如何确保＆＃34; document.body.appendChild（flash_object）＆＃34;在下一行之前加载？

Question

在调用foo（）之前，有什么方法可以确保加载Flash进程？

window.onload = function (){
    document.body.appendChild(CreateFlashObject("flash_obj"));
    foo();
}
function CreateFlashObject(objectName){
    var obj = document.createElement("object");
    obj.setAttribute("id", objectName);
    obj.setAttribute("type", "application/x-shockwave-flash");
}
function foo(){
    //doing something with the flash_obj
}

您可以将新创建​​的html元素传递给foo函数。它甚至不需要加载你来进行更改。

＆＃13;

window.onload = function (){
    var obj = CreateObject("foo_obj1");
    var obj2 = CreateObject("foo_obj2");
    document.body.appendChild(obj);
    boo();
    foo(obj2);
    document.body.appendChild(obj2);
    console.log(obj,obj2);
}
function CreateObject(objectName){
    var obj = document.createElement("object");
    obj.setAttribute("id", objectName);
    return obj;
}
function foo(obj){
    obj.width = 400;
    obj.height = 400;
}
function boo() {
    var obj = document.getElementById("foo_obj1");
    obj.width = 200;
    obj.height = 200;
}
