[英]Sencha Touch carousel Image issue
问题描述
I have create a vbox layout view and added carousel images in that as follows: 
我创建了一个vbox布局视图，并在其中添加了轮播图片，如下所示：
var imgSlider1 = Ext.create('Ext.carousel.Carousel',{
direction: 'horizontal',
singleton: true,
height:300,
width:250,
id: 'imgSlider',
bufferSize: 2,
defaults: {
styleHtmlContent: true
},
items: [
{
xtype: 'image',
cls: 'my-carousel-item-img',
src: 'resources/images/training.jpg'
},
{
xtype: 'image',
cls: 'my-carousel-item-img',
src: 'resources/images/upcoming_programms.jpg'
}
]
});
Ext.define('RasovaiApp.view.HomePage',{
extend: 'Ext.Container',
fullscreen: true,
requires:[
imgSlider1
],
config:{
scrollable: true,
layout: {
type: 'vbox'
},
items: [
{
xtype: 'container',
layout: {
height: 300,
type: 'hbox'
},
items: [
{
xtype: 'panel',
height:300,
width:50,
html: '<html xmlns="http://www.w3.org/1999/xhtml">'+
'<head>'+
'</head>'+
'<body>'+
'<img src="resources/images/arrow_left.png" alt="Previous" width="30" height="60" align="left" onclick="'+'Ext.getCmp(\'imgSlider\').previous();console.log(\'previous\')'+'"/>'+
'</body>'+
'</html>'
},
Ext.getCmp('imgSlider'),
{
xtype: 'panel',
height:300,
width:50,
html: '<html xmlns="http://www.w3.org/1999/xhtml">'+
'<head>'+
'</head>'+
'<body>'+
'<img src="resources/images/arrow_right.png" alt="Next" width="30" height="60" align="right" onclick="'+'Ext.getCmp(\'imgSlider\').next();console.log(\'next\')'+'"/>'+

}
});
I have added above view to the viewport in app.js as: Ext.Viewport.add(Ext.create('RasovaiApp.view.HomePage')); 我已将上述视图添加到app.js中的视口中，如下所示：Ext.Viewport.add（Ext.create（'RasovaiApp.view.HomePage'））; The thing is when I run the above code it runs perfectly fine with on the desktop browser, but when i build the application and run it on desktop browser, it only shows one carousel image with two radio button. 问题是，当我运行上面的代码时，它可以在桌面浏览器上完美运行，但是当我构建应用程序并在桌面浏览器上运行它时，它仅显示一个带有两个单选按钮的轮播图片。 And when i package the same application for android mobile device and runs on it, then it doesnot show an any of the image, but it shows two radio buttons which indicates it is loading two items in the carousel. 当我为android移动设备打包相同的应用程序并在其上运行时，它不会显示任何图像，但是会显示两个单选按钮，表明它正在轮播中加载两个项目。
I think the problem is with the var imgSlider1 or carousel instance. 我认为问题出在var imgSlider1或轮播实例。 Can any one help me? 谁能帮我？ Any help would be greatful. 任何帮助将是巨大的。

Okay, first thing first, you must not use onClick attribute on HTML element, instead you should bind events to element when required. 好的，首先，您不得在HTML元素上使用onClick属性，而应在需要时将事件绑定到元素。 So check my code to see how to bind tap event to an image. 因此，请检查我的代码以查看如何将tap事件绑定到图像。
Secondly I was asking to put carousel code inside view like this: 其次，我要求将轮播代码放入这样的视图中：
Ext.define('RasovaiApp.view.HomePage',{
extend: 'Ext.Container',
fullscreen: true,
config:{
scrollable: true,
layout: {
type: 'vbox'
},
items: [
{
xtype: 'container',
layout: {
height: 300,
type: 'hbox'
},
items: [
{
xtype: 'panel',
height:300,
width:50,
items: [{
xtype:'image',
src: 'resources/images/arrow_left.png',
height:300,
width:50,
listeners: {
tap : function(me, evt){
console.log("Tap on left");
Ext.getCmp("imgSlider").previous();
}
}
}]
},
{
xtype : 'carousel',
direction: 'horizontal',
singleton: true,
height:300,
width:250,
id: 'imgSlider',
bufferSize: 2,
defaults: {
styleHtmlContent: true
},
items: [
{
xtype: 'image',
cls: 'my-carousel-item-img',
src: 'resources/images/training.jpg'
},
{
xtype: 'image',
cls: 'my-carousel-item-img',
src: 'resources/images/upcoming_programms.jpg'
}
]
},
{
xtype: 'panel',
height:300,
width:50,
items: [{
xtype:'image',
src: 'resources/images/arrow_right.png',
height:300,
width:50,
listeners: {
tap : function(me, evt){
console.log("Tap on right");
Ext.getCmp("imgSlider").next();
}
}
}]
}
]
},
{
xtype: 'panel',
html: '<html xmlns="http://www.w3.org/1999/xhtml">'+
'<head>'+
'<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />'+
'<title>Home</title>'+
'<h1 align="center">Home</h1>'+
'</head>'+
'</html>'
},
{
xtype: 'panel',
html: '<html xmlns="http://www.w3.org/1999/xhtml">'+
'<head>'+
'<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />'+

]
}
});
You can use id attribute of carousel to fetch and invoke method on it. 您可以使用轮播的id属性来获取并调用其上的方法。 I can see you are putting whole forms in panel as HTML, that is also not right approach, Sencha has Form component you should use it. 我可以看到您将整个表单作为HTML放置在面板中，这也不是正确的方法，Sencha具有Form组件，您应该使用它。
