Detecting IE browser version using PHP

阅读更多关于 Detecting IE browser version using PHP

问题 I'm using $_SERVER['HTTP_USER_AGENT'] to detect user's browser. When I run the var_dump on my localhost on IE8 it returns: ...compatible; MSIE 8.0; ... But when I upload it to my host (godaddy), I get: ...compatible; MSIE 7.0; ... What's the problem? 回答1: Check for the word TRIDENT in the string. The compatibility-thing is ie in compatibility-mode. Google it if you want to know what it means. However, the term trident is only ie8+. Edit: Also, you can set a headder/meta-tag to force ie8-mode

问题 This question already has answers here : Detect IE version (prior to v9) in JavaScript (37 answers) Closed 5 years ago . I used to check it this way: $.browser.msie && $.browser.version == 8 But it seems that $.browser has been removed from the later versinos of jQuery, So, How can I check that with just pure javascript? I tried: isIE8: navigator.appVersion.indexOf("MSIE 8") > 0 Wich seems to Do it, but it doesn't look that good and actually looks like it have many flaws... Any better aproach

问题 One of my javascript sources had an extra comma that was throwing an error in IE8. So I opened up my editor, deleted the comma, and saved. I reloaded IE8, but it was still pulling the old js file. I deleted everything in "Delete Browsing History...", and restarted the browser. It is still pulling the old file. I even set up a log on my server to show whenever the js file was requested.
