问题描述
我使用的Flash文本字段控件来显示内部闪存presentation一些HTML内容在一个大的触摸屏售货亭中显示。不幸的是,如果在所显示的HTML内容指向一个不存在的图像中的任何图像标记,一个对话被示出具有错误消息
错误#2044:未处理IOErrorEvent :.文本=错误#2035:找不到网址。
我试图避免这种对话弹出。该解决方案通过加载器类加载的内容是赶上IOErrorEvent.IO_ERROR ,但我试过监听,关于文本字段,在舞台上,主要和的LoaderInfo无济于事。我已经试过包装整个事情在一个try-catch,而且也不能正常工作。
下面是简化的code我使用的是找到解决办法:
包{
进口flash.display.Sprite;
进口flash.errors.IOError;
进口对象类型:flash.events.Event;
进口flash.events.IOErrorEvent在;
进口API元素flash.text.TextField;
进口flash.text.TextFieldType;
公共类主要扩展Sprite {
公共函数main():无效{
如果(阶段)的init();
其他的addEventListener(Event.ADDED_TO_STAGE,INIT);
}
私有函数初始化(E:事件= NULL):无效{
removeEventListener(Event.ADDED_TO_STAGE,INIT);
VAR HTML:文本字段=新的TextField();
html.type = TextFieldType.DYNAMIC;
html.multiline = TRUE;
html.htmlText =伪造的图像:其中,IMG SRC = \foo.jpg \/>中;
的addChild(HTML);
}
}
}
编辑:这里是整个工作code
。当然有关动态内容等等,则需要图像的列表和一个函数生成处理程序等。
包{
进口flash.display.Loader;
进口flash.display.Sprite;
进口flash.errors.IOError;
进口对象类型:flash.events.Event;
进口flash.events.IOErrorEvent在;
进口API元素flash.text.TextField;
进口flash.text.TextFieldType;
公共类主要扩展Sprite {
公共函数main():无效{
如果(阶段)的init();
其他的addEventListener(Event.ADDED_TO_STAGE,INIT);
}
私有函数初始化(E:事件= NULL):无效{
removeEventListener(Event.ADDED_TO_STAGE,INIT);
VAR HTML:文本字段=新的TextField();
html.type = TextFieldType.DYNAMIC;
html.multiline = TRUE;
html.htmlText =伪造的图像:其中,IMG ID = \图像\SRC = \foo.jpg \/>中;
VAR装载机:装载机= html.getImageReference(图像)作为加载程序;
如果(装载机){
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,功能(五:事件):无效{
跟踪(错误加载foo.jpg!);
});
}
的addChild(HTML);
}
}
}
您可以添加的ID将图像
html.htmlText =伪造的图像:其中,IMG SRC = \foo.jpg \ID =形象/>中;
然后设置IOErrorEvent处理程序,在HTML中每个图像
VAR装载机:装载机= html.getImageReference(图像)作为加载程序;
如果(装载机){
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,功能(五:事件):无效{});
}
I'm using a Flash TextField control to display some HTML content inside a Flash presentation to be shown on a large touch-screen kiosk. Unfortunately, if any image tag in the displayed HTML content points to a non-existent image, a dialogue is shown with the error message
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
I am trying to avoid having that dialogue pop up. The solution for loading content through a loader class is to catch IOErrorEvent.IO_ERROR, but I've tried listening for that on the TextField, on stage, Main and loaderInfo to no avail. I've tried wrapping the whole thing in a try-catch, and that also doesn't work.
Here's the simplified code I'm using to find solutions:
package {
import flash.display.Sprite;
import flash.errors.IOError;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.text.TextField;
import flash.text.TextFieldType;
public class Main extends Sprite {
public function Main():void {
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
var html:TextField = new TextField();
html.type = TextFieldType.DYNAMIC;
html.multiline = true;
html.htmlText = "Bogus image: <img src=\"foo.jpg\" />";
addChild(html);
}
}
}
Edit: And here's the entire working code.
For dynamic content and so forth, of course, you would need a list of images and a function to generate handlers, etc.
package {
import flash.display.Loader;
import flash.display.Sprite;
import flash.errors.IOError;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.text.TextField;
import flash.text.TextFieldType;
public class Main extends Sprite {
public function Main():void {
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
var html:TextField = new TextField();
html.type = TextFieldType.DYNAMIC;
html.multiline = true;
html.htmlText = "Bogus image: <img id=\"image\" src=\"foo.jpg\" />";
var loader:Loader = html.getImageReference("image") as Loader;
if(loader){
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, function(e:Event):void {
trace("Error loading foo.jpg!");
});
}
addChild(html);
}
}
}
You can add ID's to images
html.htmlText = "Bogus image: <img src=\"foo.jpg\" id="image" />";
And then setup IOErrorEvent handler to each image in HTML
var loader:Loader = html.getImageReference("image") as Loader;
if(loader){
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, function(e:Event):void{});
}
