MVC Sencha Touch 无法正确显示选项卡面板
我正在构建一个 MVC Sencha Touch 应用程序,但在使 TabPanel 正常运行时遇到一些问题。问题是这样的,当我有这样的 PosViewport.js 时,一切正常:
touch.views.PosViewport = new Ext.extend(Ext.TabPanel, {
initComponent: function () {
console.log("inside initComponent() of PosViewport.js");
touch.views.PosViewport.superclass.initComponent.call(this);
},
tabBar: {
dock: 'bottom',
layout: {
pack: 'center'
}
},
layout: 'fit',
scroll: 'vertical',
items: [
{
title: 'Reciepts',
iconCls: 'bookmarks',
html: 'one'
},
{
title: 'POS',
iconCls: 'Favorites',
html: 'two'
}
]
});
这里,一切都很棒! 标签栏显示在底部,它适合完美,我可以毫无问题地在两者之间来回切换。
但是,我们不要将这些面板保留在 PosViewport.js 文件中,而是将它们移至两个单独的文件中:
View1.js:
touch.views.View1 = new Ext.extend(Ext.Panel, {
initComponent: function () {
touch.views.View1.superclass.initComponent.call(this);
},
layout: 'fit',
scroll: 'vertical',
fullscreen : true,
title: 'Reciepts',
iconCls: 'bookmarks',
html: 'panel one'
});
和 View2.js:
touch.views.View2 = new Ext.extend(Ext.Panel, {
initComponent: function () {
touch.views.View2.superclass.initComponent.call(this);
},
layout: 'fit',
scroll: 'vertical',
fullscreen : true,
title: '2',
iconCls: 'bookmarks',
html: 'panel two'
});
我将这两个新视图添加到我的 index.html 中。现在,我更新 PosViewport.js 以指向新视图:
touch.views.PosViewport = new Ext.extend(Ext.TabPanel, {
initComponent: function () {
console.log("inside initComponent() of PosViewport.js");
touch.views.PosViewport.superclass.initComponent.call(this);
},
tabBar: {
dock: 'bottom',
layout: {
pack: 'center'
}
},
layout: 'fit',
scroll: 'vertical',
items: [ touch.views.View1, touch.views.View2]
});
一切都完蛋了。底部选项卡栏不可见,因为页面上仅可见顶部的一小部分。面板根本不显示,我根本看不到它们的 HTML 内容。
这是怎么回事?我完全不知道为什么它会这样。非常感谢任何正确方向的指点,谢谢!
I have a MVC Sencha Touch application I'm building and am having some issues getting the TabPanel to function correctly. The issue is this, when I have my PosViewport.js like this, everything works fine:
touch.views.PosViewport = new Ext.extend(Ext.TabPanel, {
initComponent: function () {
console.log("inside initComponent() of PosViewport.js");
touch.views.PosViewport.superclass.initComponent.call(this);
},
tabBar: {
dock: 'bottom',
layout: {
pack: 'center'
}
},
layout: 'fit',
scroll: 'vertical',
items: [
{
title: 'Reciepts',
iconCls: 'bookmarks',
html: 'one'
},
{
title: 'POS',
iconCls: 'Favorites',
html: 'two'
}
]
});
Here, everything is great! The tab bar shows up on the bottom, it fits perfectly, and I can switch back and forth between the two with no problems.
However, instead of keeping those panels inside my PosViewport.js file, let's move them out to two seperate files:
View1.js:
touch.views.View1 = new Ext.extend(Ext.Panel, {
initComponent: function () {
touch.views.View1.superclass.initComponent.call(this);
},
layout: 'fit',
scroll: 'vertical',
fullscreen : true,
title: 'Reciepts',
iconCls: 'bookmarks',
html: 'panel one'
});
and View2.js:
touch.views.View2 = new Ext.extend(Ext.Panel, {
initComponent: function () {
touch.views.View2.superclass.initComponent.call(this);
},
layout: 'fit',
scroll: 'vertical',
fullscreen : true,
title: '2',
iconCls: 'bookmarks',
html: 'panel two'
});
I add both new views to my index.html. Now, I update my PosViewport.js to point to the new views:
touch.views.PosViewport = new Ext.extend(Ext.TabPanel, {
initComponent: function () {
console.log("inside initComponent() of PosViewport.js");
touch.views.PosViewport.superclass.initComponent.call(this);
},
tabBar: {
dock: 'bottom',
layout: {
pack: 'center'
}
},
layout: 'fit',
scroll: 'vertical',
items: [ touch.views.View1, touch.views.View2]
});
And it all goes to hell. The Bottom Tab Bar is not visible, as only a tiny piece of the top is visible on the page. The panels do not show up at all, I cannot see their HTML content at all.
What is going on here? I have absolutely no idea why it is behaving like this. Any pointers in the right direction are much appreciated, thank you!

在第二种情况下,您通过以下方式创建了两个类:
而您需要这些面板的两个实例。因此,添加如下项目:
现在应该可以了。并从这些面板中删除
fullscreen:true
选项。全屏
意味着,它将使面板占据整个视口区域。In the second case you created two classes by this:
whereas you needed two instances of these panels. So, add the items like this:
This should work now. And remove the
fullscreen:true
option from these panels.fullscreen
means, it will make the panels take whole viewport area.
