I am trying to send a file to the server to do some processing. This is working perfectly fine using the below code:
var formData = new FormData(); formData.append('file', $('#fileUpload')[0].files[0]); options = JSON.stringify(options); // {"key": "value"} $.ajax({ url: "url", type: "POST", data: formData, processData: false, contentType: false, success: function (data) { }, error: function (msg) { showMsg("error", msg.statusText + ". Press F12 for details"); console.log(msg); } }); However, what I am trying to do is not only send the FormData but a json object as well. I am trying to do something like below:
var formData = new FormData(); formData.append('file', $('#fileUpload')[0].files[0]); options = JSON.stringify(options); // {"key": "value"} $.ajax({ url: "url", type: "POST", data: { "formData": formData, "options": options }, //dataType: "json", //processData: false, //contentType: false, success: function (data) { }, error: function (msg) { showMsg("error", msg.statusText + ". Press F12 for details"); console.log(msg); } }); When I do this, I get the error message of Uncaught TypeError Illegal invocation From what i've researched, I cannot find any examples of sending form data like this. Does this need to be restructured of is there some other way to send a json object along with the form data?
