Question

All the examples of jQuery.append() seem to take an html string and append it to a container. I have a slightly different use case. My server returns me an XML that contains HTML text to be displayed, something like:

<event source="foo">
    <contents>
        <h1>This is an event</h1>
        This is the body of the event
    </contents>
</event>

I have a div where this content needs to be displayed.

My JS currently does the following:

1. Loads up the XML data into jQuery in the $.ajax() success handler:

   var jData = $( data );

2. Find the contents tag and tries to add its children to the div that is supposed to display the event:

   var contents = jData.find( "contents" );
   if( contents != null )
   {
       $( contents ).children().each( function( index, value ) 
       {
        $( "#eventDiv" ).append( $( value ) );
       });
   }
   

The append() call fails with Uncaught Error: WRONG_DOCUMENT_ERR: DOM Exception 4 on Chrome. The debugger shows value to be a DOM Element object and $( value ) to be an Object that contains the Element.

Any help will be appreciated.

Thanks.

You can’t append nodes that belong to one DOM tree to another document.

Try to clone them:

$("#eventDiv").append( jData.find("contents").children().clone() );

or simply use their textual representation to have them re-created:

$("#eventDiv").append( jData.find("contents").html() );
