Description: see steps to reproduce 1. First of all, help/help2.js installed in LibreOffice 6.2.1.2 release did not work with IE11 due to unsupported arrow function https://gerrit.libreoffice.org/#/c/69005/ the part should be cherry-picked to 6.2 branch if it's not yet. 2. When I displayed the source in IE11, there was another error reported in the debugger. help/index.html complained that there is no definition for getParameterByName as defined in help/help.html https://opengrok.libreoffice.org/xref/help/help3xsl/help.html?r=5ccfc30b#16 I copied all the code to index.html, without understanding well. 3. I did several tries for the same steps to reproduce after each fix for the following problems. 3-1. IE11 complained that there is no startsWith. https://opengrok.libreoffice.org/search?full=startsWith&project=help https://stackoverflow.com/questions/36213455/add-startswith-in-ie-11/36213464 3-2. IE11 does not support Element.matches https://stackoverflow.com/questions/37304037/why-my-code-dont-working-in-ie11 https://opengrok.libreoffice.org/xref/help/help3xsl/help.js?r=a678c053#125 https://opengrok.libreoffice.org/xref/help/help3xsl/help.js?r=a678c053#129 3-3. :scope in querySelectorAll is not supported https://github.com/ademilter/bricklayer/issues/13#issuecomment-219662153 4. Even when I resolved all these above with tentative fix on my own machine, I tried the Step To Reproduce to see if it works,and it didn't. because LibreOffice tried to search for the "en-US" help that I did not install. C:\Program Files\LibreOffice\help\en-US\text\shared\guide\startcenter.html the cause was that IE11 did not return correct value for has() method in Set Object https://opengrok.libreoffice.org/xref/help/help3xsl/help2.js?r=3d0fcf7a#143 and the existingLang function returned en-US. 5. Still rendering/layout issue seems remaining, but I'm not an expert in that area. at least no complaints are given by the debugger now. Steps to Reproduce: 1. Install LibreOffice 6.2.1.2( Other than en-US is preferable, I used ja) 2. Install Offline Help pack( Don't install the help pack for en-US) 3. Set your default web browser to IE11 4. Run LibreOffice 5. Press F1 Actual Results: Help is not shown even after accepting scripts. Expected Results: Help is shown in UI locale Language Reproducible: Always User Profile Reset: No Additional Info: バージョン: 6.2.1.2 (x64) Build ID: 7bcb35dc3024a62dea0caee87020152d1ee96e71 CPU threads: 4; OS:Windows 10.0; UI render: GL; VCL: win; ロケール: ja-JP (ja_JP); UIの言語: ja-JP Calc: CL
forgot to add the source code pointer for :scope https://opengrok.libreoffice.org/xref/help/help3xsl/help.js?r=a678c053#132
Thanks a lot for testing and the research. I will look into these tomorrow. Going to use a bunch of polyfills for most of them. Regarding the CSS layout, IE11 will see the mobile layout. I don't think it makes sense to invest in replicating the CSS grid setup with IE (even though it is possible with https://github.com/postcss/autoprefixer ). I think starting from next year we should think of dropping support for IE11. Maybe not for the crucial JavaScript bits that do the redirection, but mostly anyway.
A more fundamental problem is that IE11 users have to enable this setting to even use local JS: https://stackoverflow.com/a/40675005/3057764 Something we cannot do anything about.
