jquery uses the dynamic rendering form feature to complete Ajax file downloads _jquery

Copy Code code as follows:

Ajax File Downloads
jquery.download = function (URL, data, method) {
Get URL and data
if (URL && data) {
Data is string or Array/object
data = typeof data = = ' String '? Data:jQuery.param (data);
Assemble the parameters into form input
var inputs = ';
Jquery.each (Data.split (' & '), function () {
var pair = this.split (' = ');
inputs+= ' <input type= "hidden" name= "' + pair[0] + '" value= "' + pair[1] + '"/> ";
});
Request Send requests
JQuery (' <form action= ' + URL + ' "method=" ' + (method| | ') Post ') + ' > ' +inputs+ ' </form> ')
. Appendto (' body '). Submit (). remove ();
};
