javascript - Is emulation mode in IE11 same as setting meta EmulateIE7 tag? -


for ie11 browser use see message on console :

“html1122: internet explorer running in enterprise mode emulating ie8.”

searching error code on https://msdn.microsoft.com/query/dev12.query?appid=dev12idef1&l=en-ie&k=k(vs.webclient.help.html1122) displays : “this mode configured management specific sites. if individual user needs turn off on webpage, uncheck enterprise mode option in tools menu. more management of enterprise mode, see documentation.”

this fine want control setting meta tag.

will adding <meta http-equiv="x-ua-compatible" content="ie=emulateie7"> head have same affect "running in enterprise mode emulating ie8" ?

no. using content="ie=8" similar results not same.

enterprise mode ie (emie) special mode designed provide greater compatibility ie8 possible using x-ua-compatible. ie8 standards mode introduced ie9 , organizations able use migrate legacy apps. other organizations struggled, however. because there reliance on then-current behavior of ie8 standards mode, ie11 introduced emie still struggled.

some of complexity led clean break being introduced ms edge.

to best of knowledge, cannot enable or disable emie through markup. (you can through group policy, however, , may if concern related rolling out number of machines.)

hope helps...
