This article provides examples of key code for File Upload Based on jQuery Ajax for your reference. The specific content is as follows:

JS Code:

// SAVE function btnAdd () {var formData = new FormData ($ ("# frm") [0]); $. ajax ({url: "/Admin/ContentManage/SaveEdit", type: "POST", data: formData, contentType: false, // if it is set to false, the default processing of formdata by jQuery is avoided. XMLHttpRequest correctly processes formdata. processData: false. // The correct Content-Type success is automatically added only when it is set to false: function (data) {if (data = "OK") {alert ("saved successfully"); $. iDialog ("close"); // refresh the parent page} else {alert ("failed to save:" + data );}}});}
