我试图确定用户是否放大了他们的网页,看起来有一些属性可用于帮助确定其中一个属于舞台。browserZoomFactor。我没有尝试过改变价值。它总是1
。
以下是我使用的代码:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

applicationComplete="application1_applicationCompleteHandler(event)">
<fx:Script>
<![CDATA[

var clientWidth:int;
var scaleFactor:Number
if (ExternalInterface.available) {
ExternalInterface.marshallExceptions = true;
clientWidth = ExternalInterface.call(string, ExternalInterface.objectID);
scaleFactor = Number(Number(stage.stageWidth/clientWidth).toFixed(1));
}
zoomFactorLabel.text = "";
zoomFactorLabel.text += "Client width: "+clientWidth + "\n";
zoomFactorLabel.text += "Stage width: "+stage.stageWidth + "\n";
zoomFactorLabel.text += "Calculated Scale factor: "+scaleFactor + "\n";

zoomFactorLabel.text = "Zoom changed";

我还在HTML包装页面中将browserzoom设置为scale和noscale。这两种选择似乎都没有做任何事情。默认情况下应启用浏览器缩放。
如果我手动获取swf对象的客户端宽度,我可以将它与舞台宽度进行比较并获得比例因子,但在Firefox中不起作用(在Mac上)它可以在Safari上运行(在Mac上)。
更新
以下是我在Safari和Mac上看到的内容的截图:
Safari(clientWidth值在缩放时更改)
Firefox(没有找到更改变焦值的值)
答案 0 :(得分:0)
你是否试图在用户ctrl + MouseWheeled html页面后获得swf的大小?如果您缩放整个页面,我认为clientWidth不会改变。你试过window.devicePixelRatio吗?
我也很难确定页面的大小,而这似乎只是在缩放页面时会发生变化的属性
window.onbeforeunload = function(){
var input19 = $('#input19').val();
createCookie(input19,'your-site-cookie',7);
};
window.onload = function(){
var inputx = readCookie('your-site-cookie');
if (inputx) {
$('#input19').attr("value", inputx);
}
};
function createCookie(name,value,days) {
var expires = "";
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days*24*60*60*1000));
expires = "; expires=" + date.toUTCString();
}
document.cookie = name + "=" + value + expires + "; path=/";
}
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
此外,您可能希望获得scrollWidth/Height而不是clientWidth / Height
