Remarks

The param element is valid within the applet, embed, and object elements.

Note Properties set by a param element cannot be altered by changing the param object.

After the applet, embed, or object element is instantiated, the property set by the param element cannot be changed with the param object. To change the object's properties, use the script properties exposed by the object.

Examples

This example displays the a Windows Store app using JavaScript Data Binding component's outerHTML so you can view the properties assigned by the param elements. You can perform this check to gather information when debugging an object element's properties. You cannot edit the object's outerHTML property without reinitializing the outerHTML object.



// The OBJECT CLASSID below is for the 
// Microsoft Internet Explorer Data Binding component 
// Use just the following HTML and press the button

<object id="tdcContents" classid="clsid:333C7BC4-460F-11D0-BC04-0080C7055A83">
  <param name="DataURL" value="DataBinding.csv">
</object>
<button onclick="oTxt.value=tdcContents.outerHTML">Show Object outerHTML</button><br />

<textarea id="oTxt" style="height: 400; width: 450; padding: 3; overflow=auto;"> </textarea> 

//When the button is pressed the complete list of the object's 
// PARAM elements display unformatted in the TEXTAREA as follows:

<object id="tdcContents" classid="clsid:333C7BC4-460F-11D0-BC04-0080C7055A83">
