[jira] [Commented] (HBASE-8532) [Webui] Bootstrap based webui
compatibility for IE.
[ https://issues.apache.org/jira/browse/HBASE-8532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13656065#comment-13656065 ]
Julian Zhou commented on HBASE-8532:
------------------------------------
IETester(http://www.my-debugbar.com/wiki/IETester/HomePage) is a tool for testing page in different IE versions.
Seems there still got css rendering issue in IE 9 in standard mode.
There is another issue for IE 8 and older versions. IE 8 and older versions could not recognize "'" as "'". So we should use entity code "'" instead for "'". This issue is introduced by "escapeXML()" function added in .jsp pages. excapeXML will convert the "'" to "'". But in some way, may need to convert to "'" for the case of IE 8 (IE 9 looks like already support to recognize "'").

> HBASE-7425 brings bootstrap based webui to hbase. While trying on trunk version, Firefox works well, but IE 8/9 layout and style look strange due to compatibility issue. Add "<!DOCTYPE html ...>" at the beginning of all jamon html/jsp templates to fix it.
> Seems HBase-2110 had a work to comment out the DOCTYPE for all .jsp to make the browser run the pages in Quirks mode (http://en.wikipedia.org/wiki/Quirks_mode) due to jetty issue at that time?
> To support the compatibility of webui across browsers (IE/Firefox/Chrome, etc.), there are some guidelines for choosing rendering the page under standard mode or quirk mode:
> http://en.wikipedia.org/wiki/Quirks_mode
> http://hsivonen.iki.fi/doctype/
> According to document, "<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">" has the most extensive compatibility even for HTML 5. According to my test, add this could make webui works in IE (standard mode), while Firefox could not work well with styles. Looks like if in Firefox, we still need the quirk mode (no DOCTYPE declaration).
> So just adding conditional DOCTYPE declaration for IE,
> <!--[if IE]>
> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
> <![endif]-->
> this could make webui works for both IE and Firefox, also for Chrome and other browsers.
