54636 2011-02-17 04:48:04 -0800 Area element doesn't update region when dynamically altered 2011-05-17 12:26:29 -0700 1 1 1 Unclassified WebKit Images 528+ (Nightly build) All All RESOLVED FIXED HTML5 P2 Normal --- 1 bz kling kling xavi.rmz oldest_to_newest 352757 0 bz 2011-02-17 04:48:04 -0800 If you create an image map with an area, and then you change the coordinates for that area after you have moved the mouse over it, then the area will not update to the new coordinates. In the following example, there is a single area to the left of the image. If you click on it, the area should move to the right, but it doesn't. <img ismap usemap="#map1" style="width:200; height:100"/> <map name="map1"> <area id="area1" shape="rect" coords="0,0,100,100" href="#" title="xx"/ onclick="document.getElementById ('area1').coords = '100,0,200,100'"> </map> I believe the bug lies in HTMLAreaElement.cpp in the mapMouseEvent() function. It only recreates the region for the area if the associated image size changes. If I resize the image as in the code below, then it works. <img id="image1" ismap usemap="#map1" style="width:200; height:100"/> <map name="map1"> <area id="area1" shape="rect" coords="0,0,100,100" href="#" title="xx"/ onclick="document.getElementById ('area1').coords = '100,0,200,100'; document.getElementById ('image1').style.width = 201"> </map> The code needs changing to recalculate the region when the shape type or coordinates of the area have changed since the last call. i.e. add a recalculate flag that gets set when either of these attributes change. 364440 1 xavi.rmz 2011-03-09 05:05:42 -0800 I've also ran into this problem.

Indeed! finishJSTest() in js-test-pre.js checks that successfullyParsed is true. 405229 5 93764 kling 2011-05-17 12:26:20 -0700 Comment on attachment 93764 Proposed patch Clearing flags on attachment: 93764 Committed r86695: <http://trac.webkit.org/changeset/86695> 405230 6 kling 2011-05-17 12:26:29 -0700 All reviewed patches have been landed.
