Help using setMapHTML() please... #6

Closed GoogleCodeExporter closed 9 years ago

What steps will reproduce the problem?
1. Code I am using is pasted below

What is the expected output? What do you see instead?

I see the JavaScript error: 'this.pic.parentNode' is null or not an object

What version of the product are you using? On what operating system?

imgmap2.0beta5 on Windows Server 2003 (server), Windows XP (client)

Please provide any additional information below.

I have successfully set the editor up and I am now trying to use the 
setMapHTML() function (in order to pass in a previously edited image map 
for re-editing), however am having some dificulties. Below is some code 
that I am testing with:

<script>
  var existingMap='<map id="imgmap2008123151556" 
name="imgmap2008123151556"><area shape="rectangle" alt="Page Link" 
title="" coords="183,42,318,209" href="http://news.bbc.co.uk" 
target="_blank" /></map><img src="test.jpg" usemap="#imgmap2008123151556" 
border="0"/>';
  </script>

  <button onclick="javascript:myimgmap.setMapHTML(existingMap)">Set 
Map</button>

I have tried passing in the map code directly but have no joy.

The result of the above (when clicking the button) is in the attached 
image and reads:

'this.pic.parentNode' is null or not an object

The way the page will (hopefully) work is that this will be passed in as 
the above.

ANY assistance you could offer would be gratefully received.

Thanks,

Darren

Hi Darren,

I guess you are missing the pic_container from your imgmap instance setup. Can 
you
paste here your instance setup code?

Hi Adam,

I have it working now. What I found I had to do was intantiate (load) and image 
prior. The below code now works.

Thanks

if (existingMap) {
    myimgmap.loadImage(selectedImage);myimgmap.setMapHTML(existingMap);
}
