

leftDrawerStatus = false;

mui.later(function() {

isLeftInTransition = false;

leftDrawer.hide();

}, 300);

}

};

function closeRightDrawer() {

if (isRightInTransition) {

return;

}

if (rightDrawerStatus) {

isRightInTransition = true;

rootWindow.setStyle({

mask: 'none',

right: 0,

transition: {

duration: 200

}

});

rightDrawerStatus = false;

mui.later(function() {

isRightInTransition = false;

rightDrawer.hide();

}, 300);

}

};

document.querySelector('#leftDrawer').addEventListener('tap',function(e){

if(leftDrawerStatus){

closeLeftDrawer();

}

else{

openLeftDrawer();

}

});

document.querySelector('#rightDrawer').addEventListener('tap',function(e){

if(rightDrawerStatus){

closeRightDrawer();

}

else{

openRightDrawer();

}

});

});
