今天,我完成了一项工作,应该在对话框内显示Flash Player。我能够很轻松地做到这一点。但是我的Flash Player包含一个文本框,一旦将Flash Player加载到对话框中,该文本框就需要聚焦,但是默认情况下它不会聚焦。有人可以帮我解决这个问题吗?
但是,如果我们在Flash Player中单击,则可以获取焦点,但默认情况下无法。
我会告诉你我到目前为止所做的

以下代码用于将焦点放在Flash对象上
setTimeout(setFocusToFlash(), 2000);
最佳答案
首先:swfobject.embedSWF(...)
将需要几毫秒的时间将swf嵌入HTML。因此,您不能立即调用$('#flashApp').tabIndex=0;
或$('#flashApp').focus();
第二:您确定$('#flashApp')
返回什么。
第三:setTimeout(setFocusToFlash(), 2000);
是错误的。它将立即调用该函数。正确的是setTimeout(setFocusToFlash, 2000);
固定以下三个步骤,以查看下面的操作方法。
首先声明这样的功能。这就是在Firefox中起作用的方法。
function setFocusToFlash() {
document["flashApp"].tabIndex=0;
document["flashApp"].focus();
}
如果不起作用,
window["flashApp"].focus();
应该在其他浏览器中起作用。并使用embedSWF中的ready回调,如下所示
swfobject.embedSWF(
"testFocusProject.swf", "flashContent",
"840px", "500px",
swfVersionStr, xiSwfUrlStr,
flashvars, params, attributes, function(){
setTimeout(setFocusToFlash, 500);
});
500毫秒足以让我获得焦点。您可以测试并设置所需的延迟。
