通过JQuery AJAX一起发送FormData和String数据吗？

var fd = new FormData();var file_data = $('input[type="file"]')[0].files; // for multiple filesfor(var i = 0;i<file_data.length;i++){    fd.append("file_"+i, file_data[i]);}var other_data = $('form').serializeArray();$.each(other_data,function(key,input){    fd.append(input.name,input.value);});$.ajax({    url: 'test.php',    data: fd,    contentType: false,    processdata: false,    type: 'POST',    success: function(data){        console.log(data);    }});

添加了一个

for

.serialize()

.serializeArray()

.each()

FormData
