These two days to make a judgment of the browser type and version number of the business, record the relevant JS code: Copy Code code as follows: function Allinfo () { var ua = navigator.useragent; UA = Ua.tolowercase (); var match =/(WebKit) [\/] ([\w.] +)/.exec (UA) | | /(opera) (?:. *version)?

Therefore, the final solution is obtained: in IE, bind the onpropertychange event to the checkbox, and in FF, bind the onchange event to it. The Code is as follows:Copy codeThe Code is as follows:Var ua = navigator. userAgent. toLowerCase ();Var s = null;Va

In general, we can direct the URL to a file under DocumentRoot to guide the user to download the file. However, in this way, there is no way to do some statistics, permission checks, and so on. therefore, we often use PHP for forwarding to provide users with file downloads. The code is as follows: $ File = "/tmp/dummy.tar.gz "; Header ("Content-type: application/octet-stream "); Header ('content-Disposition: attachment; filename = "'. basename ($ file ).'"'); Header ("Content-Length:". filesi

The getYear () function is not recommended long ago, because it is incorrectly displayed in Firefox, And the getFullYear () function is recommended.Firefox does not support the innerText attribute.
