Bootstrap-fileinput component passes additional parameters on upload

Workaround

The key configuration parameter is Uploadextradata
The specific code is as follows:

 Method for obtaining additional parameters Foddertype = function () {return $ ("#fodderTypeSelect"). Val ();　　            }; Initialize the Fileinput control (first initialization) function Initfileinput (Ctrlname, fileextensions, fileSize) {var control = $ (' # ' +            Ctrlname);                Control.fileinput ({language: ' zh ',//Set Language Uploadurl: "/wxmedia/imageupload",//uploaded address Allowedfileextensions:fileextensions,//receive the file suffix showupload:true,//whether the upload button is displayed SHOWC Aption:true,//whether the title is displayed, Maxfilesize:filesize * 1000,//unit is KB, if 0 means no limit to file size Browseclass: "BT                N btn-primary ",//Button style Previewfileicon:" <i class= ' Glyphicon glyphicon-king ' ></i> ",                    Initialcaption: "Please select upload footage", uploadextradata:function (Previewid, index) {//Key points for extra parameters                    var obj = {};                    Obj.fodder = Foddertype ();                    Console.log (obj);    return obj;            }            }); }
