From 49f088f2db21816f4b453ab4a22442ac031ab9bd Mon Sep 17 00:00:00 2001 From: Anton M Date: Wed, 10 Nov 2010 00:36:53 +0100 Subject: [PATCH] Partially revert commit a64dc0405064d68c7b7cd0f0fc8ea60086cbcd21. Removing the conditional was too liberal as now attr() would even work on plain javascript objects. Keeping a check to make sure it is at least a DOM Node is appropriate. Using nodeName as in the commit which introduced the nodeType === 1 check seems plausible. --- src/attributes.js | 138 +++++++++++++++++++++++----------------------- 1 file changed, 70 insertions(+), 68 deletions(-) diff --git a/src/attributes.js b/src/attributes.js index 4824c2902..c055fceb6 100644 --- a/src/attributes.js +++ b/src/attributes.js @@ -205,7 +205,6 @@ jQuery.fn.extend({ if ( rradiocheck.test( elem.type ) && !jQuery.support.checkOn ) { return elem.getAttribute("value") === null ?
