How to assign dynamic value to <param > tage

I need to pass a dynamic value to a object in a HTML, which is something like:

<html lang="en">
<head>
...
<SCRIPT language='JavaScript' charset='utf-8'>  </SCRIPT>
</head>
...

<object id="myObj" type="...." ....>
<param name='myVars' value='initVar="+init+"'; />
</object>
...

</html>

The init value 12345 was not passed, in stead " init " was passed. What did I do wrong?

Hi Matt,

You can use body onload attribute to load the value.
You can refer the following piece of code.

<html>
<head>
<script>
var paramValue = 1234;
function setTextBoxValue(){
document.getElementById("textBox1").value=paramValue;
}
</script>
</head>
<body onload="setTextBoxValue()">
<input type="text" id="textBox1"/>

</body>
</html>

You really should be doing it with a serverside language if it requires no input from the user or the browser.

you probably want to use DOM methods or document.write.

The original data is Form input and a Javascript is called with a onclick event to process the input. The init variable is a result of processing.

Eric, Could you help me with this?

Bear, Valli:

I tried the code below:


<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>My Portfolio</title>
<SCRIPT language='JavaScript' charset='utf-8'>  </SCRIPT>
</head>

<body scroll="yes">

<table>
<tr>
<td>
<div style="width:192px;height:310px;border:1px solid rgb(0, 0, 0);">
<table border="0">
<tr>
<td >
You may enter your own symbol and shares with correct format (e.g., IBM:100)
</td>
</tr>
<tr>
<td >
<textarea id="quoteShare" style="width:186px;font-weight:bold;font-size:11px;" rows="13" >
YHOO:200
JAVA:123
</textarea>
</td>
</tr>
<tr>
<td>
<button onclick="callInit()" type="button" style="color:#242F6D;font-weight:bold;font-size:10px;">Get Values of My Portfolio</button>
</td>
</tr>
</table>
</div>
<td>
<td>
<table border="0" >
<tr >
<td >
<object id="myPortfolio" type="application/x-shockwave-flash" data="MyPortfolio.swf" WIDTH="850" HEIGHT="460" >
<param id='param1' name='movie' value='MyPortfolio.swf'/>
<embed id='embed1' name='myPortfolio' src='MyPortfolio.swf' pluginspage='http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash' height='460' width='850'/>
</object>
</td>
</tr>
</table>
<td>
</tr>
</table>
</body>
</html>

The variable "quoteShare" was not passed to the swf object.

It probably did not change since it is not reading the value after you change it. Sounds like you need to use createElement or innerHTML and replace the object tag on the page when you have the info.

Eric

I tried something like:

function callInit() {
var paramElement = document.createElement("param");
paramElement.setAttribute("id", "flash");
paramElement.setAttribute("name", "flashVars");
paramElement.setAttribute("value", "quoteShare=JAVA:3322");;

var objElement = document.getElementById("myPortfolio");
objElement.appendChild(paramElement);

var myElement = document.getElementById("flash");
alert(myElement.value); //It shows the value correctly
}

...

<object id="myPortfolio" type="application/x-shockwave-flash" data="MyPortfolio.swf" WIDTH="850" HEIGHT="460" >
<param name='movie' value='MyPortfolio.swf'/>
<embed name='myPortfolio' src='MyPortfolio.swf' pluginspage='http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash' height='460' width='850'/>
</object>

The swf object was called, but the param "flashVars" was not passed with the call.
If I just add the element <param name='flashVars' value='quoteShare=JAVA:123' /> within <object>, the 'flashVars' variable will be passed.

Please be sure to use code tags when posting code to the forums. Unformatted code is extremely hard to read and many people that might be able to help you will just move along to posts that are easier to read. Please read this for more information.

I did some more testing on the <object > of swf and <param> for the flashVars. It seems that the swf <object> loaded the <param > elements
within it and kept using the initial <param > even though the <param> elements are updated or new <param > elements are added later.

Create the entire object, not just the parameter.

Eric

Is there a way to reload the <object > with an event?
