Bug 13719 – Setting an href or src DOM attribute to null does not give the same results as Firefox

• Component: DOM
• Status: RESOLVED CONFIGURATION CHANGED

[Sam Weinig]

When setting an href or src DOM attribute (eg. HTMLLinkElement.href or HTMLIFrameElement.src) we set the attribute to the null string while Firefox sets it to a URL to the page it self.  We should investigate what IE does and decide which behavior is most appropriate.

An html page to manually check the several browsers

This test case allows to set a full url or null to the href attribute. Then it displays the final value of the href.

When i click on "Set to null":
- with IE6 (XP, SP2) i get: "href is now:null"
- with FF 2.0.0.6 i get: "href is now:file:///C:/Documents%20and%20Settings/ricardvi/Desktop/13719.html" (which is the local url to the test case on my box)

Hope this test help to choice the behavior for webkit :)

I am unable to reproduce this bug in Safari 15.6 on macOS 12.5 using attached test case.

From test case, setting "null" leads to following URL - https://bug-13719-attachments.webkit.org/null and all browser (Chrome Canary 106 and Firefox Nightly 104) do the same. I think this might have been fixed along the way and can be considered as "RESOLVED CONFIGURATION CHANGED". Thanks!
