New jquery.placeholder.js is slow/placeholder text does not disappear in IE8
Closed, DeclinedPublic


When log in to wikipedia the new jquery.placeholder.js (gerrit 98137) is used on Special:UserLogin. When the cpu is high, and the username is typed and than with tab the password field is selected and the password is typed, sometimes the first letters of the password are missing.
Sometimes the whole placeholder text is select and will stay in the input box.

Please revert or fix the new jquery.placeholder.js. Thanks.

This was previously raised in the comments on that change by Umherirrender,
but I was unable to reproduce the issue quickly and did not have time to
poke at it more vigorously. :(

qunit tests under IE8 fails for jquery.placeholder

jquery.placeholder: emulates placeholder for <input type=text> (3,
19, 22)

  • $el.val("") should change the value attribute
  • $el.val("") should re-enable placeholder class
  • $el.placeholder(<string>) should update the displayed placeholder value

jquery.placeholder: emulates placeholder for <input type=email> (3,
19, 22)

  • the same as above

jquery.placeholder: emulates placeholder for <input type=tel> (3,
19, 22)

  • the same as above

Expected is a value, but result is a empty string. Please have a
look. Thanks.

All tests pass for me on IE8 :o

Looks like a race condition, when cpu is high. Because sometimes it
fails with all tests and pass when testing the module only, but it
also possible that the module test failed. Seen with monobook and

Microsoft will drop support for Windows XP and therefor the user with Internet Explorer will decrease. Nobody will care about that in 3 months, marking wontfix. Other bugs also open to track the placeholder problems on some browser versions, see bug 48918 or bug 47057

If Microsoft drops support does not matter if in reality enough people still use it. Plus we are not actively against fixing this and would accept patches, hence reverting WONTFIX and setting low priority.
