我想送一个浮动变量为ActionScript。

I want to send a float variable to Actionscript.

我用 window.document.setVariable（），但它仅支持键入字符串，而忽略 0 和点（。）

I use window.document.setVariable(), but it only supports type String, and ignores 0 and point (.)

我尝试用 parseFloat（）将和值*在JavaScript 1 ，但它不工作。

I try to use parseFloat() and value * 1 in javascript,but it doesn't work.

推荐答案

您的问题是pretty的模糊。不过，这里有云：

Your question is pretty vague. Still, here goes:

有2（编辑为 3 ）方法来从HTML获取变量到Flash中。两者都使用 ExternalInterface的类

There are 2 (edited to 3) methods to get a variable into Flash from the html. Both use the ExternalInterface class

（1）：变量拉成ActionScript

(1): Pull the variable into ActionScript

//JavaScript:
var myVariable=3.14159; //or whatever you want to set it as

function getMyVariable() {
    return myVariable;
}


//Flash
var myVariable:Number=ExternalInterface.call("getMyVariable");

（2）：把变量转换成ActionScript

(2): Push the variable into ActionScript

//Flash
ExternalInterface.addCallback("pushVar", varPushed);
var myVariable:Number=0;
function varPushed(x:Number):void {
    myVariable=x;
}



//JavaScript
var myVariable=3.14159; //or whatever you want to set it as
var fl = document.getElementById('myflashobject');
fl.pushVar(myVariable);

修改 （3）：使用Flash变量

EDIT (3): Use flashVars

如果你使用SWFObject的，那么您添加使用以下行FlashVars的：

If you use swfObject, then you add flashVars using the following line:

var flashvars = {}; 
    flashvars.myVariable=3.14159
...
...
swfobject.embedSWF( 
    "FlashVarTest.swf", "flashContent", "100%", "100%", swfVersionStr, 
    xiSwfUrlStr, flashvars, params, attributes); 

如果您使用＆LT;对象＆gt; 标记，然后添加Flash变量是这样的：

If you use the <object> tag then you add flashVars like this:

 <object id='mySwf' classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' height='100%' width='100%'>
        <param name='src' value='FlashVarTest.swf'/>
        <param name='flashVars' value='myVariable=3.14159'/>
        <embed name='mySwf' src='FlashVarTest.swf' height='100%' width='100%' flashVars='myVariable=3.14159'/>
    </object>

无论你埋线法的，您可以访问FLASHVARS在AS3中是这样的：

Regardless of your embedding method, you access flashVars in AS3 like this:

如果你正在使用Flex SDK：

If you are using the Flex SDK:

var myVariable:Number = FlexGlobals.topLevelApplication.parameters.myVariable;

如果你不使用Flex SDK：

If you are not using the Flex SDK:

var myVariable:Number =Number(LoaderInfo(this.root.loaderInfo).parameters.myVariable);
