Viewport resizing within an iFrame
I'm trying to create a Carrousel in Sencha which displays iframes.
The basic idea is that I have a bunch of HTML files already configured to be viewed on an iPad. So the files have a viewport and everything configured. I created a simple carrousel like this :var rootPanel;
Ext.setup({
onReady: function() {
rootPanel = new Ext.Carousel({
fullscreen: true,
layout: 'card',
items: [
{ html: '<iframe src="http://localhost/file1.html">' },
{ html: '<iframe src="http://localhost/file2.html">' },
{ html: '<iframe src="http://localhost/file3.html">' },
]
});
}
});
The HTML files themselves look like this :
<!DOCTYPE html>
<html>
<head>
<title>Untitled Page</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta name="viewport" content="width=device-width; initial-scale=0.5; minimum-scale=0.5; maximum-scale=1.0;user-scalable=no">
</head>
<body>
<div id="container">
<div style="margin:0;padding:0;position:absolute;left:0px;top:0px;width: 1536px; height: 2048px;text-align:left;z-index:0;">
<img src="image.jpg" style="width: 1536px; height: 2048px;"></div>

</html>
The system sort of works, except that the viewport is not respected and the inside of the iframe is not zoomed out like it's supposed to be. Any idea ?
I'm not familiar with sencha, but iframes don't have the ability to set height to a percentage (100%). So if sencha is setting the width and height to 100%, it won't expand vertically, but should fill the parent horizontally.
Is this what you see?
Try setting the iframe's height manually to a large enough size in px. If you have control of the iframe's content, then you can add a bit of javascript to communicate with the parent and tell it to resize appropriately.
Set 100% on iframe and inner html
var rootPanel;
Ext.setup({
onReady: function() {
rootPanel = new Ext.Carousel({
fullscreen: true,
layout: 'card',
cls: 'some-cards',
items: [
{ html: '<iframe width="100%" height="100%" src="http://localhost/file1.html">' },
{ html: '<iframe width="100%" height="100%" src="http://localhost/file2.html">' },
{ html: '<iframe width="100%" height="100%" src="http://localhost/file3.html">' },
]
});
}
});
And you css be link something like this.
.some-cards .x-innerhtml {
height: 100%;
}
加载中,请稍侯......
