Details
Found an instance in which the with statement fails to operate correctly. Given the following page: <html> <head> <title>JavaScript with text</title> <script type="text/javascript"> <!-- function with_test() { alert('image src is ' + document.images['wait'].src); alert('image src length is ' + document.images['wait'].src.length); with (document.images['wait']) { alert('image src is ' + src); alert('image src length is ' + src.length); } } // --> </script> </head> <body> <img src="mozilla.jpg" name=wait> <form action="#"> <input type=button onClick="with_test()" value="Test"> </form> </body> </html> When with_test is called the first two alert statements will work fine and the next two within the with { } statement will both fail with the message "src is not defined".

Sending to Brendan because this is so similar to bug 38215. Is it in fact a duplicate?

This is the same class of bugs as 38215, and could be combined. Apparently, the src property of image objects (and only that property) is handled only by the underlying C++ object's GetProperty routine, which uses an inefficient string compare to specialize its behavior for "src". This is the same raw deal as in bug 38215, just for image.src rather than for location.href. There are probably other specific bugs of this class. I would say let's combine bugs under the general class "DOM must use resolve, not getProperty, to be lazy" (or similar words). /be
