Processing of download files under Ajax Post submission method

Ajax is not able to download files directly, so it is generally done by a hyperlink to download a file

But when it comes to the need to send a lot of data to the server to download again, the form of hyperlinks is a bit bad to see,

/*=================== Download file * options:{* URL: ',  //* Data:{name:value},//data to be sent * method: ' Post ' *} */var Downloadfil E = function (options) {    var config = $.extend (True, {method: ' Post '}, options);    var $iframe = $ (' <iframe id= "down-file-iframe"/> ');    var $form = $ (' <form target= "down-file-iframe" method= "' + Config.method + '"/> ');    $form. attr (' action ', config.url);    for (var key in Config.data) {        $form. Append (' <input type= "hidden" name= "' + key + '" value= "' + Config.data[key] + '/> ');    }    $iframe. Append ($form);    $ (document.body). Append ($iframe);    $form [0].submit ();    $iframe. Remove ();

Leave it for backup.
