話不多說，直接上代碼

1,htm代碼

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title>Title</title>    <script type="text/javascript" src="__PUBLIC__/home/js/jquery-1.11.0.js"></script></head><body><form class="form-horizontal" role="form" id="myForm"      action="/index/fileupsend" method="post"      enctype="multipart/form-data">    選擇文件:<input type="file" id="file1" /><br />    <input type="button" id="upload" value="上傳" />    <span id="imgWait"></span></form><script>    $(function () {        $("#upload").click(function () {            $("#imgWait").html("上傳中");            var formData = new FormData();            formData.append("myfile", document.getElementById("file1").files[0]);            $.Ajax({                url: "/Home/index/fileupsend",                type: "POST",                data: formData,                /**                 *必須false才會自動加上正確的Content-Type                 */                contentType: false,                /**                 * 必須false才會避開jQuery對 formdata 的默認處理                 * xmlHttPRequest會對 formdata 進行正確的處理                 */                processData: false,                success: function (data) {                   if(data){                        alert("上傳成功！");                   }                    $("#imgWait").html("上傳成功");                },                error: function () {                    alert("上傳失敗！");                    $("#imgWait").hide();                }            });        });    });</script></body></html>2，php代碼
public function fileupsend(){    $type_pic = $this->file_upload('1',array('jpg', 'gif', 'png', 'jpeg'),'filetest','myfile');    echo $type_pic['img_path'];}就這樣實現(xiàn)了ajax異步提交圖片
